What other third parties emerged in Antebellum era? and how did the liberty party differ from them?

Answer:Liberty Party, U. S. political party (1840-48) created by abolitionists who believed in political action to further antislavery goals. In opposition to William Lloyd Garrison and his followers (who scorned political activity as both futile and sinful in the battle to end slavery), a group of abolitionists met in Warsaw, New York, to organize the Liberty Party. They nominated James G. Birney, a Kentuckian and former slaveholder, for president. The party's first national convention took place at Albany, New York, on April 1, 1840, when Birney's nomination was confirmed.
