Why did nationalist movements gain strength in Asia and Africa after world war II?

Asian and African nations wanted a return to colonial style governments
People in the colonies wanted to choose their own government
The colonies were no longer good for resources
Colonizers no longer wanted to live in the colonies

Nationalist movements gained strength in Asia and Africa after World War II mainly because people in the colonies wanted to choose their own government. The experience of participating in the war effort and the subsequent dismantling of European empires during the war created a sense of empowerment among colonized peoples, who began to demand independence and self-determination. Additionally, the ideas of self-rule and democracy spread globally, inspiring nationalist movements in Asia and Africa to fight for independence from colonial powers. The weakening of colonial economies and the changing attitudes of colonizers towards maintaining control over distant territories also contributed to the rise of nationalist movements in these regions.
