The main objective of the Russian Revolution of 1917 was to overthrow the existing autocratic regime of Tsar Nicholas II and establish a socialist government. The revolution aimed to address widespread dissatisfaction with poverty, food shortages, and the government's handling of World War I. It consisted of two main phases: the February Revolution, which led to the abdication of the tsar, and the October Revolution, which saw the Bolsheviks, led by Vladimir Lenin, seize power. The ultimate goal was to end the imperial rule, redistribute land to the peasantry, and implement a government based on Marxist principles, deeply-transforming Russian society.
