The United Nations (UN) was created at the end of World War II as an international peacekeeping organization and a forum for resolving conflicts between nations.
The UN replaced the ineffective League of Nations, which had failed to prevent the outbreak of the Second World War.
The UN was established on October 24, 1945, with headquarters in Manhattan, New York City, and reflected the rise of the United States to global leadership in the postwar period.
Only the United States and Japan came out of the war in better financial shape than before. Uneven distribution of wealth, overproduction by business and agriculture, and the fact that many Americans were buying less.
