In July 7 in 1923 on the one part of Nagorno Karabakh was established Nagorno-Karabakh Autonomous Region (NKAR). In 1923 population of NKAR was 157,800. During 60 years of existence of NKAR, people of Artsakh were being obeyed to different limitations. As a result of this the Armenian population of 85 villages deprived of their homes. Decreased also specific number of Armenians (in 1926- 93,5% Armenian, in 1989- 77% Armenian). in The late 80 entension of national-liberation movements in USSR the policy of "reconstruction" couldn't affect on the question of Nagorno Karabakh. The Armenians of Artsakh again raised the issue of Nagorno Karabakh. The government of Azerbaijan had for an object to deprive Armenians of NKAR from their homes. In february 20 in 1988 convenes session of regional Council of NKAR approved a motion to apply to the Supreme Councils of Azerbaijan SSR, Armenian SSR and USSR about withdraing NKAR from the Azerbaijan and joining it to Armenia. But both Baku and Moscow declared that it is impossible. Center, in spite of appeals of democracy, "Reconstruction" and publicity, initially was in a negative position, so that national movement doesn't affect to another republics. Kremlin Started represent "issue of Nagorno Karabakh" not political, but economic problem. It isn't occasional that in March in 1988 by the decision of CRSU Central Committee (The Soviet Union's Communist Party Central Committee_ Council of Ministers of USSR 400 million ruble was provided to NKAR to solve social-economic problems of that region.But Azerbaijani government used that many for development of Azerbaijani settlements of Nagorno Karabakh. For stopping the movement Azerbaijani government was subjected to blockade of Nagorno Karabakh, which arranged the social-economic situation in the region.
To stabilize the situation in the region, in Stepanakert was invited Congress,which declared to restore Soviet Government and the Regional Committee.In the same time it was decided to pass the governance of region to the National Council elected by them (Congress). The existence of National Council of Nagorno Karabakh was not profitable neither for Azerbaijan nor for Central Authorities.
