The significance of the Bolshevik Revolution for global communism lies in its establishment of the first communist state. Occurring in 1917, it demonstrated the potential for a socialist overthrow of an existing regime, inspiring leftist movements worldwide. The revolution resulted in the creation of the Soviet Union, which became a model for other communist parties seeking to establish similar regimes. Additionally, it heightened ideological tensions during the Cold War, as capitalist nations responded to the perceived threat of communism with various political and military measures. This revolution fundamentally changed governance and socioeconomic structures in numerous countries.
