The answers are:
- Recognition of universal human rights.
- Pressure from United Nations.
- Growth of nationalism.
- Promises made to colonies during the war.
- European economic weakness.
After the World War II many colonies were granted independence because of the European economic weakness. During the war European colonial countries were sucked dry economically to a point were they were all on the verge of collapsing as countries. After the war they were all in ruins and needed all the funds to rebuild themselves in every aspect. This caused the European colonial countries to grant independence to many of their colonies because they were not able to keep them under control anymore, be it financially or with the military.
