What is the colonial revolution? What is the post-colonial world?

Lenin pointed out that the colonial revolution is to encourage the weak ethnic groups in the colonial society to resist the national oppression from imperialism and the class oppression of the domestic bourgeoisie. This is the so-called dual revolution of class and nation.

Post-colonial world refers to the group formed by capitalist countries in Europe and America during the cold war and post-cold war after World War II.
