Who were the Border Ruffians from the mid-1800s?

Border Ruffians were pro-slavery activists from Missouri who crossed into Kansas in the mid-1800s to influence the outcome of the territory's decision on slavery. They were involved in violent confrontations with anti-slavery settlers during the period known as "Bleeding Kansas," which was marked by significant conflict over the issue of slavery. Their actions contributed to the tensions that eventually led to the Civil War. The term "Border Ruffians" often carries a negative connotation, reflecting their role in exacerbating violence and unrest in the region.
