11.5 Cold War

The Cold War emerged as a defining conflict of the Modern Period, shaping global politics for nearly half a century. Tensions between the United States and Soviet Union escalated rapidly following their alliance during World War II, leading to a bipolar world order.

This period saw the formation of key alliances like NATO and the Warsaw Pact, as well as major events such as the Cuban Missile Crisis and the Space Race. The conflict's legacy continues to influence geopolitics today.
