The main impact of the **Russian Revolution** on the global political landscape was the emergence of communism as a significant ideological force. This shift led to the establishment of the Soviet Union, which promoted revolutionary movements worldwide. The revolution inspired leftist groups across Europe and the Americas, challenging existing capitalist frameworks. Additionally, it intensified Cold War tensions between the capitalist West, led by the United States, and the communist East, creating a geopolitical divide that shaped international relations for decades. The revolution also influenced anti-colonial movements in Asia and Africa.
