The United Nations Commission on Human Rights (UNCHR) was a functional commission within the overall framework of the United Nations from 1946 until it was replaced by the United Nations Human Rights Council in 2006. It was a subsidiary body of the UN Economic and Social Council (ECOSOC), and was also assisted in its work by the Office of the United Nations High Commissioner for Human Rights (UNOHCHR). It was the UN's principal mechanism and international forum concerned with the promotion and protection of human rights.
