The 1804 Haiti massacre was a massacre carried out against the remaining white population of native French people and French Creoles (or Franco-Haitians) in Haiti by Haitian soldiers by the order of Jean-Jacques Dessalines who had decreed that all those suspected of conspiring in the acts of the expelled army should be put to death.[1] Throughout the nineteenth century, these events were well known in the United States where they were referred to as "the horrors of St. Domingo" and particularly polarized Southern public opinion on the question of the abolition of slavery.[2][3]
The massacre, which took place in the entire territory of Haiti, was carried out from early February 1804 until 22 April 1804, and resulted in the deaths of between 3,000 and 5,000 men and women of all ages.[4]
Squads of soldiers moved from house to house, torturing and killing entire families.[5] Even whites who had been friendly and sympathetic to the black population were imprisoned and later killed.[6] A second wave of massacres targeted white women and children.[6]
