Throughout the world, the UN and its agencies assist refugees, set up programmes to clear landmines, help expand food production, lead the fight against AIDS and much more.
The United Nations was formed on 24 October 1945 by 51 countries. Today, 191 countries - nearly every nation in the world - belong to the UN. At the Millenium Summit in 2000 the UN’s member countries agreed on eight Millenium Development Goals to tackle poverty worldwide.
Each member country has to sign the UN Charter. It sets out basic principles of international relations and all members of the UN must accept these principles.
According to the Charter, the UN has four purposes:
- to maintain international peace and security
- to develop friendly relations among nations
- to cooperate in solving international problems and in promoting respect for human rights
- to be a centre for harmonizing the actions of nations
