Sixty years ago, a group of 13 children sat down in Oklahoma City and changed the course of American history.

It was Aug. 19, 1958, and members of the Oklahoma City NAACP Youth Council walked into an all-white drugstore chain downtown. Sitting at the lunch counter, they politely asked for hamburgers and Cokes.

They were not surprised when their requests were refused, nor when they were asked to leave. They sat in peaceful protest, letting the insults and glares from white customers roll off their backs, patiently waiting to be served.

Two days later, Katz Drug Stores ended its segregation policy.
