The horrors of the war made the world leaders realise the need for an international organisation for peace. World leaders such as British Prime Minister Winston Churchill, Soviet Leader Stalin and US President Roosevelt met at various conferences to decide about the formation of this organisation.
Finally, on 24 October 1945 at a conference in San Francisco, the United Nations Charter was adopted by the members of 50 nations and the United Nations Organisation (UNO) was formed. Since then 24 October is celebrated every year as UN Day, all over the world.
The UNO is based on the principle of sovereignty and equality of all nations. The main aims of the UNO are to maintain peace and security in the world, to prevent future war, to solve international disputes peacefully and to promote international cooperation.
Objectives of United Nations Organisation
Like the League of Nation, which was established after World War I, the UN too had a major objective of maintaining international peace and security. It also had another major objective to develop friendly relations among nations on the basis of equality and achieve international cooperation in solving economic, social, cultural and humanitarian problems.
To promote human rights and fundamental freedom for the people of the world was one of the aims of the UN. It was also to act as a common platform for harmonising the activities of various nations for the attainment of the objectives of the UN.
