The revolution that led to the establishment of the first socialist state in Russia was the October Revolution of 1917. Also known as the Bolshevik Revolution, it was a pivotal event in which the Bolshevik Party, led by Vladimir Lenin, overthrew the Provisional Government established after the February Revolution earlier that year. The October Revolution aimed to dismantle the existing capitalist system and implement a socialist state based on Marxist principles. It resulted in the creation of the Russian Soviet Federative Socialist Republic, which eventually became part of the Soviet Union, significantly influencing global politics and introducing communist regimes worldwide.
