Born and raised in Georgia, Ordzhonikidze joined the Bolsheviks at an early age and quickly rose within the ranks to become an important figure within the group. Arrested and imprisoned several times by the Russian police, he was in Siberian exile when the February Revolution began in 1917. Returning from exile, Ordzhonikidze took part in the October Revolution that brought the Bolsheviks to power. During the subsequent Civil War he played an active role as the leading Bolshevik in the Caucasus, overseeing the invasions of Azerbaijan, Armenia, and Georgia. He backed their union into the Transcaucasian Socialist Federative Soviet Republic (TSFSR), which helped form the Soviet Union in 1922, and served as the First Secretary of the TSFSR until 1926.
