The 1907 Tiflis bank robbery, also known as the Erivansky Square expropriation, was an armed robbery on 26 June 1907[a] in the city of Tiflis in the Tiflis Governorate in the Caucasus Viceroyalty of the Russian Empire. A Bolshevik group "expropriated" a bank cash shipment to fund their revolutionary activities. The robbers attacked a bank stagecoach, and the surrounding police and soldiers, using bombs and guns while the stagecoach was transporting money through Erivansky Square between the post office and the Tiflis branch of the State Bank of the Russian Empire. The attack killed forty people and injured fifty others, according to official archive documents. The robbers escaped with 241,000 rubles.

Vladimir Ilyich Ulyanov, better known as Vladimir Lenin, was a Russian revolutionary, politician, and political theorist. He served as the first and founding head of government of the Russian Soviet Federative Socialist Republic from 1917 until his death in 1924, and of the Soviet Union from 1922 until his death. Under his administration, Russia, and later the Soviet Union, became a one-party socialist state governed by the Communist Party. Ideologically a Marxist, his developments to the ideology are called Leninism.
