Question

Border Ruffians definition

Answer 1

Border Ruffians: pro‑slavery activists, mostly from Missouri, who in the mid‑1850s crossed into the Kansas Territory to illegally influence whether Kansas would enter the Union as a slave state. They used intimidation, threats, ballot‑stuffing, and occasional violence (notably during the 1855 territorial elections and events such as the Sack of Lawrence) and were a major factor in the violent conflict known as "Bleeding Kansas." They were not a formal military unit but acted in loosely organized groups, sometimes with encouragement from pro‑slavery politicians; their efforts ultimately failed when Kansas was admitted as a free state in 1861.
