Why did African and Asian countries overthrow colonial rule?

African and Asian countries overthrew colonial rule primarily due to a desire for self-determination and independence, fueled by rising nationalism and the influence of global movements advocating for decolonization. Economic exploitation, cultural oppression, and social injustices under colonial regimes further galvanized resistance among local populations. Additionally, the weakening of colonial powers after World War II, alongside growing international support for independence movements, provided opportunities for these nations to challenge and ultimately dismantle colonial rule.
