Why did African nationalism grow after World War II?

African nationalism experienced significant growth following World War II due to a convergence of economic, political, and social factors that weakened the foundations of colonial rule.

• Wartime Experience: Thousands of Africans served in the military during the war; their return brought "widened horizons" and deep frustration regarding discriminatory treatment and unequal compensation, which fueled nationalist sentiment.1
• Ideological Shifts: The 1941 Atlantic Charter, which proclaimed the right of all peoples to self-determination, served as a powerful catalyst for political activists across the continent.1
• Economic Discontent: Rapid urbanization and economic expansion during the war led to increased worker militancy. When wages failed to keep pace with the rising cost of living, African workers organized into trade unions, creating a new, radicalized constituency for political action.1
• Intellectual Leadership: By the late 1940s, leadership of the Pan-Africanism movement shifted from African Americans to African intellectuals like Kwame Nkrumah, who advocated for political and economic unity to dismantle colonial rule.2
• Imperial Weakness: Post-war Britain faced internal economic struggles and the high costs of maintaining an empire, leading to a shift in policy that eventually accepted the inevitability of decolonization.3
