The United Nations was officially formed in October 1945 to promote cooperation among different countries. It had its roots in the former League of Nations, which was formed after World War I but disbanded after failing to prevent the second World War.
During World War II, a group of 26 nations gathered together to sign the original Declaration of United Nations, in which each individual nation pledged to continue fighting the Axis powers and refuse to negotiate a separate peace with them. Following the war, a conference was held in San Francisco and representatives from 50 different nations attended. At this conference, the United Nations charter was officially ratified.
Peacekeeping is the primary concern of the United Nations. The organization helps negotiate peace treaties and supports the efforts of countries as they move towards democracy. On occasion, the United Nations dispatches soldiers to help with peacekeeping missions. The United Nations also seeks to promote human rights in all countries and strives to prevent the discrimination against and mistreatment of minorities across the globe. Other duties of the United Nations include providing humanitarian aid when necessary, such as organizing the drop-off of food and basic supplies in countries devastated by war and natural disasters.
