The revolt of enslaved Hatians against their white slave owners, which began in 1791 and lasted until 1801, was a primary source of fuel for both enslaved people and abolitionists arguing for the freedom of Africans in the U.S. In the 1833 edition of "Nile's Weekly Register" it is stated that freed Black people in Haiti were better off than their Jamaican counterparts, and the positive effects of American Emancipation are alluded to throughout the paper. These anti-slavery sentiments were popular among both white abolitionists and African-American slaves. Enslaved people rallied around these ideas with rebellions against their masters as well as white bystanders during the Denmark Vesey Conspiracy of 1822 and the Nat Turner Rebellion of 1831. Leaders and plantation owners were also very concerned about the consequences Haiti's revolution would have on early America. Thomas Jefferson, for one, was wary of the "instability of the West Indies", referring to Haiti.
