The U.N.O. is the world organization that replaced the League of Nations. It provides a forum for states to come together and discuss matters of mutual interest particularly of peace and war. The primary task of the U.N.O. is to maintain and promote world peace and punish the aggressor and promote economic, social and cultural co­operation among states.

It provides machinery for the pacific settlement of international disputes. It performs its tasks through various agencies and organs like the General Assembly, the Security Council, the Eco­nomic and Social Council, the UNESCO and W.H.O. etc.


The U.N.O. was conceived as early as 1914, when the Atlantic Charter was drawn up on the principle of equality of states and their freedom to choose any form of government they liked. Representa­tives of 26 governments in 1942 signed the United Nations Declaration on the basis of Adantic Charter.

The United Nations charter was drawn up by the representatives of 50 countries at San Francisco in June, 1945 on the basis of proposals worked out by representatives of the U.K., the U.S.A., theU.S.S.R. and China at Dumbarton Oaks in 1944.
