The 1855 Kansas Territory elections were a series of pivotal moments in the "Bleeding Kansas" conflict between pro-slavery individuals and "Free-Staters" in Kansas Territory. The initial elections for territorial legislature, held on March 30, 1855, were marred by widespread voter fraud, intimidation, and violence, as pro-slavery forces from neighboring Missouri crossed the border to cast ballots and suppress anti-slavery voters. In response, Kansas Territorial governor, Andrew H. Reeder, ordered new elections to be held on May 22 in certain districts. But even after the corrective elections, pro-slavery candidates still managed to win a majority of seats in the territorial legislature. When the legislature convened in July, it promptly ejected all the Free-State candidates who had won seats in the May elections. This act led to many Kansans lambasting the body as the "Bogus Legislature."
In October 1855, elections were held for a Congressional delegate to represent Kansas Territory in the House of Representatives. Pro-slavers held their elections on October 1 and choose John Wilkins Whitfield, whereas Free-Staters held theirs on October 8 and selected Reeder. Whitfield was initially seated as the lawful delegate, but after Reeder petitioned the House, the seat was vacated on August 1, 1856 and a new election was ordered.
