The African people of Haiti derived from various areas, spanning from Senegal to the Congo. Most of which were brought from West Africa, with a considerable number also brought from Central Africa. Some of these groups include those from the former Kongo kingdom (Kongo), (Igbo Benin (Ewe and Yoruba) and Togo land. Others in Haiti were brought from Senegal, Guinea (imported by the Spanish since the sixteenth century and then by the French), Sierra Leone, Windward Coast, Angola, Cameroon, Nigeria, Ghana, Togo, and Southeast Africa (such as the Bara tribesmen of Madagascar, who were brought to Haiti in the eighteenth century). Haitian culture is very tied to West African culture, especially that of pre-colonialism Benin, Haitian Vodou mostly has origins from the original West African Vodun of Benin and the French-based Haitian Creole language has influences from several African languages including the Fon language. At the time of the Haitian Revolution war, an event that involved the eradication of whites (mostly French) in Haiti, many of the blacks in Haiti were African-born and had no non-African admixture. This was because the average African slave in colonial Haiti had a short life span and France continuously imported thousands of Africans yearly to keep the slave population up, by 1790 there were nearly 600,000 slaves, outnumbering whites about 20 to 1.
