Answer:
The Border Ruffians
Step-by-step explanation:
The Border Ruffians were the pro-slavery activists who supported slavery. The Border Ruffians were from Missouri (a slave state) who traveled to Kansas territory to vote. They rushed to vote in Kansas from 1854 to 1860 because they wanted the Kansas to be part of the slave state. They often used guns to interfere with the voting election and attacked free-state settlers. Benjamin Stringfellow was one of the notorious Border Ruffians.
