The Soviet Decision of 1921 and the Creation of Nagorno-Karabakh Autonomy

One of the most important turning points in the modern history of the conflict occurred in July 1921.

The Caucasian Bureau of the Russian Communist Party considered the territorial status of Nagorno-Karabakh. Its proceedings included a decision on July 4 favoring attachment to Soviet Armenia, followed on July 5 by a decision to retain Nagorno-Karabakh within Soviet Azerbaijan while providing broad regional autonomy.

The reasons behind this reversal have been debated extensively by historians. Regional economic relationships, transport connections, Soviet nationality policy, political calculations, and wider strategic considerations all figured in interpretations of the decision.

A common popular claim that Joseph Stalin personally and unilaterally gave Karabakh to Azerbaijan oversimplifies the documented institutional process, although Stalin's position within the Soviet leadership and the political context of the decision remain relevant.

In 1923, the Soviet authorities established the Nagorno-Karabakh Autonomous Oblast within the Azerbaijan Soviet Socialist Republic.

Its administrative center was Stepanakert, previously known as Khankendi.

The autonomous oblast had an Armenian majority. According to the 1926 Soviet census, Armenians represented approximately 89% of its population, while Azerbaijanis accounted for about 10%.

Over subsequent decades, the population composition changed, although Armenians remained the majority.

Soviet governance and Armenian grievances

The Soviet system formally recognized certain cultural and linguistic rights while retaining central political control.

Armenian residents of Nagorno-Karabakh maintained schools, cultural institutions, and religious traditions, but Armenian intellectuals and political activists periodically complained of discrimination, inadequate investment, demographic policies, and obstacles to closer cultural and economic integration with Soviet Armenia.

Azerbaijani officials rejected many of these accusations and emphasized the region's development under Azerbaijani administration.

Petitions seeking the transfer of Nagorno-Karabakh to Soviet Armenia appeared at different points during the Soviet period, including during the Khrushchev era and in the 1970s.

These appeals did not produce a change in territorial status.

Soviet authoritarianism suppressed open nationalist mobilization, but it did not eliminate competing historical narratives or political grievances.

By the late 1980s, the conditions that had kept the dispute contained were beginning to disappear.
