Final answer:
The fraudulent proslavery vote in the territorial elections of May 21, 1856, in Kansas resulted in proslavery active violence in Lawrence.
Step-by-step explanation:
The fraudulent proslavery vote in the territorial elections of May 21, 1856, in Kansas led to a wave of proslavery active violence. In an effort to arrest the leaders of the antislavery government for treason, hundreds of proslavery forces, mostly from Missouri, marched into Lawrence. They burned a local hotel, looted houses, destroyed antislavery printing presses, and killed one person. This violent incident was part of the larger conflict known as Bleeding Kansas, where proslavery and antislavery advocates fought for control over the territory.
