The Universal Declaration of Human Rights was adopted by the United Nations on December 10, 1948. Eleanor Roosevelt chaired the commission that established the Declaration. The impetus for the Declaration was the previous half century of horrific violence of the two world wars, and especially the events of the Holocaust. Broadly speaking, the content of the Declaration was inspired by Franklin Delano Roosevelt's 1941 State of the Union address, known as the Four Freedoms speech. The UDHR became the template for other United Nations commissions and remains the guide for achieving an international understanding of the rights of all human individuals.
