The world powers created the United Nations (UN) after World War II in 1945. The UN is an international organization that was established to promote peace, security, and cooperation among countries around the world. One of its main objectives is to prevent the outbreak of wars and to resolve conflicts peacefully. The UN is also involved in a range of activities, such as promoting human rights, advancing social and economic development, providing humanitarian aid, and protecting the environment. The UN also created various bodies and specialized agencies such as the International Court of Justice, the World Health Organization (WHO), and the United Nations Educational, Scientific and Cultural Organization (UNESCO), among others, to carry out its objectives.
