It is a testament to the greatness of Martin Luther King Jr. that nearly every major city in the U.S. has a street or school named after him. It is a measure of how sorely his achievements are misunderstood that most of them are located in black neighborhoods. Even after the Supreme Court struck down segregation in 1954, what the world now calls human-rights offenses were both law and custom in much of America. Before King and his movement, a tired and thoroughly respectable Negro seamstress like Rosa Parks could be thrown into jail and fined simply because she refused to give up her seat on an Alabama bus so a white man could sit down. A six-year-old black girl like Ruby Bridges could be hectored and spit on by a white New Orleans mob simply because she wanted to go to the same school as white children. A 14-year-old black boy like Emmett Till could be hunted down and murdered by a Mississippi gang simply because he had supposedly made suggestive remarks to a white woman.
The movement that King led swept all that away.
