UN headquarters in the context of "Wallace Harrison"

The Charter of the United Nations, also referred to as the UN Charter, is the foundational treaty of the United Nations. It establishes the purposes, governing structure, and overall framework of the United Nations System, including its principal organs: the Secretariat, General Assembly, Security Council, Economic and Social Council, International Court of Justice, and Trusteeship Council. The UN Charter is an important part of public international law, and is the foundation for much of international law governing the use of force, pacific settlement of disputes, arms control, and other important functions of the maintenance of international peace and security.

The UN Charter mandates the United Nations and its member states to maintain international peace and security, uphold international law, achieve "higher standards of living" for their citizens, address "economic, social, health, and related problems", and promote "universal respect for, and observance of, human rights and fundamental freedoms for all without distinction as to race, sex, language, or religion". As a charter and constituent treaty, its rules and obligations are binding on all members and supersede those of other treaties.

The United Nations Department of Political and Peacebuilding Affairs (DPPA) is a department of the Secretariat of the United Nations (UN) with responsibility for monitoring and assessing global political developments and advising and assisting the UN secretary-general and his envoys in the peaceful prevention and resolution of conflict around the world. The department manages field-based political missions in Africa, Central Asia, and the Middle East, and has been increasing its professional capacities in conflict mediation and preventive diplomacy. DPPA also oversees UN electoral assistance to Member States of the organization. Established in 1992, the department's responsibilities also include providing secretariat support to the UN Security Council and two standing committees created by the General Assembly concerning the Rights of the Palestinian People and Decolonization. DPPA is based at the UN headquarters in New York City.
