What this topic is asking
Topic 9.9 asks you to explain decolonization: the rapid dismantling of the European overseas empires after World War II, its causes, anti-colonial nationalism, European weakness, and Cold War ideals, and its consequences for Europe and the world. The College Board wants you to see the undoing of the empires built in Unit 7.
The causes of decolonization
How the war accelerated it
The process and its variety
Decolonization did not follow a single path.
The consequences
Why it mattered
Decolonization is the undoing of the imperial expansion of Unit 7 and a defining process of the contemporary era. It reflects the eclipse of the European powers by the superpowers (Topic 9.4) and the triumph of the anti-colonial nationalism that imperialism itself had provoked (Topic 7.7). Its consequences, new nations, migration, and lasting global ties, reshaped both the wider world and Europe itself, contributing to the diverse, interconnected, globalized continent of the present (Topic 9.13). It is a powerful example of how the forces Europe unleashed abroad returned to transform Europe at home.
