What this covers

Colonization joined territorial control to political domination, economic extraction, strategic rivalry and claims of cultural superiority. Its forms varied across settler colonies, direct rule, indirect rule, protectorates and informal influence. Decolonization likewise followed different paths: negotiation, mass politics, armed struggle, international pressure and imperial exhaustion interacted in different proportions. Compare the institutions and economic structures inherited at independence, the drawing of borders, the management of diversity, and the effort to build legitimate states. Keep formal sovereignty distinct from the persistence of unequal economic and geopolitical relationships.
