Cause

The October Revolution of 1917 destabilized the former Russian Empire, prompting Ukraine to declare independence as the Ukrainian People's Republic. Lenin responded by dispatching Antonov's expeditionary group to Ukraine and Southern Russia, seeking to extend Bolshevik control over the region and its resources, thus igniting armed conflict between the new Soviet government and the nascent Ukrainian state.

Event

Between 1917 and 1921, the Ukrainian People's Republic fought the Bolsheviks (Russian SFSR and Ukrainian SSR) in a multi-front war complicated by the simultaneous involvement of the Revolutionary Insurgent Army of Ukraine, the White Army, and the forces of Poland, Germany, and Austria-Hungary. The conflict involved shifting alliances and front lines across the territory of present-day Ukraine.

Consequence

The Bolsheviks emerged victorious, incorporating Ukraine into what would become the Soviet Union. Modern Ukrainian historians view the outcome as a failed war of independence, while Soviet historiography framed it as liberation from foreign occupation. The war foreclosed Ukrainian statehood for decades and shaped the political and cultural relationship between Ukraine and Russia throughout the twentieth century.
