[1] Ossetian migration to the Georgian regions began in the 13th and 14th centuries and is believed to be connected to the fall of Kingdom of Alania in the North Caucasus to the Mongols and later to Timur's armies.
[2][4] In the 17th century, under pressure from the Kabardian princes, Ossetians started a second wave of migration from the North Caucasus to the Kingdom of Kartli.
[6] Following the breakdown of the Tsarist regime in Russia, Ossetians allied with the Russian Bolsheviks, fighting a war against the newly independent Menshevik Georgia.
In 1922 South Ossetian Autonomous Oblast was established within the Georgian Soviet Socialist Republic (SOAO) by the Soviet administration under pressure from Kavburo (the Caucasian Bureau of the Central Committee of the Russian Communist Party).
[7] It is believed that the SAOA was established by central Soviet government in exchange for Ossetian loyalty and support of Russian Bolsheviks in their fight against Georgian Mensheviks.
