The "Postwar Period" refers to the time following the end of a major conflict, particularly after World War II, which concluded in 1945. This era was marked by significant social, political, and economic changes as countries worked to rebuild and recover from the devastation of war. Many nations focused on establishing peace, promoting international cooperation, and preventing future conflicts through organizations like the United Nations. During the postwar years, there was also a notable shift in global power dynamics, with the emergence of the United States and the Soviet Union as superpowers. This led to the Cold War, a period of political tension and military rivalry that influenced international relations for decades. Additionally, many countries experienced economic growth and social reforms, shaping the modern world.
