"On the morning of September 23, 1957 nine African-American teenagers stood up to an angry crowd protesting integration in front of Little Rock's Central High as they entered the school for the first time. This event, broadcast around the world, made Little Rock the site of the first important test of the U.S. Supreme Court’s historic Brown v. Board of Education of Topeka decision."
