The National Liberty Party was a minor political party founded in 1840, consisting of abolitionists who broke away from the American Anti-Slavery Society. They believed that the Constitution was an anti-slavery document and used the document to support their efforts. The National Liberty Party’s first national convention took place in Arcade, N.Y., on April 1, 1840.
