"Bloody Kansas" was a series of violent civil confrontations in the United States between 1854 and 1861 which emerged from a political and slavery based conflicts. The Pro-slavers would try to settle in the new land to try and bring it under the influence of slavery. While on the other hand the Free-soldiers would try to make it slavery abolished in the land. A cause of this would be conflict and feud. Where they'd fight over whether it was under slavery or not. An effect of the event would be people of the opposite side getting mad of whether it would be free or slaves would cause a lot of fighting even death.
