Postcolonialism is the critical academic study of the cultural, political and economic legacy of colonialism and imperialism, focusing on the impact of human control and exploitation of colonized people and their lands. The field started to emerge in the 1960s, as scholars from previously colonized countries began publishing on the lingering effects of colonialism, developing a critical theory analysis of the history, culture, literature, and discourse of imperial power.

Decolonization is the undoing of colonialism, the latter being the process whereby imperial nations establish and dominate foreign territories, often overseas. The meanings and applications of the term are disputed. Some scholars of decolonization focus especially on independence movements in the colonies and the collapse of global colonial empires. Other scholars extend the meaning to include economic, cultural and psychological aspects of the colonial experience.
