Jean-Jacques Dessalines (Haitian Creole: Jan-Jak Desalin; French pronunciation: ​[ʒɑ̃ ʒak dɛsalin]; 20 September 1758 – 17 October 1806) was a leader of the Haitian Revolution and the first ruler of an independent Haiti under the 1805 constitution. Under Dessalines, Haiti became the first country to permanently abolish slavery. Initially regarded as governor-general, Dessalines was later named Emperor of Haiti as Jacques I (1804–1806) by generals of the Haitian Revolution Army and ruled in that capacity until being assassinated in 1806. He is regarded as one of the founding fathers of Haiti.
