may 25, 1856 - Pottawatomie Massacre

Description:

"The Pottawatomie Massacre occurred on May 25, 1856. It was led by John Brown, an abolitionist who believed in using violence to aid the end of slavery. He and a group of followers murdered five pro-slavery men along the Pottawatomie Creek. This massacre was one of the main events that gave this time period the name “Bleeding Kansas.” It aided the cause of the civil war by infuriating anti-slavery and pro-slavery groups and leading to more violence in the future"(preceden.com).
