Context: The Nagorno-Karabakh Autonomous Oblast ("Lernayin arabai Inknavar Marz, LIM") was an autonomous oblast within the borders of the Azerbaijan Soviet Socialist Republic, mostly inhabited by ethnic Armenians.

As a result, the Nagorno-Karabakh Autonomous Oblast was established with the Azerbaijan Soviet Socialist Republic on July 7, 1923. According to Karl R. DeRouen it was created as an enclave so that a narrow strip of land would separate it from Armenia proper. According to Audrey L.
