The global organization established to promote international cooperation after World War II is the United Nations (UN). Formed on October 24, 1945, the UN aimed to foster peace and prevent future conflicts through diplomacy and collective action. It replaced the ineffective League of Nations and has since taken on various humanitarian, economic, and social issues worldwide. The UN consists of several specialized agencies, including the World Health Organization (WHO) and the International Monetary Fund (IMF). Its establishment was a response to the devastation of the war, and it plays a crucial role in addressing global challenges such as poverty, human rights, and environmental sustainability.
