The Greensboro sit-in was a pivotal moment in American Civil Rights history. It struck a huge blow to help end segregation and showed that even young people have the power to make great change in the world.

In celebration of the 50th anniversary of this defining moment in history, we invite you to stand up for something YOU believe in.

Send us an essay about a cause you believe in or a wrong in the world that you would fix if you could (ex: saving the environment, ending war, helping hungry children, etc.)

Twenty runner-up entry prize winners will receive a poster and signed copy of Sit-In: How Four Friends Stood Up By Sitting Down.

One grand prize entry winner will receive a trip for 3 to Washington, DC to visit our nation’s capital (subject to rules and restrictions)!*
