By the 1820s, the controversy surrounding the Missouri Compromise had quieted down considerably, but was revived by a series of events near the end of the decade. Serious debates over abolition took place in the Virginia legislature in 1829 and 1831. In the North discussion began about the possibility of freeing the slaves and then resettling them back in Africa (a proposal that led to the founding of Liberia). Agitation increased with the publication of David Walker's Appeal to the Colored Citizens of the World in 1829, Nat Turner's slave rebellion in 1831, and Andrew Jackson's handling of the nullification crisis that same year. According to Louis Ruchame, "The Turner rebellion was only one of about 200 slave uprisings between 1776 and 1860, but it was one of the bloodiest, and thus struck fear in the hearts of many white southerners. Nat Turner and more than 70 enslaved and free blacks spontaneously launched a rebellion in Southampton County, Virginia, in August 1831. They moved from farm to farm, indiscriminately killing whites along the way and picking up additional slaves. By the time the militia put down the insurrection, more than 80 slaves had joined the rebellion, and 60 whites lay dead. While the uprising led some southerners to consider abolition, the reaction in all southern states was to tighten the laws governing slave behavior
