Founded at the end of the Second World War, the United Nations is an international organization made up of 193 Member States committed to maintaining international peace and security.Every day the UN works to tackle global challenges and deliver results for those most in need.Giving life-saving support to populations hit by humanitarian crises, helping build and keep the peace in conflict-ridden areas, supporting governments and their citizens to advance development and fight poverty, and promoting human rights worldwide are the core pillars of the work of the United Nations and the mandates it receives from its Member States.The Charter of the United Nations is available in full at: http://www.un.org/en/documents/charter/
