This event, occurring in 1917, inspired revolutionary movements across the globe, challenging established capitalist systems and promoting the idea of socialism. The revolution also led to the Cold War dynamics, where ideologies between capitalist and communist nations became deeply divided, resulting in numerous geopolitical tensions.
