The lunch counters in the FW Woolworth dime stores are right up there with Rosa Parks and the bus boycotts when it comes to the history of the Civil Rights movement during the 1950s.
In the South, of course, blacks were not served at these eateries, and that's when the famous sit-in demonstrations began. College students from all over the south organized and started showing up at these Dime stores, taking up spaces on the stools at the counters, requesting to be served.
In the process of being refused, they were attacked, spat upon and dragged out by police but new teams would show up everyday. This went on for a whole summer as the movement gained national attention. It took a few more years before these Jim Crow laws were finally abolished.
