The Red Army invasion of Armenia was a military campaign which was carried out by the 11th Army of Soviet Russia from September to 2 December 1920 in order to install a new Soviet government in the First Republic of Armenia, a former territory of the Russian Empire. The invasion coincided with an invasion by Kemalist Turkey and anti-government insurrections organized by local Armenian Bolsheviks. The invasion led to the dissolution of the First Republic of Armenia and the establishment of the Armenian Soviet Socialist Republic. Militant resistance continued in southern Armenia under Nzhdeh's self-declared Republic of Mountainous Armenia until July 1921.
