Following the Russian revolution, the area of modern South Ossetia became part of the Democratic Republic of Georgia. In 1918, conflict began between the landless Ossetian peasants living in Shida Kartli (Interior Georgia), who were influenced by Bolshevism and demanded ownership of the lands they worked, and the Menshevik government backed ethnic Georgian aristocrats, who were legal owners. Although the Ossetians were initially discontented with the economic policies of the central government, the tension soon transformed into ethnic conflict. The first Ossetian rebellion began February 1, 1918, when three Georgian princes were killed and their land was seized by the Ossetians. The central government of Tiflis retaliated by sending the National Guard to the area. However, the Georgian unit retreated after they had engaged the Ossetians. Ossetian rebels then proceeded to occupy the town of Tskhinvali and began attacking ethnic Georgian civilian population. During uprisings in 1919 and 1920, the Ossetians were covertly supported by Soviet Russia, but even so, were defeated. Between 3,000 and 7,000 Ossetians were killed during the crushing of the 1920 uprising; according to Ossetian sources ensuing hunger and epidemics were the causes of death of more than 13,000 people.
