The political and economic reforms that General Secretary Mikhail Gorbachev undertook in 1985 saw a marked decentralization of Soviet authority. Armenians, in both the Armenian SSR and Nagorno-Karabakh, viewed Gorbachev's reform program as an opportunity to unite the two together. On 20 February 1988, tens of thousands of Armenians gathered to demonstrate in Stepanakert's Lenin Square (now Renaissance Square) to demand that the region be joined to Armenia. On the same day, the Supreme Soviet of Nagorno-Karabakh voted to join the Armenian SSR, a move strongly opposed by the Soviet Azerbaijani authorities.
