may 21, 1856 - Bleeding Kansas
Description:
Basically a mini-Civil War in the U.S. Due to the establishment of popular sovereignty in the territories of Kansas and Nebraska, the territory was flooded with Northern and Southern settlers wanting to make the state in their side. Eventually, tensions between the settlers would be extremely fierce that there would be murders on both sides to reduce their opponent's population in order to win popular sovereignty vote.
One of the most famous and most radical settlers would be John Brown. He and his sons would murder a lot of slaveholders in Kansas. He was soon arrested by Colonel Robert E. Lee.
