With the Soviet Union firmly in control of the region, the conflict over the region died down for several decades until the beginning of the dissolution of the Soviet Union in the late 1980s and early 1990s, when the question of Nagorno-Karabakh re-emerged. Accusing the Azerbaijani SSR government of conducting forced Azerification of the region, the majority Armenian population, with ideological and material support from the Armenian SSR, started a movement to have the autonomous oblast transferred to the Armenian SSR. In August 1987, Karabakh Armenians sent a petition for union with Armenia with tens of thousands of signatures to Moscow.
