Bleedimg Kansas was a violent civil confrontation during the years 1854 and 1861, caused by ideological and political differencies related to the legality of slavery. During 1854, the Congress passed the Kansas-Nebraska Act which divided the Great Plains into two states, and the legality of slavery would be decided by the settlers in these two states; this was called popular sovereignty. Proslavery and abolitionists tried to influence the decision and violence erupted when the anti-slavery town, Lawrence, in Kansas was raided by border ruffians.This is the event that causes the Bleeding Kansas.
Hope this helps.
