The Office of the United Nations High Commissioner for Human Rights (OHCHR) is the principal United Nations human rights entity. The General Assembly gives the High Commissioner and her Office a single mandate to promote and protect all human rights. The United Nations Human Rights Programme aims to ensure that the protection and enjoyment of human rights are a reality for all. OHCHR also plays a crucial role in safeguarding the integrity of the three interconnected pillars of the United Nations: peace and security, human rights, and development.
