In 1995, UNESCO published a Declaration of Principles on Tolerance to add to its dialogue about racial equality with recommendations for tolerant treatment of persons with varied racial and cultural backgrounds. It stated "Tolerance is respect, acceptance and appreciation of the rich diversity of our world's cultures, our forms of expression and ways of being human. It is fostered by knowledge, openness, communication, and freedom of thought, conscience and belief. Tolerance is harmony in difference. It is not only a moral duty, it is also a political and legal requirement. Tolerance, the virtue that makes peace possible, contributes to the replacement of the culture of war by a culture of peace." The 1950 UNESCO statement contributed to the 1954 U.S. Supreme Court desegregation decision in Brown v. Board of Education of Topeka.
