Final answer:
The mid-1850s Kansas elections resulted in both proslavery and antislavery groups claiming victory amid widespread fraudulent voting and acts of violence, contributing to the turmoil known as Bleeding Kansas.
Step-by-step explanation:
As a result of the elections to choose a government in Kansas in the mid-1850s, both proslavery and antislavery groups claimed victory, and the process was marred by fraud and violence. Proslavery advocates led by David Atchison, a Missouri senator, cast votes in the Kansas elections to secure a proslavery majority in the territorial legislature, despite thousands of illegal ballots being cast. Antislavery Free Soilers won the new elections ordered by Governor Andrew Reeder, but those elected were not seated by the proslavery legislature, which passed laws to undermine the Free Soil influence, escalating the conflict known as Bleeding Kansas.
