Which policy allowed colonial nations to rule themselves with partial autonomy in the post-WWII era?

The post-World War II era was marked by a significant movement towards decolonization, where former colonies sought independence and self-governance. This process enabled colonial nations to gain varying degrees of autonomy, ultimately leading to complete independence in many cases. Decolonization was driven by various factors, including the weakening of colonial powers after the war, the rise of nationalist movements, and the increasing global support for independence, often articulated through the concept of self-determination.

Self-determination, while a crucial idea related to decolonization, refers specifically to the right of peoples to choose their own political status and governance. It played a pivotal role in the decolonization movements but doesn't directly describe the policy that granted colonial nations autonomy as they transitioned away from colonial rule.

Imperialism represents the practice of extending a nation's power over other territories, while federalism is a political system that divides power between central and regional authorities, which isn’t directly related to the self-governance of former colonies.
