During the period of the USSR, Stepanakert served as the capital of the Nagorno-Karabakh Autonomous Oblast within the Azerbaijani Soviet Socialist Republic, between 1923 and 1991. With the self-declared independence of Artsakh in 1991, Stepanakert continued with its status as the political and cultural centre of the newly established republic, being home to all the national institutions: the Government House, the National Assembly, the Presidential Palace, the Constitutional Court, all ministries, judicial bodies and other government organizations.
