This decision was taken without local deliberation or plebiscite. As a result, the Nagorno-Karabakh Autonomous Oblast (NKAO) was established within the Azerbaijan SSR in 1923. Most of the decisions on the transfer of the territories, and the establishment of new autonomous entities, were made under pressure from Stalin. Armenians still blame him for this decision, made against their national interests. For 65 years of the NKAO's existence, the Karabakh Armenians felt they were restricted by Azerbaijan. Armenian discontent stemmed from Azerbaijan severing ties between the oblast and Armenia and pursuing a policy of cultural de-Armenization, planned Azeri settlement, squeezing the Armenian population out of the NKAO and neglecting its economic needs. The census of 1979 showed 162,200 inhabitants of Nagorno-Karabakh Autonomous Region, of whom 123,100 Armenians (75.9%) and 37,300 Azerbaijani (22.9%). Armenians compared this to the data from 1923 — 94% Armenian. In addition they noted that "as of 1980 in Nagorno-Karabakh 85 Armenian villages (30%) have been liquidated and no Azerbaijani villages at all." Armenians also accused the government of Azerbaijan of a “purposeful policy of discrimination and replacement". They believed that Baku's plan was to supersede absolutely all Armenians from Nagorno-Karabakh. Azerbaijani residents of the NKAO, meanwhile, complained of discrimination by the Armenian majority of the autonomous oblast and of economic marginalization. Thomas De Waal in his ‘’Black Garden’’ points out that NKAO was economically worse off than Armenia SSR. However, he noted elsewhere, economically Azerbaijan SSR overall had the most poverty in the South Caucasus. Nevertheless, NKAO's economic indicators were better than Azerbaijan's as a whole, a possible motivation for Karabakh Armenians to join Armenia SSR. When the dissolution of the Soviet Union began in the late 1980s and early 1990s, the question of Nagorno-Karabakh re-emerged. On February 20, 1988, the Oblast Soviet of the NKAO weighed up the results of an unofficial referendum on the reattachment of Nagorno-Karabakh to Armenia, held in the form of a petition signed by 80,000 people. On the basis of that referendum, the Oblast Soviet of Nagorno-Karabakh adopted appeals to the Supreme Soviets of the USSR, Azerbaijan, and Armenia, asking them to authorize the secession of Karabakh from Azerbaijan and its attachment to Armenia. It caused indignation among the neighboring Azerbaijan population, which began to gather in crowds to go and "put things in order" in Nagorno-Karabakh. On February 24, 1988, a direct confrontation occurred on the border of Nagorno-Karabakh near
