paragraph_text: Bleeding Kansas, Bloody Kansas or the Border War was a series of violent political confrontations in the United States between 1854 and 1861 involving anti-slavery ``Free - Staters ''and pro-slavery`` Border Ruffian'', or ``southern ''elements in Kansas. 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. 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. 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, and its violence indicated that compromise was unlikely, and thus it presaged the Civil War.
