Formation of the USSR

The Union of Soviet Socialist Republics was established, uniting multiple Soviet republics into a single entity. This union was a significant political shift following the Russian Revolution and the subsequent Civil War. Bolshevik leader Vladimir Lenin played a crucial role in the formation, advocating for a centralized socialist republic that would encompass various nationalities under a communist government. The establishment of the USSR represented the culmination of efforts to create a federation of socialist republics that adhered to Marxist principles, marking a pivotal moment in world history.
