After World War II, several key agreements were established to reshape the global order and promote peace. The most significant of these was the United Nations, formed in 1945 to foster international cooperation and prevent future conflicts. Additionally, the Bretton Woods Conference led to the creation of the International Monetary Fund and the World Bank, aimed at stabilizing economies and facilitating reconstruction. Another important agreement was the Marshall Plan, initiated in 1948, which provided financial aid to help rebuild European economies. The NATO alliance was also formed in 1949 to ensure collective security among Western nations against potential threats, particularly from the Soviet Union.
