The Russian Revolution that led to the establishment of a communist government occurred in 1917. It included two significant events: the February Revolution, which resulted in the abdication of Tsar Nicholas II, and the October Revolution, where the Bolshevik Party, led by Vladimir Lenin, seized power. The February Revolution initiated a provisional government but failed to address ongoing social and economic issues. The more radical October Revolution resulted in the establishment of the Soviet government and the withdrawal from World War I. This marked the beginning of communist rule in Russia and had profound impacts on global politics for the century to follow.
