Why did European powers face growing pressure to decolonize after World War II?

Following World War II, European powers faced mounting pressure to decolonize due to a convergence of geopolitical, economic, and social factors:

• Superpower Influence: The United States and the Soviet Union emerged as dominant global powers and generally opposed traditional colonialism, preferring to exert influence through indirect ideological, economic, and military means.1
• International Pressure: Organizations like the United Nations became central forums for anticolonial sentiment. In 1960, the General Assembly passed a landmark resolution demanding immediate independence for colonial territories, further legitimizing the global movement for self-determination.23
• Rising Nationalism and Conflict: Revolutionary movements within the colonies grew increasingly militant, making the maintenance of overseas territories prohibitively expensive and violent for European nations.12
• Domestic Exhaustion: War-weary European publics became increasingly unwilling to bear the financial and political costs of imperialism, leading governments to prioritize domestic social expenditures over maintaining distant empires.14

Ultimately, these pressures convinced colonial powers that the era of formal empire was unsustainable, leading to a rapid transition toward independence across Africa and Asia.14
