The main social and political impact of the Bolshevik Revolution, which occurred in October 1917, was the establishment of a communist government in Russia. The overthrow of the Provisional Government by the Bolsheviks, led by Vladimir Lenin, marked a significant shift from monarchy to a socialist state. This revolution aimed to address issues such as poverty, inequality, and worker rights, significantly influencing global politics. The rise of the Soviet Union provided a model for other revolutionary movements worldwide and initiated a prolonged period of ideological conflict during the Cold War, reshaping international relations and domestic policies in many countries.
