However this geopolitical position caused deep problems throughout the history. Thus, Azerbaijan was separated between Russia and Iran in 1813 and 1828 according to the Gulustan and Turkmenchay contracts, relevantly. Therefore Azerbaijan territories started to be named Southern and Northern Azerbaijan. After the Bolshevik revolution, Azerbaijan Democratic Republic was established in 28 May 1918. However Azerbaijan was invaded by the Russian troops in 27 April 1920. Azerbaijan became the part of USSR in 1922 and named “Azerbaijan Soviet Socialist Republic” from 1936. Eventually northern Azerbaijan, which was the colony of USSR, declared independence in 1991, after the collapse of the Soviet Union. The most important trade relationships were realized via the Mediterranean and Black Seas in ancient times and medieval. The caravan routes, especially Great Silk Way were extended from China and India to Mediterranean and Black Seas and crossed Azerbaijan. Well-known caravan route which made connection between Eastern Europe and South Caucasus, Iran, and Central Asia via Darband passage also crossed Azerbaijan. The social and political processes, started in 1980s, resulted with the collapse of the USSR, and all union republics became independent. Azerbaijan was one of the first countries, which gained independence in those years. Azerbaijan declared independence on 18th of October 1991. Thus Azerbaijan became one of the countries, which balances economic and political relationships in the region. This characteristic comes from the geopolitical position of Azerbaijan. Located in the region of the Southern Caucasus, Azerbaijan has borders with the Caspian Sea to the east, Georgia and Russia to the north, Iran to the South, and Armenia to the southwest and west. A small part of Nakhchivan Autonomous Republic also has borders Turkey to the northwest. The transition period was observed some problems in Azerbaijan. However the country could maintain the independence. To do so, several economic, social and political problems were resolved. The main problems, which Azerbaijan confronted, were structural. Therefore it was important to create economy, which can manage itself independently. Throughout the years, some important steps have been taken in order to liberalize the economy. Azerbaijan has huge natural resources, which triggered the development of economy. Oil and gas resources are the most important wealth of Azerbaijan. In 2015, 90% of the export belongs to the energy carriers. This figure also shows the importance of the energy sector in Azerbaijan economy. For this reason, energy resources should be used relevantly. Thus, abovementioned international caravan routes attracted the other countries from ancient times. Azerbaijan played “Golden Bridge” role in the region. The economic development of Azerbaijan is consisted of three important parts after the independence. The period before the independence, and the transition period, accompanied with three various parts will be analyzed.
