Why did people push for decolonization after World War 2?

After World War II, many people pushed for decolonization due to a combination of factors, including the weakening of European powers and the rise of nationalist movements in colonized regions. The war had exposed the contradictions of colonialism, particularly in light of the principles of self-determination and human rights promoted by the Allies. Additionally, the emergence of the United States and the Soviet Union as superpowers fueled anti-colonial sentiments, as both sought to expand their influence by supporting decolonization efforts. This culminated in a global wave of independence movements throughout the mid-20th century.
