Final answer:
After World War II, major empires such as Japan, France, and Great Britain started giving independence to modern countries as a result of the war's effects on the legitimacy of imperialism, the strain on European imperialists, and the inspiration provided by examples of joint resistance against fascist occupiers.
Step-by-step explanation:
After the major event of World War II, large empires like Japan, France, and Great Britain began giving independence to modern countries. The defeat of Germany and Japan during the war caused people in the nations they had conquered to question the legitimacy of imperialism, and the strain of the war weakened the European imperialists. Furthermore, the war showcased examples of Europeans and Asians fighting side by side against fascist occupiers, inspiring leaders of national liberation movements to advocate for independence. This accelerated the process of decolonization and the granting of independence to former colonies.
