Final answer:
The goal of the border ruffians during Bleeding Kansas was to illegally vote for pro-slavery measures to ensure Kansas would adopt pro-slavery legislation.
Step-by-step explanation:
During the time of Bleeding Kansas, the goal of the border ruffians, who were pro-slavery Missourians that crossed the border to vote in Kansas, was to vote illegally for pro-slavery measures. The border ruffians were part of the effort to influence the outcome of territorial elections and ensure that Kansas would become a slave state, which included the establishment of a proslavery legislature and the drafting of a proslavery constitution known as the Lecompton Constitution. This turmoil marked a violent and contentious period in Kansas' history as both pro-slavery and antislavery forces sought to sway the political direction of the territory.
