1848 Free Soil & Liberty national conventions

National conventions of the Free Soil and Liberty parties met in 1847 and 1848 to nominate candidates for president and vice president in advance of the 1848 United States presidential election. The conventions resulted in the creation of the national Free Soil Party, a union of political abolitionists with antislavery Conscience Whigs and Barnburner Democrats to oppose the westward extension of slavery into the U.S. territories. Former President Martin Van Buren was nominated for president by the Free Soil National Convention that met at Buffalo, New York on August 9, 1848; Charles Francis Adams Sr. was nominated for vice president. Van Buren and Adams received 291,409 popular votes in the national election, almost all from the free states; his popularity among northern Democrats was great enough to deny his Democratic rival, Lewis Cass, the crucial state of New York, throwing the state and the election to Whig Zachary Taylor.
