Deportation of Azerbaijanis from Armenia

Mass deportation of Azerbaijanis from Armenia took place several times throughout the 20th century, and sometimes some of them have been described by some authors as acts of forced resettlement and ethnic cleansing.

Prior to the October Revolution, Azerbaijanis had made up 43 percent of the population of Yerevan. The Tartar (i.e. Azerbaijani) population endured a process of forced migration from the territory of the First Republic of Armenia and later in the Armenian SSR several times during the 20th century. Under Stalin's policies, approximately 100,000 Azerbaijanis were deported from the Armenian SSR in 1948. Their houses were subsequently inhabited by Armenian repatriates who arrived in the Soviet Union from abroad.

Azerbaijanis continued to live in the Armenian SSR until the outbreak of the Nagorno-Karabakh conflict in 1988–89, when practically all Azerbaijanis in Armenia left or were expelled concurrently with the expulsion/flight of Armenians from Azerbaijan. The deportation was done largely without bloodshed and it was partially in response to Armenians being forced out of Azerbaijan; it was also the last phase of the gradual homogenization of the Armenian republic under Soviet rule.
