The Iron Curtain divided Europe after World War II, marking the start of the Cold War. This physical and ideological barrier separated communist Eastern Europe from the capitalist West, symbolizing the growing tensions between the Soviet Union and Western powers.
The Cold War emerged as the US and USSR competed for global influence. Their opposing ideologies, nuclear arms race, and formation of rival military alliances like NATO and the Warsaw Pact shaped international politics for decades, leading to proxy wars and crises worldwide.
