How did World War 2 affect democracy throughout the world?

World War II significantly impacted democracy globally by leading to the decline of colonial empires and the rise of nationalist movements, which often sought democratic governance. The war also prompted the establishment of international organizations like the United Nations, promoting human rights and democratic principles. In Europe, the post-war period saw the establishment of democratic governments in many countries, particularly in Western Europe, while in Eastern Europe, the rise of communist regimes challenged democratic ideals. Overall, the war catalyzed a global reevaluation of governance, leading to both the expansion and contraction of democratic practices worldwide.
