The impact of the Bolshevik Revolution on global politics was profound, as it marked the first successful overthrow of a capitalist system in favor of a communist regime. This inspired leftist movements around the world and heightened fears of communism, leading to the Cold War between the United States and the Soviet Union. The revolution facilitated the promotion of socialist ideologies and policies globally, leading to the formation of communist parties in various nations. The establishment of a communist superpower also shifted geopolitical dynamics, resulting in diverse political struggles and alignments throughout the 20th century.
