Why did many African colonies gain independence during the 1960s?

The wave of independence that swept across Africa during the 1960s was driven by a combination of internal shifts within the colonies and the changing circumstances of European powers following World War II.12

Key factors contributing to this rapid decolonization include:

• Rise of Nationalism: Growing nationalistic sentiment among African populations, which had been building since before the war, intensified as people demanded self-determination and an end to foreign rule.12
• European Economic and Political Constraints: After the war, European powers—particularly Britain and France—faced significant financial strain and lacked the domestic political support necessary to maintain their overseas empires. The exorbitant costs of imperialism made continued colonial administration increasingly unsustainable.31
• Changing Global Attitudes: A shift in international opinion, facilitated by the United Nations, placed pressure on colonial powers to grant independence. In 1960, the UN General Assembly adopted a landmark resolution calling for the immediate transfer of power to colonial peoples.4
• The "Demonstration Effect": The successful independence of early leaders, such as Kwame Nkrumah in Ghana (1957), served as a catalyst, making it difficult for colonial powers to deny similar demands from neighboring territories.35
