Kansas–Nebraska Act - Bleeding Kansas

Bleeding Kansas

Pro-slavery settlers came to Kansas mainly from neighboring Missouri. Their influence in territorial elections was often bolstered by resident Missourians who crossed into Kansas solely for the purpose of voting in such ballots. They formed groups such as the Blue Lodges and were dubbed border ruffians, a term coined by opponent and abolitionist Horace Greeley. Abolitionist settlers, known as "Jayhawkers" moved from the East with express purpose of making Kansas a free state. A clash between the opposing sides was inevitable.

Successive territorial governors, usually sympathetic to slavery, attempted unsuccessfully to maintain the peace. The territorial capital of Lecompton, Kansas, the target of much agitation, became such a hostile environment for Free-Staters that they set up their own unofficial legislature at Topeka.

John Brown and his sons gained notoriety in the fight against slavery by murdering five pro-slavery farmers in the Pottawatomie Massacre with a broadsword. Brown also helped defend a few dozen Free-State supporters from several hundred angry pro-slavery supporters at the town of Osawatomie.

Hostilities between the factions reached a state of low-intensity civil war, which was damaging to President Pierce. The nascent Republican Party sought to capitalize on the scandal of "Bleeding Kansas". Routine ballot-rigging and intimidation practiced by both pro- and anti-slavery settlers failed to deter the immigration of anti-slavery settlers, who won a demographic victory in the race to populate the state.
