Establishment of the Committee. In February 1947, in accordance with a decision from the first session of the Commission on Human Rights (E/259), a group consisting of Eleanor Roosevelt, Pen-Chun Chang and Charles Malik, began drafting the International Bill of Human Rights.
The Universal Declaration of Human Rights is a declaration (something said in an important way) by the United Nations General Assembly. It talks about basic human rights -- rights that all people have just because they are human. It was adopted (agreed to) by the United Nations General Assembly on December 10, 1948.
