C) The competition of opposing groups, as the whole fight was about pro slavery , there were abolitionists, and of course those who wanted slavery!
What contributed to the events of "Bleeding Kansas" was the competition of opposing political groups, regarding the issue of slavery.
It encompasses a series of violent political and popular confrontations between 1854 and 1861, in the Kansas Territory and the western border towns of Missouri, between anti-slavery "Free Staters" and "Border Ruffians", supporters of slavery.
The events of Bleeding Kansas led directly to the American Civil War and conditioned relations between Kansas and Missouri.
