How Russia's government changed after world war 1?

After World War I, Russia underwent a radical transformation with the collapse of the Tsarist autocracy and the rise of the Bolshevik Party, led by Vladimir Lenin. The February Revolution of 1917 resulted in the abdication of Tsar Nicholas II and the establishment of a provisional government, which was later overthrown by the Bolsheviks in the October Revolution. This led to the establishment of a communist government, marked by the withdrawal from World War I and the beginning of a civil war, ultimately culminating in the formation of the Soviet Union in 1922. The new government implemented significant social and economic reforms, including nationalization of industry and land redistribution.
