Atlantic History and the Slave Trade to Spanish
America

1 The first African slaves probably arrived in 1501 from Seville, Spain, but not on a slave voyage in
the usual sense. António de Almeida Mendes, “The Foundations of the System: A Reassessment of the
Slave Trade to the Spanish Americas in the Sixteenth and Seventeenth Centuries,” in David Eltis and

2 Spain’s American possessions, the size and complexity of which should not be underestimated,
were the linchpin of an empire that was genuinely global in scope during the eras of Hapsburg and
Bourbon rule. In Europe, it stretched from the Spanish Netherlands to Sicily, and from Oran in North
Africa to the Canary Islands. It included the Philippines in Asia, and the Mariana Islands and Guam
in Oceania. During the Iberian Union, which lasted from 1580 to 1640, the Spanish crown also ruled
over Portugal and the entire Portuguese empire, including Brazil and Angola, and territories in North
Africa, India, and the Moluccas, among many other sites. Until the Constitution of 1812, Spanish territories in the Americas were considered kingdoms or provinces under the rule of the Spanish crown
(much like the kingdoms of Aragon and Naples), and were typically grouped into larger administrative
units known as audiencias. The audiencias, in turn, nominally fell under the jurisdiction of viceroyalties,
though some retained a considerable degree of autonomy. The main center of Spanish power in North
America was the Viceroyalty of New Spain, which encompassed all of modern Mexico plus the provinces
of Upper California, New Mexico, and Texas. Stretching across the circum-Caribbean, the Audiencia
of Santo Domingo included the islands of Hispaniola, Puerto Rico, Jamaica, and Cuba, as well as Florida.
During the sixteenth and seventeenth centuries, it also included most of present-day Venezuela and its
neighboring islands, and it would add the Floridas (again) and Louisiana during the eighteenth century.
The neighboring Audiencia of Guatemala encompassed most of Central America, including territories
that correspond to the modern nations of Guatemala, Nicaragua, El Salvador, Honduras, and Costa
Rica. Immediately to the south, the Audiencias of Panamá, Santa Fe, and Quito—more or less corresponding to the modern nations of Panamá, Colombia, and Ecuador—fell within the jurisdiction of
the expansive Viceroyalty of Peru, as did the audiencias of Charcas, Chile, and Lima (where the viceroyalty was headquartered), including territories in what are today Peru, Bolivia, Chile, Argentina, Uruguay, and Paraguay. In short, Spain laid claim to all of South America, with the exceptions of Brazil and
the “Wild Coast” of Suriname and the Guyanas; the Viceroyalty of Lima ostensibly held sway over this
vast region until the establishment of additional viceroyalties and audiencias as in Buenos Aires during
the eighteenth century.

WITHIN HALF A CENTURY OF COLUMBIAN CONTACT, the most powerful state in Europe
had taken over the two most powerful polities in the Americas: the Aztec and Inca
empires. From that point until at least 1810, Spanish America was the largest and
most populated European imperial domain in the New World, stretching eventually
from California to Buenos Aires. Both the first and the last slave voyages to cross
the Atlantic disembarked not very far from each other, in the Spanish colonies of
Hispaniola (1505) and Cuba (1867).1 This continent-sized group of colonies developed the first and, until the late eighteenth century, the largest free black population
in the Americas.2 Spanish America was therefore the part of the Americas with the
most enduring links to Africa. Yet while the French, the British, and even the Portuguese empires have reasonably precise data on the origins, composition, and de-

mographic evolution of their black populations, most of the information we have for
the Spanish colonies is on nineteenth-century Cuba. How puzzling that we know less
about the size, nature, and significance of the African connection with Spanish
America, especially the Spanish role in the slave trade, than we do about any other
branch of the transatlantic traffic.3 While there is an ancient and well-developed
historiography on Latin America, Africans in the Spanish-speaking Americas, and
indeed the Spanish themselves, have yet to receive their due in Atlantic history—at
least for the years after 1640.
Using the Trans-Atlantic Slave Trade Database at www.slavevoyages.org, as well
as new archival sources, we have conducted a new evaluation of the slave trade to
the Spanish colonies. Our reassessment has given us a new appreciation of not only
the African presence in the Spanish Americas, but also—given the links between
slavery and economic power before abolition—the status of the whole Spanish imperial project. Overall, more enslaved Africans permanently entered the Spanish
Americas than the whole British Caribbean, making Spanish America the most important political entity in the Americas after Brazil to receive slaves. We now believe
that as many as 1,506,000 enslaved Africans arrived in the Spanish Americas directly
from Africa between 1520 and 1867. We further estimate that an additional 566,000
enslaved Africans were disembarked in Spanish America from other European colonies in the New World, such as Jamaica and Brazil. Our new, upwardly revised
figures will appear on the updated estimates page of the Voyages section of the
Trans-Atlantic Slave Trade Database (hereafter Voyages); however, it is important
to note that the database does not address the trans-imperial intra-American slave
trade, a lacuna that obscures the picture of how the slave traffic functioned in Spanish
America.
Two-thirds of the more than two million enslaved Africans arriving in the Spanish
Americas disembarked before 1810—prior to the era of large-scale sugar cultivation
in Cuba and Puerto Rico—which necessitates a reconsideration of the real significance of slavery in Spain’s American colonies. This large inflow is indeed remarkable when we remember that the labor force sustaining the most valuable export of
these colonies—silver—was largely Amerindian. In every other European empire in
the Americas, by contrast, it was slaves of African descent who produced all significant exports until well into the nineteenth century. British military and industrial
ascendancy in the eighteenth century and the meteoric rise and fall of St. Domingue
have blinded scholars to the continued expansion of the Spanish colonies and their
populations of African descent through to their independence. Nevertheless, black
populations had a key role in the growth of the Spanish Americas before 1800.
In addition to the importance of the slave trade for the colonization and development of the Spanish Americas, the Spanish colonies have significance for the
broader history of the transatlantic slave trade, and consequently for Atlantic history.
The history of the slave trade to Spanish America had implications for the whole

Atlantic in the sense that it drew on all European branches of this traffic, and captives
from all African regions engaged in this traffic landed in at least one of the many
Spanish colonies. It was not only the metropolitan authorities of the different European powers who fought over and negotiated slave-trade contracts, but also, at the
local level, officials, merchants, and Africans—often the very subjects being trafficked—who shaped the trans-imperial trade flows of the New World.
For the first decades of the slave traffic, as for the last, the slave trade provides
a previously overlooked means of gauging the economic strength of the Spanish
Americas relative to other European empires. Riverine gold and copper mined by
slaves guaranteed the preeminence of Hispaniola prior to the invasion of the mainland, and Cuba’s sugar sector ensured that this island probably had a higher per
capita output than the United States in the mid-nineteenth century, as well as the
first railroad network in Latin America.4 But even in the eighteenth century, exports
to Europe from the Spanish Americas had a far greater value than those from their
British, French, Dutch, and Portuguese counterparts. In 1700, the total output of the
non-Hispanic Caribbean, more than 90 percent of which consisted of sugar and sugar
by-products, amounted to 1.7 million pounds sterling or 7.6 million pesos.5 In the
Spanish possessions, by contrast, bullion production alone averaged 8 million pesos
annually from 1696 to 1700, an amount that made them also more valuable to Spain
than Brazil was to Portugal, and than both mainland and Caribbean colonies were
to the British. Seventy years later, the supremacy of the Spanish was only slightly
eroded. The total annual value in pesos of French Caribbean output was 23.1 million,
and of British, 16.2 million, whereas the Spanish Empire generated exports worth
close to 31 million pesos—29.2 of which was bullion. Even if we include the thirteen
mainland colonies in the British total, the Spanish Americas still come out well
ahead—it is just that they no longer out-produced all their competitors combined.6
The cession of Jamaica to Britain and St. Domingue to France apparently did not
enable the British and French to catch up prior to the era of independence; Spanish
America grew vigorously until at least 1800.7 Alongside specie exports and population estimates, the slave trade can be used as an indicator of the continued dynamism of Spanish America in the Atlantic prior to 1800, and in Cuba specifically

agro-pastoralists of the temperate highlands and latitudes; they avoided the humid tropical lowlands
where possible,” unlike the Portuguese in Brazil. Melville, “Land Use and the Transformation of the

colonies with that of the Spanish, where the creole elite outside the plantation sectors were “sunk in
provincial torpor.” For a more realistic view of how the Spanish Empire shaped the Atlantic world, see

to 1867. Economic divergence between the Spanish Americas, on the one hand, and
the United States, on the other, began only in the nineteenth century.8
Indigenous peoples mined most of the silver that underpinned colonial exports,
but the role of Africans has been poorly understood in an Atlantic world historiography that has emphasized export-oriented plantations. With the possible exception of nineteenth-century Cuba, the Black Atlantic is still defined in terms of links
between Africa, on the one hand, and the English, French, and Lusophone worlds,
on the other. From 1640 to the end of the eighteenth century, the Spanish Empire’s
links with Africa are seen as moribund, compared to the millions of Africans pouring
into the non-Spanish Americas.9 References to a “second Atlantic” have recently
appeared, denoting the period dominated by Northwestern Europe (England,
France, and to a lesser extent the Netherlands), in contrast to the Iberian-led “first
Atlantic.”10 Our calculations counter this view. The slave trade remained of central
importance during all four centuries of Spanish colonialism in the New World. The
slave trade was pivotal not just for the early colonization of the Spanish Americas,
when varied regional economies emerged in both highlands and lowlands. It was also
of key importance throughout the eighteenth century, when the Spanish transformed
their empire.11 Thereafter it sustained the rise of export-oriented sugar and coffee
plantations in Cuba and Puerto Rico.
Figure 1 provides an overview of our new assessment. While the major British
(and indeed Portuguese) transatlantic slave trade rose and fell in a regular parabola
from the seventeenth to the nineteenth centuries, Figure 1 shows the bi-modal pattern of the traffic to Spanish America, with a first peak around 1620 and a second,
higher peak in the nineteenth century. The U shape in between was emphatic. But
the figure also adds information on intra-American voyages, that is, slave expeditions
departing from the non-Hispanic Caribbean and Brazil for the Spanish colonies.
Atlantic History and the Slave Trade to Spanish America
437
More than a quarter of the slaves arriving in Spanish America had departed from
colonies of other European powers in the New World rather than directly from Africa. Figure 1 shows that the lowest point of the transatlantic Spanish trade’s U trend
was offset to some extent by the trans-imperial intra-American traffic from 1640 until
its ending by 1820, during the era of independence for the Spanish American mainland, but not completely so.
Cartagena, Veracruz, Buenos Aires, and Hispaniola received the majority of
slave arrivals shown by the first peak in Figure 1, with many captives then re-exported
to additional destinations, including Lima and Mexico City. By contrast, Cuba and
Puerto Rico account for almost all of the second peak. Nevertheless, some regions,
such as the Rı́o de la Plata—today’s Argentina and Uruguay—and to a lesser extent
Venezuela, did experience this U-shaped trend. The Rı́o de la Plata both absorbed
slaves and was a major entrepôt, supplying Chile and Peru, whereas slaves arriving
in Venezuela tended to remain there. In Mexico the slave trade declined from the
1650s to the last recorded transatlantic slave arrival in 1735. There was nevertheless
a vibrant and naturally growing population of African ancestry, probably made possible by the less brutal working conditions (notably the absence of a dominant sugar
sector) and Spain’s reliance on a large Amerindian labor force, both coerced and
free, for the harsh work in the mines.
The dual-peak structure of the slave trade to Spanish America also points to two
major cycles of demographic change related to African arrivals (Africanization) and
the intermixing of indigenous peoples, Africans, and Europeans in the Americas
(mestizaje). These cycles provide a chronological framework that helps to explain
why identities evolved differently in the Spanish colonies than they did in what beAMERICAN HISTORICAL REVIEW

HOW CAN WE BE SURE THAT the broad trends shown in Figure 1 are correct? To explain
the Spanish slave trade, we first have to define it. Two rather different concepts are
possible—on the one hand, the traffic into the Spanish colonies; and on the other,
the smaller and less significant slave trade carried out on Spanish vessels. For anyone
working with official documents of the early modern era, it must often appear that
incompetence, smuggling, venal officials, and the hazards of everyday life undermine
the reliability of any state-generated data. For the slave trade, skepticism takes the
form of doubt regarding whether every actual voyage could have left behind evidence, and whether the numbers of people on board such vessels are likely underreported. These problems loom large for the Spanish Atlantic, notwithstanding the
fact that the Spanish bureaucracy probably generated more documentation per imperial subject than any other empire before the nineteenth century. Thus, for Colin
Palmer, tracking the British asiento in the first half of the eighteenth century, “Contraband traders . . . may have sold the Spaniards as many or even more slaves than
their legal counterparts but this dimension of the trade . . . will forever be confined
to the realm of scholarly speculation.” Juan Amores’s study of the traffic into Cuba
(1760–1790) describes an uncontrollable slave trade and a huge contraband, with
officials pointing to a coastline, “almost all of it open and unguarded.” For Leslie
Rout, “all efforts aimed at making an acceptable estimate of the Spanish American
slave traffic [are] innately flawed.”12 Contraband, slaves landed in Spanish colonies
outside the official record, seemed impossible to stop.13
12 In the context of the transatlantic slave trade, asientos were monopoly contracts in which the
Spanish crown granted permission to individual merchants or merchant houses to orchestrate the transportation of a fixed number of enslaved Africans to specific Spanish American ports over a set period
of time. On contraband, see Colin A. Palmer, “The Company Trade and the Numerical Distribution of
Slaves to Spanish America, 1703–1739,” in Paul E. Lovejoy, ed., Africans in Bondage: Studies in Slavery
and the Slave Trade (Madison, Wis., 1986), 27– 42, here 40; Juan B. Amores, Cuba en la época de Ezpeleta,
1785–1790 (Pamplona, 2000), 133; Rout, The African Experience in Spanish America, 66. We thank Henry
Lovejoy for drawing our attention to Amores’s book.
13 Due to limitations of space here, we cannot adequately address the extensive body of scholarship
devoted to examining the nature and significance of contraband in colonial Spanish America. Suffice
it to say that Spanish sources prior to 1800 rarely used the word contrabando to describe contraband
trade, which is illustrative of the very thin line (if such a line even existed) between legal trade and

came the United States. While some Spanish American colonies experienced a cycle
of Africanization followed by mestizaje during the first slave-trade peak, and others
experienced the same during the second peak, some regions can be said to have
experienced both. The relative weight of these two processes varied across the Spanish colonies. With the possible exception of New Orleans (itself a Spanish colony
from 1769 until 1803), it is difficult to imagine any city in the early-nineteenth-century United States in which people of mixed origins outnumbered those of either full
European or African ancestry, as was the case in Venezuela in 1810. For the antebellum U.S., it is equally difficult to visualize the almost complete disappearance
of “black” as a category of identity in official records, subsumed by multiple mestizo
labels, as in early independent Mexico. Further, there was no equivalent in the
United States of the diversity of African-based associations and religions that existed
in Cuba and the Rı́o de la Plata as late as the 1830s.

contraband. Seemingly an oxymoron, the category of “legalized contraband” best describes the interplay
of strategies between metropolitan and colonial authorities on this issue.

But is the situation quite so hopeless? For the British, French, Dutch, and LusoBrazilian slave trades, internal and external (to the state, that is) checks are possible
for some periods, so that one might be able to assess the probability that ships were
omitted from the Voyages database.14 Such checks are not yet possible for most of
the Spanish transatlantic slave trade, but readers should keep in mind a broader
perspective on the size and direction of the traffic into Spanish colonies. During the
second half of the seventeenth century, the era in which Britain entered the transatlantic slave trade and solidified its presence in the Americas, observers in Jamaica
indicated that slave prices were higher in the Spanish markets than in the British
Caribbean.15 And Joseph Massie, an acute observer of the English sugar business,
pointed out in a book published in 1759 that in the previous thirty years, low slave
prices had underpinned the success of the English plantations.16 Contraband was
significant, but it was not large enough to integrate the Spanish and British markets
in the Caribbean to the extent that price differences reflected no more than the cost
of sailing from one market to another. After 1790, by contrast, captains typically
checked out slave prices in at least two of the major markets of Kingston, Havana,
and Charleston (where prices by then were similar) before deciding where to sell.
The same voyage from Africa frequently shows up in more than one of these ports
within the space of a month.
New archival data have enabled us to reassess the key routes by which Africans
entered the Spanish Americas, as well as to carry out a more refined inquiry into
contraband. As a result, we are able to shed new light on two large branches of the
slave trade to Spanish America: the transatlantic traffic for the period before the
breakup of the Iberian Union (when Portugal and its colonies were under the Spanish crown) in 1641, and the intra-American traffic that from 1661 to about 1800
became the Spanish Americas’ major source of African slaves. We offer little new
information on nineteenth-century Cuba and Puerto Rico, a branch of the trade that
has been subject to greater scholarly scrutiny than inflows into other Spanish American colonies.

Note: The Spanish and British totals have been adjusted to reflect the changing status of Trinidad.
On the 2010 estimates page of the Voyages database, Trinidad is classed as part of the British Americas
even though British occupation began only in 1797. Here, the 16,500 captives taken there before 1797
are reassigned to the Spanish Americas.
captives carried on Spanish vessels alone. The non-Spanish data in columns 1
through 5 and column 7 are all from the 2010 version of the Voyages database, but
the two Spanish columns—one for the Spanish Americas (column 6) and one for the
slaves transported under the Spanish flag (column 9)—are new. The Spanish figures
previous to 1641 draw on new archival data and in addition incorporate a fresh approach to estimating the large illegal influx of slaves into Spain’s colonies that occurred throughout the slave-trade era. Table 1 shows that in the pre-1641 period,
529,800 captives arrived in the Spanish Americas from Africa. Thus, according to our
calculations, almost 60 percent more Africans arrived in the New World than the
2010 Voyages estimate page displays. For the later period, too, new transatlantic
voyages to Venezuela and the Rı́o de la Plata have come to light.17 For the whole
period, we found that 14 percent more slaves entered the Spanish Americas directly

legajos in AGI-Contadurı́a, providing additional data for twenty-one voyages arriving in Nombre de Dios
(Panama), and one voyage arriving in Veracruz in the years 1549–1569.

parture records constitute our only source of information for many slaving voyages
up to 1580. Thus most volume estimates for the years prior to 1581—including Antonio Mendes’s estimates for those years, and the estimates page of Voyages based
on his work—are heavily influenced by research on slave-trade licencias, permits that
were awarded by the Spanish crown but did not necessarily result in slaving voyages.18
Our data for this period, by contrast, consist primarily of intended slaving voyages
and vessels that actually arrived in Spanish American ports. Despite the different
methodologies, the two approaches generate similar outcomes: 84,900 vs. 82,000
slaves for 1526–1580. For the period 1581–1640, we now have 583 more voyages than
are shown in the 2010 Voyages database. While the work of Enriqueta Vila Vilar
previously grounded our knowledge of the traffic during the Iberian Union, it now
appears that her data account for less than half of all known arrivals for the years
1595–1640 alone.19 More important than the additional voyages is the much clearer
idea of how many captives slave vessels carried when they arrived in the Americas.20
The improved data indicate that the slave trade to the early Spanish Americas has
been greatly underestimated.
The additional archival data permit us to take a new approach to the question
of contraband, slaves landed in Spanish colonies outside the official record. Of the
1,843 voyages recorded in our dataset, 748, or about 40 percent, have no information
on the number of slaves carried, leaving 1,095 for which we know at least one of three
indicators of how many were on board. The first is the number that captains declared
they had on board at the port of entry (800), the second is the number that the vessel
was licensed to carry before the voyage began (721), and the third is the number that
were actually carried (65). Voyages fell into this last group because they had become
the subject of intense investigation by colonial authorities. Such inquiries generated
sufficient data that we feel reasonably certain of knowing the actual number of slaves

Slave Trading in Santo Domingo at the End of the Portuguese Asiento Period,” Slavery & Abolition 35,
no. 1 (2014): 99–120.
22 Inspection of the resulting estimated values indicated some forty-seven anomalies for which further adjustment was required. For forty-eight cases, declared slaves in the historical record were equal
to or less than forty. Almost all of these were identified as non-specialist slave ships. For these we set
actual numbers equal to declared numbers. A further four cases turned out to have predicted values
(calculated from the regression equations) lower than declared slaves. For these, too, we substituted
declared values. The breakdown of the estimated 1,843 cases in the slave arrival column is as follows—65
with actual slaves reported, 52 with declared values, 979 with values predicted from registered slaves
(via a simple regression), and 747 assigned a simple average of 287.

24 Rescate (in this context meaning ransom or barter) referred to Spanish American colonists’ acquisition of untaxed merchandise and slaves from merchants who were not authorized by the House of
Trade in Seville. Merchants who eschewed Spain’s mercantilist Atlantic fleet system by engaging in this
type of direct commerce were often French, English, or Dutch traders arriving from non-Iberian colonies, or indeed from Western Europe. In many cases, these non-Iberian interlopers captured Spanish
or Portuguese vessels at sea, then sailed to Spanish American ports, where they would attempt to sell
any confiscated goods or captives. I. A. Wright, “Rescates: With Special Reference to Cuba, 1599–1610,”

on board. For some cases, we know two or all three of the indicators. On average,
we found that vessels were licensed to carry 156 slaves, and that, unsurprisingly,
captains declared they had 153 on board when they arrived in the Americas. By
contrast, the mean of the 64 Iberian slave ships (the 65th was a Dutch intruder) for
which we have data on actual slaves disembarked was 287, suggesting that vessels
delivered 80 percent more slaves than their captains were permitted to or admitted
to.21
A subset of these 64 voyages comprising 61 cases also contained information on
either licensed or declared numbers of captives, and thus we were able to estimate
a simple regression equation that allowed us to predict actual numbers on board for
the 1,030 individual voyages (1,095 less 65) for which the documents yield only licensed or declared numbers.22 For the 748 voyages that lacked information of any
kind on slaves, we simply assigned that same derived mean of 287. For the pre-1581
period, these procedures point to 84,900 captives disembarking (from 299 voyages)
in the Spanish Americas, with 444,900 (on 1,544 voyages) estimated to have arrived
between 1581 and 1640. This total is only for slaves coming directly from Africa, but
even so, it does not include several thousand Africans carried across the Atlantic
from Spain in small groups on the Indies fleets before 1641. Neither does it include
any of the 666 vessels that Huguette and Pierre Chaunu identified as registered to
depart from the Canary Islands for Spanish America before 1580, some of which
likely carried slaves off from Africa on the way.23 Finally, it includes only a few
documented incursions of French, English, Dutch, and Portuguese slave ships during
an era in which Spanish American colonists regularly engaged in rescate with such
intruders despite the risk of penalties.24 Thus, while our total for pre-1641 is substantially greater than previous estimates, it is readily apparent why we describe it
as “lower-bound.”
After 1640, slave arrivals to the Spanish Americas declined precipitously. Be-

26 A key resource for both approaches is a database of 7,000 intra-American slave-trade voyages first
assembled by Greg O’Malley and subsequently augmented. Although incomplete, the database allows
us to understand the broad direction and fluctuations of the flows into the Spanish Caribbean from

tween 1641 and 1789, Spanish vessels brought in only 23,500 captives directly from
Africa, compared to a non-Spanish transatlantic component accounting for 128,100
people, with the British alone carrying more than half.25 But in this same period, over
four times more captives entered the Spanish Americas from other parts of the
Americas, an activity summarized in row 8 of Table 1. Thus, soon after the collapse
of the Iberian Union, Spanish merchants began to purchase captives from ports
under the control of all European powers with a presence in the Americas, but especially the Dutch, Portuguese, and British. Sometimes this was under an asiento or
contract, and sometimes not. The surviving record means that estimating these various streams of coerced migrants requires us to focus either on departures from
major entrepôts such as Curaçao and Jamaica, or on arrivals at major Spanish American ports such as Cartagena. For the Rı́o de la Plata during the whole period, the
documentation is such that we can reconstruct an annual series of slave arrivals. For
all other regions under Spanish control, however, we use both approaches. Before
1789, we focus on what the foreign entrepôts sent to the Spanish colonies; after 1789,
data on inflows of captives into Spanish ports form the basis of our estimates.26
For the Spanish Americas, the intra-American slave trade had three major
branches. The best-known of these centered on Curaçao, the Caribbean island close
to Venezuela that, from 1662 to 1728 and intermittently thereafter, functioned as
an entrepôt through which captives on Dutch transatlantic ships reached Spanish
colonies. A second branch of the intra-American slave traffic originated in Barbados
and Jamaica, while a third, based in Brazil, delivered slaves to the Rı́o de la Plata
for more than two centuries until the 1830s alongside its better-known transatlantic
counterpart. In addition to these three distinct streams of traffic, there was a fourth,
multi-branched inflow of shorter duration that drew from a wide range of Caribbean
islands, intensifying between 1790 and 1808, and focused mostly on Cuba, as the
sugar boom got underway, and to a much lesser extent on Venezuela.
The outlines of the Dutch entrepôt trade in Curaçao have become much clearer
recently.27 Between 1658 and 1777 (but mostly between 1662 and 1728), Curaçao was
a major source for slaves entering the Spanish Caribbean islands and mainland, including the Gulf of Mexico. This internal traffic was almost identical to that part of
the Dutch transatlantic slave trade that disembarked slaves in the Dutch Caribbean,
given that most asentistas (holders of an asiento) in this period, whatever their nationality, resorted to Curaçao as they tried to meet their commitments to the Span-

Curacao departures taken to the Spanish Caribbean mainland. St. Eustatius supplied mainly the French
and British possessions, but the O’Malley database suggest that 10 percent went to Spanish colonies in
the seventeenth century, rising to 40 percent in the late eighteenth century. Of the 148,700 captives
disembarked in the Dutch Caribbean before 1790 (see http://slavevoyages.org/tast/assessment/estimates

30 The Spanish bought one-third of the captives brought to Jamaica and 15 percent of those going into
Barbados between 1661 and 1667; calculated from BNA, T70/869. For 1668 to 1700, we estimate an annual
average of 1,000 based on departures from Jamaica and Barbados in the first eleven years of the eighteenth
century—prior to the British asiento. The years 1668–1700 thus are not based on hard data but are broadly
consistent with comments on the Spanish traffic made by RAC agents in Jamaica and Barbados referenced
in Borucki, Eltis, and Wheat, “Notes on the Estimates of the Intra-American Slave Trade to the Spanish
Americas.” For annual re-exports of slaves from Jamaica, 1701–1789, see Richard B. Sheridan, “Slave Demography in the British West Indies and the Abolition of the Slave Trade,” in David Eltis and James Walvin,
eds., The Abolition of the Atlantic Slave Trade: Origins and Effects in Europe, Africa, and the Americas (Madison, Wis., 1981), 259–285, here 274. We use Sheridan’s preferred series, augmented with a series from Sheila
Lambert, ed., House of Commons Sessional Papers of the Eighteenth Century, 147 vols. (Wilmington, Del.,
1975), 67: 239, for two quinquennia. We add 10 percent to these figures to accommodate undocumented
transactions. We do not know where all these captives were taken, but O’Malley’s database shows destinations for a large sample of 722 voyages leaving Jamaica before 1790 that allows us to distribute the Jamaican
outbound series across the slave markets of the Caribbean. For the much smaller flows from other British
islands—which together supplied less than 10 percent of the Jamaican total—we draw directly on O’Malley’s
database. See IntraAmertoSpanAmer.xlsx at www.slavevoyages.org/tast/database/download.faces.

ish.28 Between 1658 and 1714, 63 percent of the Dutch slave traffic was directed to
the Dutch Caribbean (largely to disembark slaves destined for Spanish colonies) or
to Spanish America directly. Close to 116,000 slaves passed into Spanish America
through Dutch hands.29 If the Dutch were the first major suppliers of captives, the
British were not far behind. Spanish merchants began buying slaves from the Company of Royal Adventurers to Africa (the precursor of the Royal African Company)
in Jamaica and Barbados in the early 1660s and continued until at least 1801. As late
as the 1820s, several thousand English-speaking slaves are reported to have been
moved from British islands to Cuba, in this case by their owners. Overall we estimate
a total flow of 247,500 from British to Spanish jurisdictions.30 The third major intraAmerican source for slaves, Brazil, focused almost entirely on the Rı́o de la Plata
and was anchored mainly in Rio de Janeiro. A handful of pre-1641 transatlantic slave
voyages stopped first in Brazil (usually Pernambuco or Maranhão) before disembarking captives in Venezuela, Jamaica, Honduras, and Veracruz. New data suggest
that Hispaniola was a significant locus for unauthorized Brazilian-Caribbean shipping in the sixteenth century. After the mid-1600s, however, slave ships from Brazil
would not reach the Caribbean again until 1811. Slave traffic from Brazil to mainly
the Rı́o de la Plata (but including minor shipments to the Spanish Caribbean)
brought 136,100 captives, as Table 1 shows, which makes it larger than the Curaçao
traffic.31 In the pre-1790 era, slaves also arrived in Spanish colonies via the French
Atlantic History and the Slave Trade to Spanish America
445
and Danish islands.32 After 1789, captives could be entered at most Spanish American ports without restriction, with the result that records of arrivals from both foreign New World colonies and Africa become more abundant and more reliable.33
The transatlantic slave trade introduced 1.51 million slaves into the Spanish
Americas, and the intra-American traffic a further 0.57 million, for a total of 2.07
million Africans (after rounding). If the intra-American traffic is taken into account,
the Spanish areas received 80 percent more slaves than did the French Americas,

Moutoukias and Molina did not consult these two AGI sources. These sources list slaves arriving from
both Africa and Brazil; by attempting to isolate the latter and by applying the ratio of estimated to
declared slaves from the transatlantic traffic, we can obtain an estimate series. Between 1683 and 1777,
the Portuguese ferried thousands of slaves from Brazil to their outpost of Colônia do Sacramento—
across the Rı́o de la Plata from Buenos Aires—whence they were smuggled into Spanish territory. See
Enrique M. Barba, “Sobre el contrabando de la Colonia del Sacramento, siglo XVIII,” Academia Nacional de la Historia, Separata Investigaciones y ensayos 28 (1980): 57–76. For a transcribed copy of one
of Barba’s sources, see Anónimo, “Discursos sobre el comercio legitimo de Buenos Aires con la España
y el clandestino de la Colonia del Sacramento: Medios de embarazarle en la mayor parte y poner a
cubierto de enemigos a aquella provincia” (1766), Biblioteca de la Academia Nacional de la Historia,
Buenos Aires. We thank Fabrı́cio Prado for drawing our attention to this document. For 1777–1812, see
Borucki, “The Slave Trade to the Rı́o de la Plata.” A few hundred more arrived thereafter, as late as
the 1830s. See IntraAmertoSpanAmer.xlsx for a detailed derivation of our estimates.
32 The French were more likely to buy slaves from the Dutch and English than to sell them to the
Spanish given the dominance of St. Domingue. But during the U.S. War of Independence, particularly
toward the end, French planters could not get their sugar to Europe, and slave prices in St. Domingue
declined temporarily as a result. Unspecified numbers moved to Cuba from 1777 to 1779, then 7,000
from 1781 to 1783, and nearly 5,000 went to Venezuela. Borucki, “Trans-Imperial History in the Making
of the Slave Trade to Venezuela,” 49; Amores, Cuba en la época de Ezpeleta, 129, 134; and http://
slavevoyages.org/tast/database/search.faces?yearFrom⫽1777&yearTo⫽1790&natinimp⫽10 for slave
prices. A doubling of the documented number allows for unrecorded inflows. From 1680 to 1789, the
Danish Islands (St. Croix and St. Thomas) received only 64,300 captives from Africa, and the great
majority were put to work on sugar plantations, the value of whose output was only slightly behind that
of Cuba and Puerto Rico in 1770; Eltis, “The Slave Economies of the Caribbean,” 113. Thus the Danish
Islands could not have supplied large numbers before that year. The O’Malley database has 1,500 captives leaving Danish islands for Spanish colonies before 1790, with destinations centered on Cartagena
before 1710 and Puerto Rico in the 1780s. We estimate 6,000 taken to the Spanish colonies before 1790.
For post-1790, see Svend E. Green-Pedersen, “Colonial Trade under the Danish Flag: A Case Study
of the Danish Slave Trade in Cuba, 1790–1807,” Scandinavian Journal of History 5, no. 1– 4 (1980):
93–120.
33 Only three colonies north of the Rı́o de la Plata received slaves from ports in the Americas between
1790 and 1818—Cuba, Puerto Rico, and Venezuela. We estimate that the first received 60,300, the
second 3,900, and the third 10,000. See Borucki, Eltis, and Wheat, “Notes on the Estimates of the
Intra-American Slave Trade to the Spanish Americas”; IntraAmertoSpanAmer.xlsx; Borucki, “TransImperial History in the Making of the Slave Trade to Venezuela.” The combined total of 74,300 is
distributed across American regions of departure using ratios calculated from the O’Malley database.
This procedure allows us to estimate that 25,300 came from the British Caribbean, 1,900 from St. Eustatius, 41,900 from the Danish Islands, 2,500 from St. Domingue, and 2,700 from Brazil. After 1820,
some English owners moved their slaves illegally to Spanish islands, for which we allow 5,000. Such
activity reportedly created an English-speaking enclave between Holguı́n and Gibara in Cuba in the
1820s. See Great Britain, Parliament, House of Lords, Second Report from the Select Committee of the
House of Lords, Appointed to Consider the Best Means Which Great Britain Can Adopt for the Final Extinction of the African Slave Trade, Parliamentary Papers, 1850, vol. 9, 75–79; also Richard Madden to
James Stephen, Colonial Office, January 1, 1841, BNA, FO313/33, and Attorney General to Foreign
Office, December 2, 1841, ibid. A much smaller movement went from Anguilla and Tortola to Puerto
Rico; see George Grey to Palmerston, November 29, 1835, BNA, FO84/186, and George Canning to
Sir William A’Court, October 24, 1823, FO84/24. To the south, 1,536 captives were removed from Brazilian vessels by Argentine privateers during the Argentine-Brazilian War (1825–1828), some of whom
left from Brazil.

and, most strikingly, more than the whole of the British Caribbean. Of even greater
significance, however, is that in the colonial era in both the Spanish and the British
imperial domains, many times more people came in from Africa than from Europe,
a central demographic point that receives scant recognition in the literature on transatlantic migrations to Latin America.
But can we say more than just “Africans”? What was the ultimate provenance of
these two million captives? The broad pattern is one of heavy reliance on Upper
Guinea and Angola through to the mid-seventeenth century, when the direct link
with Africa prevailed, followed by a remarkable inflow of African peoples and cultures as the intra-American trading routes emerged. The founder generations in the
Caribbean, Mexico, and Peru left overwhelmingly from northern Upper Guinea—
“the Rivers of Guinea” feature strongly in the records, suggesting the coast of modern Guinea-Bissau.34 The first vessel bringing captives directly from elsewhere in
sub-Saharan Africa—actually the first known transatlantic slave ship—sailed from
São Tomé in 1525, and other sixteenth-century voyages from this island would follow,
carrying captives from both Lower Guinea (probably eastern Nigeria) and WestCentral Africa. However, Upper Guinea remained the dominant source until the
early seventeenth century. In the mid-1590s, vessels from what is now Angola supplied the majority of slaves in Veracruz, but in the larger slaving port of Cartagena,
Angola and Upper Guinea accounted for roughly equal shares from about 1590 until
1620. After 1620, close to seven out of ten slave ships arriving in both Cartagena and
Veracruz came from Angola.35 This pattern ended abruptly after 1640, when Dutch
and English slave traders began supplying the Spanish colonies. Both of these slaving
powers had a strong presence on the Gold Coast and the Bight of Benin through to
the early eighteenth century. Thereafter, from 1720 to 1790, almost all bozales—a
term that referred to newly arrived Africans who did not yet speak Spanish or Portuguese or practice Catholicism in ways that Spanish colonists could easily recognize—arrived via Jamaica, the African provenance of whose captives in this era is
well established. It is likely that for 150 years after 1640, three out of four Africans
arriving in the Spanish Americas left from the coast between Elmina in Ghana and
the Cross River in Nigeria.36 Today, no fewer than 716 languages are spoken in the
hinterlands of this most densely populated part of sub-Saharan Africa.37
On the other side of the Atlantic, the African inflow into Mesoamerica diminished after 1640, though occasional arrivals in Mexico are recorded until 1735. Other
Spanish-speaking regions relied on non-Hispanic slave traders sailing from West
Africa. When the Spanish direct trade reemerged—starting slowly in 1792 but growing rapidly after 1808—they not only were able to restore their old links with Upper
Guinea, but drew on the whole range of slave markets from Senegambia in the north

to Mozambique in the southeast (not least because most of their European rivals had
pulled out). Cuba became the main Caribbean buyer of African slaves, and thus
continued the pattern of extreme African diversity established earlier in the rest of
the Spanish possessions. The Spanish had the most mixed African-descended population of any region in the Americas. Rio de Janeiro received 85 percent of its two
million slaves from Luanda and Benguela; half of the large inflow into São Salvador
de Bahia came from the Mina coast (the Gold Coast and the Bight of Benin); a
similar proportion of slaves from St. Domingue left from a region stretching just 250
miles north of the Congo River estuary. Of the major Spanish ports, only the Rı́o
de la Plata’s dependence on Angola is comparable, and perhaps Mexico’s reliance
on the widely separated Guinea and Angola regions given the early end of the slave
trade there. Much of the circum-Caribbean drew from all African provenance zones
except Mozambique.38 Yoruba influence was certainly strong in nineteenth-century
Cuba, but languages based on African elements in Spanish America survived in only
the most remote locations, and can be observed in fragmentary form in the rituals
of modern African-based religions.39 Confraternities and African “nations” in the
Iberian Americas were in the long run inevitably highly syncretic across African
cultures.
The overall diversity of the Spanish Empire’s black population was further increased by mestizaje, which sometimes developed in regions very close to places receiving new slave arrivals. By 1800, 30 percent of the inhabitants of Buenos Aires
were of African ancestry, the large majority of whom had been born in Africa and
were identified as “black” in official documents. However, 800 kilometers northwestward, in the city of Córdoba at the core of modern Argentina, colonial censustakers recorded the majority of the non-white population as pardos, an ambiguous
term referring to people of mixed African, Amerindian, and European ancestry.40
Late-colonial Venezuela had a similar repertoire of colonial casta categories, from
the recently arrived Africans on the coast to the long-established pardos inland.41
Our findings suggest that those toiling in the export sector after 1790 were predominantly African-born, whereas the mainly free populations of mixed ancestry
remained on the fringes of the Atlantic economy—which sometimes led them to
migrate to port cities in search of better prospects.

nearly half a century before Columbus’s landing in 1492. While the Portuguese pioneered early modern European expansion along the coasts of Africa, it is often
forgotten that Spanish mariners and merchants were close behind. During the midand late 1400s, Castilian ships sailed from Andalusia to Upper Guinea, and even as
far as the Mina coast.42 Spanish voyages transported enslaved Africans to the Canary
Islands from the late fifteenth century; not only did these voyages increase in the
1530s, but a small number of them continued to the Americas with their captives,
three decades before the Portuguese began a regular slave trade to Brazil.43
Only Spanish vessels were allowed to enter ports in the Spanish Americas until
1580, at least in theory. Thereafter the union of the Spanish and Portuguese crowns
provided much greater access to Portuguese vessels. In this era (1580–1640), slaving
expeditions were generally organized by merchants in the Iberian Peninsula and in
practice were sometimes Spanish, sometimes Portuguese, and sometimes both.44
Portuguese ships frequently left from a Spanish port, or visited such a port prior to
sailing to Africa, and often our only knowledge of a particular voyage emerges from
Spanish sources, which in this era habitually Hispanicized the names of vessels, their
captains, and sometimes their owners. Thus it is difficult and somewhat anachronistic
to attempt to separate Spanish from Portuguese voyages for the years prior to 1641,
particularly during the era of the Iberian Union. Additionally, there is the question
of the true nationality of the owner of a vessel or venture. How do we label the 1594
venture owned by the Florentine investor Francesco Carletti and his father, Antonio,
who first journeyed to Seville from Florence to obtain a license from the Spanish
authorities and then fitted out their expedition before proceeding first to Upper
Guinea, then to Cartagena, and ultimately to Peru with eighty-nine slaves? Their
vessel certainly sailed under the sanction of the Spanish authorities, as did many
others that were not owned by Spanish subjects, and is counted as such here.45
A parallel situation with different roots existed at the end of the slave trade, when
the Spanish again emerged as major carriers of slaves to their colonies. The Bourbon
reforms that liberalized trade meant that by the early 1790s, Spanish ports in the New
World were effectively open to slave vessels of all nations. At the same time, the
revolution in St. Domingue and the rising demand for plantation produce stemming
from industrialization boosted Spanish American slavery and the slave trade itself.

ports between 1663 and 1674. Though it lasted only eleven years, the Grillo and Lomelı́n asiento exemplifies Spain’s shift away from a reliance on Portuguese slaving networks based in Africa and the
Atlantic Islands, toward Dutch and English networks that could provide captives from their own American slaving outposts such as Curaçao and Jamaica. See Marisa Vega Franco, El tráfico de esclavos con

The initial beneficiaries were British and U.S. slave traders, who from 1790 to 1807
together brought in seven out of every ten transatlantic captives landing in Hispanic
colonies. Merchants of Buenos Aires and Montevideo with trans-imperial networks
stemming from their eighteenth-century links with the Portuguese Colônia do Sacramento became the first to revive Spanish transatlantic slaving. In the fifteen years
after 1790, they introduced two times more slaves directly from Africa into the Americas than did their Cuban-based counterparts.46
Not until the U.S. and the British largely withdrew from the traffic in 1808 did
the Spanish come to dominate the slave trade to their remaining insular colonies.
In the quarter-century after 1810, after all the mainland Spanish American republics
had abolished this traffic, Spanish traders brought 306,000 African captives into
Cuba and Puerto Rico, well over three-quarters of an estimated overall total of
347,000 arrivals in the Spanish Americas from Africa in these years.47 In 1835, facing
extended diplomatic and naval pressure from the British, Spain agreed to a treaty
that allowed British cruisers to detain Spanish vessels suspected of slave-trading
activity even if they had no slaves on board. In response, most Spanish slave merchants registered their vessels under other flags, especially those of Portugal and to
a lesser extent the United States, neither of which had a major naval presence off
West Africa. And when the British imposed similar terms on the Portuguese a few
years later, some Cuban-bound Spanish slave ships began to sail without any registration papers. Overall, however, the pattern of the nationalities of those organizing the massive influx of Africans into the Spanish Americas is clear. After a
transitional period lasting about a decade after 1807 that saw some Spanish merchants acting as fronts for U.S. or British citizens, 90 percent of traders bringing
slaves into Cuba were a mixture of Cuban and Spanish (especially Catalan). They
were born or lived overwhelmingly in Cuba and Puerto Rico, some of them trading
even to Brazil.48
What was the nature of Spanish involvement in the transatlantic trade between
1640 and 1790? For the first twenty-two years of this period—until the establishment
of the Grillo and Lomelı́n asiento in 1662—close to de facto free trade existed in the
Spanish Americas, largely as a consequence of the crisis in Spanish Atlantic commerce.49 The old licensing system collapsed, and while the Spanish managed at least

eleven transatlantic slaving expeditions, sixty-four non-Spanish slave ships (mainly
Portuguese and Dutch) entered Spanish American ports in the same period.50 For
the next twenty-eight years, to 1690, only twenty slaving vessels set out under the
Spanish flag, mostly between 1677 and 1681, an average of less than one a year.51
By contrast, for the seventy-five years from 1691 to 1765, the Voyages database contains only a single transatlantic Spanish voyage. But then, in response to the short
British occupation of Havana (1762–1763), when the British disembarked 3,500
slaves in ten months, the Spanish crown made determined efforts to revive their own
transatlantic slave-trading role. They established the Compañı́a Gaditana and attempted to funnel all slaves destined for the islands and Caribbean mainland ports
through Puerto Rico.52 The company brought an estimated 3,000 slaves into San
Juan between 1766 and 1769, but it was a financial disaster and ceased operations.
Next, the Spanish crown obtained the islands of Fernando Po (now Bioko), Annobón, and Corisco and commercial rights to the mainland between the Niger and
Ogoue Rivers in the Bight of Biafra from Portugal in the 1778 Treaty of El Pardo.
Their attempt to establish slave-trading bases there also resulted in financial disaster
and severe loss of life, with only a few slaves arriving in the Rı́o de la Plata (mainly
from Corisco Island, now part of Equatorial Guinea).53 In 1784, the Spanish crown
contracted with the large Liverpool firm of Baker and Dawson to bring slaves to
Venezuela and Cuba. In the late 1780s, the crown also arranged for Spanish personnel to sail on Baker and Dawson vessels, subcontracted by the Company of the
Philippines to carry slaves to the Rı́o de la Plata. These personnel were expected to
learn the trade and form a pool of skilled labor on which Spanish merchants would
be able to draw to reestablish a strong presence in the transatlantic traffic. This, too,
was unsuccessful. In the twenty years after the Compañı́a Gaditana shut down, only
four Spanish slaving voyages show up in the most recent Voyages database, as opposed to 2,000 British, 1,100 French, and 1,000 Portuguese.54
In two of the major branches of the intra-American slave trade, the Spanish were
hardly any more successful. Dutch merchants dominated the slave traffic through
Curaçao (though Hispanic slave traders were certainly involved), and the Portuguese
played a similar role in the traffic from Brazilian ports to the Rı́o de la Plata from
1585 (just five years after the founding of Buenos Aires) through to 1777 (when the
Spanish conquered Colônia do Sacramento). Thereafter, Spanish American merchants came close to sharing the traffic equally with Luso-Brazilian slave traders.55

Buenos Aires and Montevideo, and the Rı́o de la Plata briefly became the most
important destination for slaves leaving Rio de Janeiro for all secondary markets
(Rio de Janeiro also being a major slave entrepôt).56 Of course, the Spanish were
largely responsible for the now-centuries-long land slave-trading routes connecting
Veracruz, Mexico City, and Acapulco and linking Cartagena with Lima, especially
after the rupture of the Iberian Union and the concomitant withdrawal of Portuguese
merchants.
In the British Caribbean—the largest intra-American market for Hispanic America—Spanish merchants had a larger role. Both the Company of Royal Adventurers
and its successor, the Royal African Company (RAC), usually refused to deliver
slaves to Spanish colonies, though they did sell them to all comers from their factories in Kingston and Bridgetown. Beginning at least as early as 1661, Spanish merchants carried off purchases from Kingston and Bridgetown in their own vessels both
before and after Grillo and Lomelı́n, the first asentistas of the post-1640 system,
began their activities.57 Some English merchants operating outside the RAC’s monopoly did, however, carry slaves into Spanish ports.58 Whole shiploads of enslaved
people newly arrived from Africa were handed over to the Spanish in Kingston and
Bridgetown—so many, in fact, that in 1680 the Jamaican legislature imposed a tax
on slaves traded to foreign colonies.59 The major Spanish figure here was Santiago
Diego del Castillo, a native of Barcelona who eventually became an English subject.
His official title from 1688 was Commissioner-General for the Introduction of Negroes.60 In 1690, when war brought shortages of slaves and high prices in Jamaica,
it was Castillo who organized expeditions from Kingston to Curaçao to relieve the
situation—a Spanish slave trader serving the needs of English planters.61

dominant source for the nearby Spanish colonies, Spanish participation fell away.
When first the Portuguese and then the French assumed the asiento between 1694
and 1713, they drew on English ports and Curaçao without using Spanish intermediaries. More importantly, a huge expansion of the English transatlantic trade began
with the effective curtailment of the RAC monopoly in 1698.62 The London, Bristol,
and Liverpool slave dealers who now entered the trade were much less inhibited than
the RAC about smuggling slaves into Spanish colonies. And for most of the 1713–
1739 period, the South Sea Company could legally bring slaves into Spanish ports.
References to Spanish colonies are abundant in English sources after 1700, but most
slave shippers were not Spanish. The Spanish seaborne slave trade, except for activity
between Spanish ports in the Caribbean and the Pacific, became largely moribund
for nearly a century. Even the twenty-four vessels recorded as bringing slaves from
Africa into Cádiz after 1662 were Dutch or English.63 While the Bourbon reforms
signaled the gradual return of the Spanish to transatlantic slave-trading, their immediate impact was to increase the Spanish presence in the intra-American trade
rather than on the African coast. The years 1790–1810 saw the last great surge of
slave arrivals into Spanish territory from other parts of the Americas (chiefly Rio de
Janeiro, Jamaica, and the Danish West Indies), and one-fifth of Cuban arrivals were
on Spanish vessels.64
We can develop a rough estimate of the Spanish slave trade direct from Africa
following the same intervals that we used to reassess the inflow into the Spanish
Americas. For the earliest era, we have records of 299 transatlantic vessels carrying
an estimated 84,900 slaves. Despite considerable Portuguese participation, we assume that these vessels were all “Spanish” because ships sailing to the Spanish colonies had to first register with Spanish authorities, departing from Seville or other
authorized ports.65 For the Iberian Union—given the impossibility of separating out
Spanish from Portuguese vessels—we follow Mendes in dividing the number of
slaves carried evenly between the two flags. The Spanish portion of this total is
222,500. For the third period, 1641–1789, the most recent Voyages database shows
56 Spanish slave voyages from Africa— 48 of them either in the forty years after the
collapse of the Iberian Union or under the Compañı́a Gaditana in the late 1760s.
Together they disembarked an estimated 15,700 slaves, or fewer than 150 per year.
Even if the actual figure was double this number, the Spanish transatlantic traffic was

operating at trivial levels. In many years, not a single Spanish slave voyage set sail
from Africa.
This pattern changed drastically after 1789. Before 1867, there were only two
years (occurring in wartime in 1805 and 1806) for which there is no record of the
Spanish flag, or at least Spanish owners, in the transatlantic slave trade. Spanish ships
disembarked nearly 10,000 slaves from Africa between 1790 and 1808, several times
greater than the annual pre-1790 flow, but still only one-seventh of total transatlantic
inflows into Spanish colonies. Despite the fact that the revolution in the Rı́o de la
Plata interrupted the regular inflow of slaves in 1812, Spanish deliveries of captives
to America increased nine-fold from 1809 to 1820, to 120,200 captives, almost all of
them taken to Cuba. Initially—say, prior to 1814—many of them arrived on ships
that had Spanish papers but were actually owned or part-owned by citizens of the
United States. But even before the 1820 Piracy Law that made slave-trading a capital
offense, direct U.S. ownership had become unusual, and the Spanish flag accounted
for more than 80 percent of the trade into the Spanish Americas in the second decade
of the century.66 It is hard to imagine anything approaching this expansion without
U.S. and British abolition of the slave trade.67 From 1816 to 1819, the Spanish traffic
appears to have surpassed the previous peak of Spanish slaving, achieved as long ago
as the 1610s and 1620s.
But there was further growth ahead. The Spanish crown declared its Caribbean
colonies closed to the slave trade in the aftermath of the Anglo-Spanish Treaty of
1817, with the ban to take effect in 1820. The volume of arrivals declined sharply
in the early 1820s. But the trade recovered to its former peak briefly in 1827, surpassed previous levels again in the late 1830s, and reached its all-time annual high
in 1859, when Spanish vessels left Africa with an estimated 28,400 captives. Spanish
ships (some of them steam-powered) brought in a total 563,100 Africans in the last
forty-six years of the traffic.
The final column of Table 1 distributes these estimates across the same sixty-year
intervals used for slave arrivals in the Spanish Americas. The U-shaped time profile
of Spanish involvement is not drastically affected by the addition of the intra-Caribbean and Brazil–Rı́o de la Plata trades shown in row 8. The effect is to flatten the
U and make it somewhat more lopsided. Arrivals from foreign colonies in the Spanish Americas did not make up for the decline in traffic direct from Africa between
1640 and 1790. And while flag and ownership data for the intra-American traffic are
scarce, it is unlikely that the Spanish vessels carried as many as half the slaves brought
in from those foreign ports. The time profile of Spanish involvement in the slave
trade (transatlantic and intra-American combined) thus formed a deeper U than the
one that tracks total slave arrivals (again from all sources) into the Spanish Americas.
These patterns help account for the lack of awareness in the Spanish American literature of Spain’s role in the transatlantic slave trade. The sixteenth- and early-

seventeenth-century slave trade to the Spanish colonies is often viewed as something
carried on exclusively by the Portuguese.68 When the transatlantic slave trade was
at its peak in the eighteenth century, Spanish involvement was negligible, and when
this changed in the nineteenth century, the slave trade could be seen as something
that Cubans did, even though the leading slave traders based in Havana after 1820—
Pedro Martinez, Pedro Blanco, and Julián Zulueta—were Spanish by birth and conducted business in both Cuba and Spain.69
Spanish transatlantic slavers disembarked over one million captives in the Americas. Two-thirds of those captives embarked in the nineteenth century, more than
half of them after 1820, or in other words in contravention of Spanish efforts to stop
the slave trade. The Spanish ships carried four times more Africans than did their
U.S. counterparts. When the aggregate total is compared with the transatlantic slave
trades of other empires, we can see that Spain ranks as the fourth-largest slavetrading power overall, not far, in fact, from the third-place French. We do not have
precise figures for the Spanish share of the intra-American trade, but if we did, they
would likely show the Spanish exceeding the contribution of the French—given the
relatively minor role of the latter in carrying captives between ports in the Americas.
For the first few decades and the last sixteen years of the transatlantic slave trade,
Spain was, indeed, the only transatlantic slave-trading empire. Unlike all of their
imperial competitors, the Spanish almost never delivered slaves to foreign territories. By contrast, the British, and the Dutch before them, sold slaves everywhere in
the Americas (with the exception of Brazil in the English case); the French had only
a small slave trade to Cuba in the nineteenth century; Portuguese slave traders were
everywhere outside the British and French Americas. An even more striking feature
of the Spanish trade is that while the Spanish were the most compulsive producers
of official documentation, they were also the most dependent on contraband; thus,
theirs was the only trade that delivered the majority of its captives outside the limits
of the law and official policy as these then stood. Not only was the size of the net
inflow of Africans into Spanish colonies larger than the influx into the British Caribbean, but two-thirds of transatlantic arrivals in the Spanish Empire arrived under
the control of Spanish merchants. Scholars have yet to recognize the scale of Spanish
involvement.

these sites.70 While most of the silver was mined by Amerindians, slaves performed
multiple tasks in mining camps from Zacatecas to Potosı́.71 But the majority of blacks
in Spanish colonies worked in many occupations outside the export sector. Spanish
America had by far the largest urban centers in the Americas. Mexico City, Guanajuato, Querétaro, Lima, Buenos Aires, and Havana were larger than New York,
Boston, and Philadelphia by the turn of the eighteenth century, with the first two
dwarfing all other urban centers throughout the colonial period and beyond.72 Enslaved and free black communities typically performed tasks that provided food,
clothing, shelter, and other services to urban environments.73
More importantly, slaves produced goods that were traded between Spanish colonies. They made textiles in the obrajes of New Spain and Ecuador (some of which
were sold in Manila), and they produced sugar near Veracruz and cacao, flour, tobacco, and hides in Venezuela, all for colonial markets.74 Slaves in coastal Peru
produced wine, wheat, and sugar—essential to Spanish consumers and Spanish culture in the Andes. In Cartagena Province, slaves produced maize, pork, and manatee
lard that were exported to the rest of the Caribbean.75 The Jesuits, perhaps the
largest corporate owner of slaves in the Americas (after the Catholic Church itself),
used almost exclusively African slaves to work farms, cane lands, mines, vineyards,
and textile mills, as well as ranches for cattle, sheep, and mules. The largest Jesuit
estates were in coastal Ecuador, Peru, and Córdoba in modern Argentina, most of
which supplied urban centers from Guayaquil to Potosı́.76 Slaves were concentrated
near the coast, partly because that was where the decline of the indigenous population had been most severe, and partly because of the greater availability of arable
land.77 How did the large cities—located in the highlands and to a lesser extent in
the lowlands—pay for this produce? Silver was a large part of the answer, and here,
too, Africans were involved, given that slaves minted the coins of Potosı́ that facilitated intercolonial trade across South America.

application of slave labor in the Spanish Empire is provided by the British Americas—the Caribbean plus the thirteen mainland colonies.78 Caribbean sugar was the
heart of the British system. Before 1800, the mainland produced only tobacco, rice,
some indigo, and furs that could be sold in Europe, items that never approached
one-quarter of the value of sugar. Yet the British mainland colonies purchased large
quantities of goods from Europe as their populations expanded, and were able to
do so because they sold produce and shipping services to the Caribbean. In the Spanish case, bullion was sugar; the highlands (as the source of a valuable transatlantic
commodity) constituted the counterpart of the Caribbean; an indigenous labor force
filled the role of imported slaves; and the lowlands (Cartagena, Veracruz, coastal
Peru and Ecuador, Venezuela, and the Rı́o de la Plata, among other regions) were
the equivalent of the British American mainland, in that they traded heavily with the
export heartland. Both the British mainland and the Spanish lowland could export
to Britain (tobacco, rice, and indigo) and to Spain (hides, gold, cacao, and pearls),
respectively. But all these items combined could not come close to matching the
value of sugar from the British Caribbean and silver from the Spanish highlands. This
did not matter. Lowland territories in Spanish America were as important to the
highlands as the British American mainland was to the British Caribbean. Indeed,
some Spanish lowland jurisdictions exerted direct administrative authority over highland regions (Lima and later Buenos Aires). Perhaps much of both the Spanish lowlands and the British mainland north of Virginia would have had little beyond subsistence agriculture without their connections to the silver and sugar sectors. The
ability of both the Spanish lowlands and the British North American mainland to
import transatlantic commodities (including slaves) hinged on the ability of these two
areas to sell their produce to the rest of their respective imperial systems. Yet Spanish intercolonial exchange and relations have attracted much less scholarly attention
than has trade between British colonies, and the central role of the Spanish colonies
in Atlantic history after 1640 is still largely ignored.79
All parts of the Americas (except, briefly, for Georgia) were prepared to buy
African slaves prior to the early nineteenth century—if they could afford them.80
Slaves were cheapest in Brazil and in the Caribbean (both islands and littoral), more
expensive on the North American mainland, and more expensive again in Potosı́—
the source of silver that tied together markets in Buenos Aires, Lima, and Cartagena,
and formed the key axis (in terms of value) of the early modern Atlantic economy.

in Cuba and Venezuela, as well as from Peru to Buenos Aires, made it easier to
purchase slaves in the recipient areas during the eighteenth century.81 On the British
mainland, the natural growth of black populations had begun by 1730, and by the
early nineteenth century, Africa seemed less important as a source of labor than it
had once been. For the Spanish American highlands, the equivalent was the reappearance of a positive rate of growth among indigenous peoples and mestizaje in the
late seventeenth century after nearly two centuries of sharp decline. As a consequence, by the mid-eighteenth century, coerced Indian labor had declined even in
Potosı́, and mining operations were conducted mostly on the basis of waged labor.
Black slaves could be found in most Spanish American colonies. Where they were
fewer in number, for example in Central America, mid-eighteenth-century Appalachia, and rural New England (outside Rhode Island), it was usually an indication
of relative poverty and lower levels of intercolonial commerce.82
Africans were among the very first arrivals to disembark from the Old World, but
at the point of contact no one could have anticipated a transatlantic slave trade from
Africa. In the early years of Spanish colonization, the Spanish may have carried more
Amerindian slaves east than African slaves west, and the latter left not from Africa
itself but rather from Spain (the first known slave voyage direct from Africa did not
disembark until 1525). Furthermore, within the colonial Spanish Americas, each of
the three major founder populations—Amerindians, sub-Saharan Africans, and Iberians—came to be associated with different terms of labor. Beyond the circum-Caribbean and the Rı́o de la Plata, forced indigenous labor extracted via the encomienda and repartimiento (or mita) systems sustained both private obrajes and public
works into the eighteenth century. Indigenous population densities combined with
Spanish takeover of preexisting Amerindian imperial structures facilitated this process. Intermittent forced labor was not, however, enslavement. Slavery, a second
labor regime, was, after the early decades, mostly reserved for Africans—the largest
transoceanic immigrant group. Not much is known about the terms of either migration or labor of the third group—Europeans. They were to be found among galley
slaves in sixteenth-century Havana, Santo Domingo, and Cartagena, but the Spanish
shared the general European aversion to enslaving other Europeans (unless they
were Moriscos or Muslims).83 No evidence of indentured servants among the halfmillion arrivals from Spain before 1660 has surfaced, but to describe Spanish immigrants as “free labor” is hardly correct. Most were dependents or retainers, rather
than soldiers, bureaucrats, or merchants with obligations extending beyond the provision of labor. If less challenging than enslaved Africans’ struggles to gain their
freedom, the ultimate goals of Spanish migrants were similar in that they, too, hoped

to establish their independence in the Americas and re-create as much of what was
familiar from the Old World as possible.84
From an African perspective, for a century from around 1550, several of Spain’s
circum-Caribbean colonies would have been predominantly black long before the
development of the export sugar complex. More Africans than Europeans arrived
in this broad region, as well as along the Pacific coast from Panama to Lima, before
1600. The influence of various Upper Guinea and West-Central African cultures on
the circum-Caribbean between the sixteenth century and the early seventeenth century can now only be imagined. After the mid-seventeenth century, however, Africans arriving in any Spanish colony were likely to find themselves in a minority, with
the larger society usually comprising Amerindians, Peninsular and criollo Spaniards,
their mestizo progeny, and a growing native (creole) population of full and mixed
African ancestry. There were significant black populations in Mexico City and on the
Mexican coasts, on the Pacific and Caribbean shores of Colombia, in coastal Ecuador
and Peru, and in Caribbean Venezuela—regions where the Amerindian population
had largely been decimated after contact. Nevertheless, the dispersal of captives over
an immense geographic area, and the fact that their arrival occurred over a much
longer time span than in any other major polity in the Americas, may have inhibited
the emergence of both large and permanent regions of black demographic and cultural dominance during the three centuries of Spanish colonialism.
Our research also suggests certain implications for the histories of those born to
African parents in the Spanish Americas. A positive rate of intrinsic natural growth
for people of full and mixed African ancestry probably emerged in Mexico before
the United States—perhaps as early as 1650. Intrinsic natural growth rates were also
positive for blacks even at the height of the later Cuban sugar boom.85 Diminishing
slave arrivals were one of the factors behind Mexican mestizaje. People of mixed
origins became more common than those of full African ancestry after 1700, just as
free people of color outnumbered slaves as early as 1680 in some regions. When the
mainland colonies began to loosen ties with Spain, two opposite but related processes
had already been unfolding: first, the formation of African-descended populations
in Mexico and elsewhere that hardly fit modern U.S. understandings of “blackness”
and “whiteness,” and second, the rise of slave arrivals in Cuba, Venezuela, and the
Rı́o de la Plata, renewing direct links with Africa. Coastal Peru, particularly Lima,
saw a combination of the two patterns as Peru underwent centuries of mestizaje yet
received new slave arrivals through the Rı́o de la Plata in the late colonial era. As
with Mexico, the large majority of Peru’s population was of full and mixed Amerindian ancestry. Venezuela received a very significant flow of slave arrivals during

its last thirty years as a colony. Yet, free pardos—people of mixed African, European,
and Amerindian origin—formed the majority of the Venezuelan population by 1810.
Growing majorities of people of mixed ancestry emerged before the Africanization
process triggered by these revived African inflows. The long view suggests that population growth due to mestizaje plus recovery from the virgin soil epidemics of the
early period enabled Spanish America to remain the most populous imperial domain
until late in the colonial era.
Demographics provide no more than an outline of the African presence, however.
In late-eighteenth-century Cuba and the Rı́o de la Plata, a surge of African arrivals
interacted with a growing free African and African-descended population living in
Havana, Buenos Aires, and Montevideo. This encounter led to the expansion (and
reshaping) of African-based associations and black urban culture.86 Africans and
their descendants formed black confraternities in cities from Mexico to Lima, under
the umbrella of the Catholic Church, from the earliest times through to the eighteenth century. Better documentation from the late eighteenth century enables us
to see the emergence of cabildos de nación and “African nations” in Cuba and the
Rı́o de la Plata, respectively, that were not as directly controlled by the Church. Their
functions were very similar to those of the old black confraternities and included the
rituals of life (particularly funerals), socialization, and mutual support. In Cuba,
adherents of Oyo-centric socio-religious groupings such as Sango emerged, and the
tensions between the founding members of the organization and the large numbers
of new arrivals from Africa after 1817 can now be laid out in some detail. The influences of African origins and the Catholic Church on these new associations are
obvious, but so are many syncretic practices, the meaning of which is a matter of
scholarly debate. Black socialization and distinctive African-based cultural practices
are at least very clear. Free and enslaved populations of African ancestry mingled
in these associations, though the leaders were usually free blacks. Free people of
color were essential, since they could own real estate (for example, the house of the
association), they had more time to devote to group activities, and in Spanish America they could represent black associations and defend them against colonial authorities. There is much less evidence of black organizations, and indeed public celebrations such as the Day of Kings, in the British, Dutch, and French Americas,
probably because urban environments were of less relative importance there. The
activities of such groups in other traditionally black cities of the Spanish Atlantic,
such as Cartagena and Caracas, await historians’ attention.
The breadth, diversity, and chronological expanse of the Spanish colonies make
the slave trade to Spanish America very difficult to address. The subdivision of this
field into national Spanish American historiographies makes the subject even more
complex. Additionally, an immersion in the literature of the British, Luso-Brazilian,
Dutch, and French slave trades is essential if we are to understand the Spanish traffic.
In recent years, the historiographies of the transatlantic slave trade, on the one hand,
and colonial Spanish America, on the other, have not seriously engaged with each

91 In this essay we have of necessity focused on ports and broad regions from which slaves were
embarked and disembarked. Sources from the Catholic Church, notarial records, censuses, court cases,
and other colonial documents offer keys to understand the many meanings of African “nations” for
Africans as well as for the bureaucrats and priests who created the files. Future scholarship will integrate
the numerous local studies based on these sources with our new data to refine the debate on African
origins and black identities. The locally based but Atlantic-focused scholarship on Africans and their
descendants in colonial Spanish America is expanding rapidly. For a survey, see Rachel Sarah O’Toole,

other. Scholarship on the slave trade is mostly Anglophone and Francophone and
tends to foreground Northwestern Europe, the North Atlantic, and the United
States, including the non-Hispanic Caribbean. More recently, scholars have moved
the Lusophone world to center stage.87 While many new studies of slavery and the
peoples of African ancestry in Spanish America have appeared, this new scholarship
does not yet embrace the methods and perspectives now used by scholars of the
transatlantic slave trade. Contributions to the history of people of African ancestry
in colonial Spanish America still do not explain how the founder populations got
there.88 Not a single monograph or even article on the slave trade to Mexico has
appeared since the partial treatment in Colin Palmer’s work.89 For countries such
as Peru, Venezuela, Colombia, and Ecuador, scholars have yet to fully exploit the
abundant documentary sources on the connections with Africa. And very little is
known of the Africans shipped to Iberia, the Canary Islands, and the Philippines
during and after the Iberian Union.90 We hope that our research will be the beginning of a coordinated effort to recover the stories of what is the least-known large
branch of the African diaspora.91
