From the entry, Colonialism:
"Colonialism as a broad concept that refers to the project of European political domination from the sixteenth to the twentieth centuries that ended with the national liberation movements of the 1960s. Post-colonialism will be used to describe the political and theoretical struggles of societies that experienced the transition from political dependence to sovereignty.
In the humanities, postcolonial theory tends to reflect the influence of poststructuralist thought, while theorists of decolonization focus on social history, economics, and political institutions. Whereas postcolonial theory is associated with the issues of hybridity, diaspora, representation, narrative, and knowledge/power, theories of decolonization are concerned with revolution, economic inequality, violence, and political identity."
