The aftermath of World War II led to the establishment of the United Nations in 1945, inspired by the League of Nations and the Atlantic Charter. Major powers including the U.S., USSR, France, Britain, and China shaped global politics, leading to the Nuremberg Trials that prosecuted Nazi leaders. The Iron Curtain divided Europe, while conflicting ideologies fueled the Cold War. Key events included the Marshall Plan, Truman Doctrine, Berlin Airlift, Korean War, and rising tensions exemplified by the Suez Crisis and conflicts in Asia and Latin America, setting the stage for decades of geopolitical struggle.
