Postwar decolonization refers to the process of dismantling colonial empires and granting independence to colonized nations following World War II. This movement was fueled by a combination of factors, including rising nationalism in colonized regions, the weakening of European powers after the war, and the influence of the United States and the Soviet Union, who promoted self-determination. The decolonization wave led to significant political, social, and economic transformations across Asia, Africa, and the Caribbean.
