The Post-World War II period marked a significant transformation in global politics, economics, and society. Countries like Germany and Japan underwent extensive reconstruction, while new international organizations, such as the United Nations, were established to promote peace and cooperation. This era also saw the emergence of the Cold War, a geopolitical struggle between the United States and the Soviet Union. The division of Europe into Eastern and Western blocs shaped international relations for decades, influencing conflicts and alliances around the world.
