The Soviet Georgian government, established after the Red Army invasion of Georgia in 1921, created an autonomous administrative unit for Transcaucasian Ossetians in April 1922 under pressure from Kavbiuro (the Caucasian Bureau of the Central Committee of the Russian Communist Party), called the South Ossetian Autonomous Oblast (AO). Some believe that the Bolsheviks granted this autonomy to the Ossetians in exchange for their help in fighting the Democratic Republic of Georgia and favoring local separatists, since this area had never been a separate entity prior to the Russian invasion. The drawing of administrative boundaries of the South Ossetian AO was quite a complicated process. Many Georgian villages were included within the South Ossetian AO despite numerous protests by the Georgian population. While the city of Tskhinvali did not have a majority Ossetian population, it was made the capital of the South Ossetian AO. In addition to parts of Gori Uyezd and Dusheti Uyezd of Tiflis Governorate, parts of Racha Uyezd of Kutaisi Governorate (western Georgia) were also included within the South Ossetian AO. All these territories historically had been indigenous Georgian lands.
