Bleeding Kansas,
Bloody Kansas or the
Border War was a series of violent political confrontations in the
United States involving
anti-slavery Free-Staters and pro-slavery "
Border Ruffian" elements in Kansas between 1854 and 1861. The
Kansas–Nebraska Act of 1854 called for
"popular sovereignty"—that is, the decision about slavery was to be made by the settlers (rather than outsiders). It would be decided by votes—or more exactly which side had more votes counted by officials. At the heart of the conflict was the question of whether
Kansas would allow or outlaw slavery, and thus enter the Union as a
slave state or a free state. Pro-slavery forces said every settler had the right to bring his own property, including slaves, into the territory. Anti-slavery "free soil" forces said the rich slaveholders would buy up all the good farmland and work it with black slaves, leaving little or no opportunity for non-slaveholders. As such, Bleeding Kansas was a conflict between anti-slavery forces in the
North and pro-slavery forces from
the South over the issue of
slavery in the United States. The term "Bleeding Kansas" was coined by Republican
Horace Greeley, editor of the
New York Tribune; its violence indicated that compromise was unlikely and thus it presaged the
Civil War.
