Step-by-step explanation:
Key Figures of the Russian Revolution
The Russian Revolution was a period of political and social upheaval that led to the end of the Romanov dynasty and the rise of the Soviet Union. Three key figures of the Russian Revolution were Vladimir Lenin, Alexander Kerensky, and Leon Trotsky. Lenin was the leader of the Bolshevik Party who masterminded the overthrow of the provisional government and was the architect of the Soviet state. Kerensky led the provisional government after the abdication of Tsar Nicholas II but was eventually overthrown by the Bolsheviks. Trotsky, as a Bolshevik leader and founder of the Red Army, played a crucial role in the eventual victory of the Bolsheviks in the Civil War.
The revolution began in earnest after long-standing problems in Russia were exacerbated by the losses of World War I, leading to Tsar Nicholas II's abdication. The Bolsheviks, who had promised "peace, land, and bread", gained popularity with their ideology to end the war and address the needs of workers and peasants. Lenin's concept of the "vanguard party" was essential in leading and directing the working class and peasantry towards revolution. Ultimately, the Bolsheviks seized power in 1917, leading to the establishment of a communist state.
