Answer:After World War II, the world experienced major social, economic, and political changes. Socially, there was a push for civil rights, decolonization, and greater equality, especially in the U.S. and former colonies. Economically, many countries experienced rapid growth and reconstruction through efforts like the Marshall Plan, while the U.S. emerged as a global economic leader. Politically, the world became divided between two superpowers—the United States and the Soviet Union—leading to the Cold War. Many new nations gained independence, and global organizations like the United Nations gained importance in promoting peace and cooperation.
