The Russian Revolution consisted of two major events in 1917: the February Revolution, which overthrew the Tsarist autocracy, and the October Revolution (occurring in November in the Gregorian calendar), in which the Bolshevik party, led by Vladimir Lenin, seized power. The revolution was driven by widespread exhaustion from World War I, food shortages, and centuries of social inequality. The Bolsheviks promised 'Peace, Land, and Bread,' appealing to the war-weary soldiers and peasantry. Their victory led to the creation of the Soviet Union (USSR), the world’s first socialist state. This event reshaped global geopolitics for the next 70 years, initiating a worldwide ideological struggle between communism and capitalism. It also resulted in a brutal civil war and the radical reorganization of Russian society, including the nationalization of industry and the redistribution of land.
