Trying to find details on the "Mozambiques" and East Africans in colonial Haiti is, rather difficult. They were largely imported into the colony during the last 2 decades of colonial rule, often being imported at Le Cap, Saint-Marc, and Port-au-Prince. While Jesuit historian Charlevoix mentioned an early presence of Monomotapa and Madagascar slaves in the colony, they were not considered desirable slaves by the French. However, the development of the Mascarenes and the insatiable need for labor in Saint-Domingue made East Africa and Mozambique a supplier of over 20,000 captives to the colony from 1773 until the 1790s. As the above maroon case indicates, some of these "Mozambiques" had even been enslaved in the Mascarenes for a while, learning French (and presumably, Mauritian Creole?) before being brought to Saint-Domingue.
Michel, a Macoua (Makua)
Trying to determine the "nations" of the Mozambiques in Saint-Domingue is difficult. The only two "nations" we have seen explicitly mentioned in the colony are Makua (Macoua, Maquoua) or Maconde (of Tanzania and parts of Mozambique). Despite the appellation, many of the "Mozambiques" came from diverse areas in Southeastern Africa. The Makua may have been a larger proportion of the total, but if the composition of the "Mozambiques" in the Mascarenes is a reliable indication, Saint-Domingue may have included Mondjavoas, Senas, Moussenas, Yambanes, Mouquindos, Maravis, and Niamoeses in addition to Makua and Maconde. This ethnic heterogeneity seems to have been completely lost in the eyes of Saint-Domingue's slaveholders, who should have known the "Mozambiques" were quite different from other Africans yet not a singular group in themselves.
A Mozambique who spoke Portuguese and Spanish
It also appears that some of the "Mozambiques" had spent substantial time in the Portuguese colony or among Lusophones. For instance, the above case of a runaway demonstrates how some "Mozambiques" could speak Portuguese and Spanish. This may explain why some of the "Mozambiques" encountered by Descourtilz were also devout Catholics (in his eyes). They, like some of the "Congo" in Saint-Domingue, were influenced by Roman Catholicism and may have added to the already Christian (or partly Christianized) segment of the enslaved population. Unfortunately, it is difficult to say to what extent these Catholic "Mozambiques" formed a significant part of the "Mozambique" population in Saint-Domingue, but they were conspicuous enough to be noticed by Descourtilz.
4 runaway Makuas. Perhaps the large concentration of "Mozambiques" in some areas favored marronage as they found people from the same or similar ethnolinguistic backgrounds to escape with.
A runaway slave of the Maconde "nation" appears here.
As for East Africans, purchased from Kilwa, Mombasa, Monfiat and Zanzibar, Saint-Domingue received a little over 2000. Vidargent, of the Malingue nation, may be an example of this East African (Tanzanian) presence. The French slave trader, Morice, used the word Malingue to refer to captives purchased from Kilwa. The name may be a corruption of Maningo or Machinga, peoples from the hinterland of Kilwa or the Tanzanian interior. Malingue could also refer to a completely different African "nation" in West or Central Africa, but we thought it interesting that Morice used the same word in the 1770s and an African of that "nation" appeared in the colony around the same time. This presence of captives purchased via the Swahili Coast was on a much smaller scale and, alas, the "nations" of these groups in the colony of Saint-Domingue are not clearly specified or listed in the archive. We know from Moreau de Saint-Mery that captives purchased from Montfiat, Kilwa, and variosu spots on the eastern coast of Africa could be found, including from some closer to the Cape of Good Hope (Natal Africans?).
Sadly, our only somewhat detailed account of "Mozambiques" in colonial Haiti remains the work of Descourtilz. For example, he conversed with a Mirault who owned many Mozambiques, including one who allegedly consumed human blood. Again, it is via Descourtilz that we learn that some of the Mozambiques were Catholics through Portuguese influence. Even more useful is Descourtilz's brief and problematic description of the "Vaudoux" of the Mozambiques. According to him, their "Vaudoux" practice consisted of imploring their "serpent" or "vaudoux" for the favor of their masters, the acquisition of money, to find love or for other wishes. He even described a Mozambique "Vaudou" reunion which allegedly occurred at the Pelerin habitation in Saint-Louis. According to him, the Mozambiques met in a secret spot and as part of their ritual, a child was beaten or severely injured. Since Descourtilz did not witness some of the things he described, he must be used cautiously here. Nonetheless, we may be reading a very biased, incomplete account of diviners and spiritual practices of southeastern African peoples.
After Haitian independence, the presence of "Mozambiques" was noted for some time. For example, a colonel named Louis Mosambique was killed by Petion in Saltrou for what may have been an attempted conspiracy or revolt in 1816. In terms of cultural legacy, it's possible their presence in Haiti was comparable to that of Brazil. They came in large numbers, but far smaller than other groups and therefore their cultural impact may be minimal. Instead, they were more likely to become part of the established culture among the enslaved. Nonetheless, it is both fascinating and horrifying to see the links between the Indian Ocean and Atlantic Ocean for the slave trade to the Mascarenes and the Caribbean.
