Azerbaijan, officially the Republic of Azerbaijan, is the largest country in the Caucasus region located at the crossroads of Western Asia and Eastern Europe, it is bounded by the Caspian Sea to the east, Russia to the north, Georgia to the northwest, Armenia to the west, and Iran to the south.
The exclave of Nakhchivan is bounded by Armenia to the north and east, Iran to the south and west, while having a short borderline with Turkey to the northwest.
Azerbaijan has an ancient and historic cultural heritage, including the distinction of being the first Muslim-majority country to have operas, theater and plays. The Azerbaijan Democratic Republic was established in 1918, but was incorporated into the Soviet Union in 1920.
Azerbaijan regained independence in 1991. Shortly thereafter, during the Nagorno-Karabakh War, neighboring Armenia occupied Nagorno-Karabakh, its surrounding territories and the enclaves of Karki, Yukhary Askipara, Barkhudarly and Sofulu. The Nagorno-Karabakh Republic, which emerged in Nagorno-Karabakh, continues to be not diplomatically recognized by any nation and the region is still considered a de jure part of Azerbaijan, despite being de facto independent since the end of the war.
Azerbaijan is a unitary constitutional republic, although no opposition parties have representation in parliament, and international NGOs have criticized Azerbaijan's human rights record. It is one of the six independent Turkic states as well as an active member of the Turkic Council and the TÜRKSOY community.
Azerbaijan has diplomatic relations with 158 countries and holds membership in 38 international organizations. It is one of the founding members of GUAM, the Commonwealth of Independent States (CIS) and Organization for the Prohibition of Chemical Weapons.
The Constitution of Azerbaijan does not declare an official religion, and all major political forces in the country are secular nationalist, but the majority of people and some opposition movements adhere to Shia Islam. Relative to other Eastern European and CIS states, Azerbaijan has reached a high level of human development, economic development and literacy, as well as a low rate of unemployment and intentional homicide.
