Border ruffians helped to chase abolitionists out of Missouri.

Explanation:

The Border Ruffians were a private army raised by the big slave owners of Missouri, at a time when the history of cotton farming was marked by political conflict over the gaining of new lands in the west, shortly before the Civil War.

They were involved in the bloody events of Bleeding Kansas, at the time of a political race between abolitionists and slavers to determine whether Kansas, created in 1861 as a state, with two representatives in the Senate, would be a slave state or not.  

The Missouri slave owners were actively campaigning for the United States to remain a slave country. They had created the Border Ruffians, which crossed the western shore of Missouri to the neighboring lands of Kansas Territory, where they were engaged in the armed struggle against abolitionists like John Brown.  

By March 1855, the Missouri Border Ruffians invaded Kansas during the first election in the territory and imposed a pro-slavery legislature. In 1857, the governor of the Kansas Territory dismissed them and a fragile peace was established.

Two of their leaders was Douglas County Sheriff Samuel J. Jones from Missouri and Benjamin Franklin Stringfellow, Missouri General Attorney.
