Autonomy without settlement

The Nagorno-Karabakh Autonomous Oblast was created in 1923 after the Caucasian Bureau decision and the implementing NKAO formation decree. It placed the Armenian-majority mountain districts inside the Azerbaijan SSR rather than the Armenian SSR, while leaving the Lachin and Kelbajar approaches outside the autonomous boundary. Arsene Saparov treats this as a Soviet solution to contiguity, oil, Turkish diplomacy and local power, not as a neutral ethnographic exercise Saparov. sourced opinion

The census line is the key to the NKAO page. In the early 1920s Armenians formed an overwhelming majority in the oblast. By 1989 they still formed more than three quarters of the population, while Azerbaijanis formed a little over one fifth 1989 census. Armenian politics read that persistence as proof that the oblast's population never consented to Azerbaijani sovereignty. Azerbaijani politics read the same period through constitutional legality: the oblast was autonomous, not sovereign, and its borders were internal Soviet administrative borders. contested

Autonomy also failed at the level of trust. Armenian accounts stress school, investment, appointment and language grievances, culminating in the 20 February 1988 vote asking for transfer to Armenia. Azerbaijani accounts stress the danger that ethnic majority would be used to dismember a union republic. Both claims contain real legal and political content, but the institutional design could not absorb them once Soviet coercive power weakened. editorial The result was a place created to contain a dispute becoming the administrative map through which the First Karabakh War was fought.
