Bleeding Kansas

Bleeding Kansas, Bloody Kansas, or the Border War, was a series of violent civil confrontations in the Kansas Territory, and to a lesser extent in western Missouri, between 1854 and 1859. It emerged from a political and ideological debate over the legality of slavery in the proposed state of Kansas.

The conflict was characterized by years of electoral fraud, raids, assaults, and murders carried out in the Kansas Territory and neighboring Missouri by proslavery "border ruffians" and retaliatory raids carried out by antislavery "free-staters". According to Kansapedia of the Kansas Historical Society, 56 political killings were documented during the period, and the total may be as high as 200. It has been called a "tragic prelude", or an overture, to the American Civil War, which immediately followed it.

The conflict centered on the question of whether Kansas, upon gaining statehood, would join the Union as a slave state or a free state. The question was of national importance because Kansas's two new senators would affect the balance of power in the U.S. Senate, which was bitterly divided over the issue of slavery. The Kansas–Nebraska Act of 1854 called for popular sovereignty: the decision about slavery would be made by popular vote of the territory's settlers rather than by legislators in Washington, D.C. Existing sectional tensions surrounding slavery quickly found focus in Kansas.

Missouri, a slave state since 1821, was populated by many settlers with Southern sympathies and pro-slavery views, some of whom tried to influence the Kansas decision by entering Kansas and claiming to be residents. The conflict was fought politically, and between civilians, where it eventually degenerated into brutal gang violence and paramilitary guerrilla warfare.

Kansas had a state-level civil war that would soon be replicated on a national basis. It had two different capitals (proslavery Lecompton and antislavery Lawrence, then Topeka), two different constitutions (the proslavery Lecompton Constitution and the antislavery Topeka Constitution), and two different legislatures (the so-called "bogus legislature" in Lecompton and the antislavery body in Lawrence). Both sides sought and received help from outside, with the proslavery side receiving aid from the federal government, as Presidents Franklin Pierce and James Buchanan openly supported the proslavery partisans. Both claimed to reflect the will of the people of Kansas. The proslavers used violence and threats of violence, and the free-staters responded in kind. After much commotion, including a congressional investigation, it became clear that a majority of Kansans wanted Kansas to be a free state, but this required congressional approval, which Southerners in Congress blocked.

Kansas was admitted to the Union as a free state the same day that enough Southern senators had departed, during the secession crisis that led to the Civil War, to allow it to pass (effective January 29, 1861). Partisan violence continued along the Kansas–Missouri border for most of the war, although Union control of Kansas was never seriously threatened. Bleeding Kansas demonstrated that armed conflict over slavery was unavoidable. Its severity made national headlines, which suggested to the American people that the sectional disputes were unlikely to be resolved without bloodshed, and it, therefore, acted as a preface to the American Civil War. The episode is commemorated with numerous memorials and historic sites.

As abolitionism became increasingly popular in the United States and tensions between its supporters and detractors grew, the U.S. Congress maintained a tenuous balance of political power between Northern and Southern representatives. At the same time, the increasing emigration of Americans to the country's western frontier and the desire to build a transcontinental railroad that would connect the eastern states with California urged incorporation of the western territories into the Union. The inevitable question was how these territories would treat the issue of slavery when eventually promoted to statehood. This question had already plagued Congress during political debates following the Mexican–American War. The Compromise of 1850 had at least temporarily solved the problem by permitting residents of the Utah and New Mexico Territories to decide their own laws with respect to slavery by popular vote, an act which set a new precedent in the ongoing debate over slavery.

In May 1854, the Kansas–Nebraska Act created from Indian lands the new territories of Kansas and Nebraska for settlement by U.S. citizens. The act was proposed by Senator Stephen A. Douglas of Illinois as a way to appease Southern representatives in Congress, who had resisted earlier proposals to admit states from the Nebraska Territory because of the Missouri Compromise of 1820, which had explicitly forbidden the practice of slavery in all U.S. territory north of 36°30' latitude and west of the Mississippi River, except in the state of Missouri. Southerners feared the incorporation of Nebraska would upset the balance between slave and free states and thereby give abolitionist Northerners an advantage in Congress.
