The "Post-War Era" refers to the period following the end of a major conflict, particularly after World War II in 1945. This era was marked by significant political, social, and economic changes as countries rebuilt and redefined their identities. Many nations experienced a shift towards democracy, while others faced challenges such as decolonization and the rise of Cold War tensions. In the Post-War Era, there was also a focus on international cooperation, leading to the establishment of organizations like the United Nations. Economically, countries sought to recover through initiatives such as the Marshall Plan, which provided aid to rebuild European economies. This period laid the groundwork for modern global relations and economic systems.
