World War II reshaped international politics and colonial administrations by accelerating the process of decolonization. The war weakened European powers, leading to a rethinking of colonial rule, especially in Asia and Africa. The emergence of superpowers, namely the United States and the Soviet Union, created a new geopolitical landscape characterized by the Cold War. The establishment of the United Nations aimed to prevent future global conflicts, while the principles of self-determination gained prominence, leading to numerous nations achieving independence. These shifts dramatically altered global power dynamics and social structures in the second half of the 20th century.
