The Republican Party was founded in Ripon, Wisconsin in 1854, with the help of Francis Preston Blair. The Republican Party was formed by people who did not like the Kansas-Nebraska Act of 1854, which would let each territory allow slavery. The Republican Party was founded by past members of the Free Soil Party and the Whig Party who wanted to stop the expansion of slavery. The founders of the Republican Party wanted to stop the expansion of slavery because they believed it was against the ideals of the Constitution and Declaration of Independence. Some founders of the Republican Party wanted to abolish slavery everywhere in the United States. The Republican Party's first candidate for President of the United States was John C. Frémont in 1856.
