On February 28, 1854, the Republican party was envisioned in a Ripon, Wisconsin, school house (which still stands today), by 30 men who felt a new party must be formed with the intention of halting the spread of slavery throughout the United States and its territories. There is still some debate about the official beginning of the party, as the first meeting of a group officially calling themselves Republicans did not occur until July 1854 in Jackson, Michigan, but the Ripon meeting laid an important foundation for the party’s development.
The group met primarily in opposition to the Kansas-Nebraska Act, an 1854 bill passed under the leadership of future Democratic presidential candidate Stephen A. Douglas. The new law nullified the Missouri Compromise of 1820, which would have forbidden slavery in Kansas or Nebraska, and instead instituted popular sovereignty, which allowed for residents to vote on whether to bring the territories into the Union as “slave states” or “free states.” The most famous Republican of his time, Abraham Lincoln engaged Douglas in seven well-known debates in 1858, discussing issues such as the Kansas-Nebraska Act and the Dred Scott case. These debates helped bring Lincoln to national prominence, and in 1860 he became the first Republican to successfully run for president (John C. Fremont ran unsuccessfully in 1856.).
Opening History provides many resources related to the history of the Republican Party, the Kansas-Nebraska Act, and Abraham Lincoln. Territorial Kansas Online, a project of the Kansas State Historical Society and University of Kansas, sheds light on the politics and violence that stemmed from the Kansas-Nebraska Act, and the Abraham Lincoln Historical Digitization Project from Northern Illinois University offers a focus on Lincoln’s Illinois years. The Iowa Women’s Archives Founders collection from the University of Iowa offers a later view of the Republican Party, including materials on Louise Noun, the first female chair of the Republican National Committee.
