Hey!

Free-Soil Party, (1848–54), minor but influential political party in the pre-Civil War period of American history that opposed the extension of slavery into the western territories. Fearful of expanding slave power within the national government, Rep. David Wilmot of Pennsylvania in 1846 introduced into Congress his famous Wilmot Proviso, calling for the prohibition of slavery in the vast southwestern lands that had been newly acquired from Mexico. The Wilmot concept, which failed in Congress, was a direct ideological antecedent to the Free-Soil Party. Disappointed by the ambivalent position of the Whig Party toward slavery, “Conscience” Whigs held a convention in August 1848 at Buffalo, New York. There they were joined by delegates from 17 states drawn from the Liberty Party and the antislavery faction of the New York Democrats, known as “Barnburners.” The Free-Soilers’ historic slogan calling for “free soil, free speech, free labour, and free men” attracted small farmers, debtors, village merchants, and household and mill workers, who resented the prospect of black-labour competition—whether slave or free—in the territories.

In early 1840, abolitionists founded the Liberty Party as a political outlet for their antislavery beliefs. A mere eight years later, bolstered by the increasing slavery debate and growing sectional conflict, the party had grown to challenge the two mainstream political factions in many areas. In The Liberty Party, 1840–1848, Reinhard O. Johnson provides the first comprehensive history of this short-lived but important third party, detailing how it helped to bring the antislavery movement to the forefront of American politics and became the central institutional vehicle in the fight against slavery.

As the major instrument of antislavery sentiment, the Liberty organization was more than a political party and included not only eligible voters but also disfranchised African Americans and women. Most party members held evangelical beliefs, and as Johnson relates, an intense religiosity permeated most of the group’s activities. He discusses the party’s founding and its national growth through the presidential election of 1844; its struggles to define itself amid serious internal disagreements over philosophy, strategy, and tactics in the ensuing years; and the reasons behind its decline and merger into the Free Soil coalition in 1848.
