Bleeding Kansas refers to the time period where proslavery and anti-slavery supporters fought against each other in a small civil war. This war was a result of the power to control the new territory of Kansas.

With the passage of the Kansas-Nebraska Act in May 1854, the issue of the legality of slavery became a much-heated argument.

The confrontation led to the small but violent war which became known as "Bleeding Kansas".
