The conflict between Georgian and Ossetians dates back until at least 1918. In the aftermath of the Russian Revolution, Georgia declared independence (26 May 1918) under Mensheviks, while the Bolsheviks took control of Russia. Georgians suppressed a peasant rebellion in the current South Ossetia with great severity in 1918 and in the next year outlawed the National Soviet of South Ossetia and refused to grant autonomy to the region. In June 1920, a Russian-sponsored Ossetian force attacked the Georgian Army and People's Guard. The Georgians responded vigorously and defeated the insurgents, with several Ossetian villages being burnt down and 20,000 Ossetians displaced in Soviet Russia. Eight months later, the Red Army successfully invaded Georgia.
