Question

*
Know-nothings
Whigs
Free-Soilers
Republicans

Answer 1

The party you are referring to is the Republicans. The Republican Party, which emerged in the 1850s, was known for its opposition to the expansion of slavery into the territories, and it gained support from various groups, including abolitionists. John Brown, a radical abolitionist, is often associated with the Republican Party's broader anti-slavery stance, even though he himself had a tumultuous relationship with the party's mainstream leaders. The other parties mentioned—Know-Nothings, Whigs, and Free-Soilers—had different focuses and were not exclusively abolitionist in nature.
