The United Nations is the largest and most consequential inter-governmental organization.  It was established by the UN Charter in 1945 and replaced the earlier League of Nations.  It currently has 193 member states.  In addition to its primary mandate of maintaining international peace and security, the UN also promotes economic and social development, protects human rights, provides humanitarian aid and disaster relief, and facilitates the development of international law.
