About the United Nations
The United Nations (UN) is an international organization founded in 1945. It is currently made up of 193 Member States. The mission and work of the United Nations are guided by the purposes and principles contained in its founding Charter.
Due to the powers vested in the UN Charter and its unique international character, the United Nations can take action on the issues confronting humanity in the 21st century, such as peace and security, climate change, sustainable development, human rights, disarmament, terrorism, humanitarian and health emergencies, gender equality, governance, food production, and more.
The UN also provides a forum for its members to express their views in the General Assembly, the Security Council, the Economic and Social Council, and other bodies and committees. By enabling dialogue between its members, and by hosting negotiations, the Organization has become a mechanism for governments to find areas of agreement and solve problems together.
The UN's Chief Administrative Officer is the Secretary-General.
The UN Charter
The Charter of the United Nations was signed on 26 June 1945, in San Francisco, at the conclusion of the United Nations Conference on International Organization, and came into force on 24 October 1945. The Statute of the International Court of Justice is an integral part of the Charter. The full document is available here.
The Secretary General
Equal parts diplomat and advocate, civil servant and CEO, the Secretary-General is a symbol of United Nations ideals and a spokesman for the interests of the world's peoples, in particular the poor and vulnerable among them. The current Secretary-General, and the eighth occupant of the post, is Mr. Ban Ki-moon of the Republic of Korea, who took office on 1 January 2007.
The Charter describes the Secretary-General as "chief administrative officer" of the Organization, who shall act in that capacity and perform "such other functions as are entrusted" to him or her by the Security Council, General Assembly, Economic and Social Council and other United Nations organs. The Charter also empowers the Secretary-General to "bring to the attention of the Security Council any matter which in his opinion may threaten the maintenance of international peace and security". These guidelines both define the powers of the office and grant it considerable scope for action. The Secretary-General would fail if he did not take careful account of the concerns of Member States, but he must also uphold the values and moral authority of the United Nations, and speak and act for peace, even at the risk, from time to time, of challenging or disagreeing with those same Member States.
