West Central Africa supplies more than half of Saint Domingue's arrivals

Between 1750 and 1775 the sources of Saint Domingue's captive population shifted decisively. Of 218,800 people recorded as landed in the colony in those years, 122,586 came from West Central Africa and Saint Helena, fifty six per cent of the total. The Bight of Benin supplied 52,911 and Senegambia and the offshore Atlantic 8,991, which no longer even made it the third largest source. Earlier in the century the balance had run the other way, with Senegambia a leading supplier and West Central Africa a distant third. Two developments explain the reversal. Governments in the Senegambia region grew stronger and more centralised and shut down the raiding that had fed the market there. In the Kongo region kingship stayed fractured and armed force remained the ordinary way of settling political disputes, so the flow of captives grew as the region came apart.

Francois Makandal, a Muslim from Guinea, became the best known of the maroon leaders in 1757. He prophesied that the white masters would be wiped out. He spread terror among them by preparing poisons that killed slowly, and he supplied rebellious slaves with talismans called garde-corps, which were held to make the wearer invulnerable to weapons and to remove all fear of white people. Several groups of maroons were said to be under his command. His name outlived him in the language of the colony. Makandal became the general word in Saint-Domingue for a talisman or a poison, and later for the ceremonies in which such charms were made. That linguistic afterlife is the measure of what he achieved. A man who has been executed can still be a working category in the vocabulary of the people who executed him, and every planter who used the word was repeating his name without meaning to.

Poison prosecutions in Virginia were rare before the law of 1748: five cases in the whole stretch from 1730 to 1748. Then they climbed to thirty in the 1750s, fifty six in the 1760s and sixty five in the 1770s, before dropping to twenty three in the 1780s. Across the eighteenth century more enslaved people were tried in Virginia for poisoning than for any crime except theft. After 1748 the phrase poisonous medicines, which had appeared in neither law nor cases before that year, turns up in a majority of them until the end of the century, and the number of cases naming no victim at all rose in step with it. Of the twenty seven cases in Brunswick and Cumberland counties in these decades, just over half involved medical practitioners. The statute that created the offence created the wave of prosecutions that followed it.

An enslaved woman named Quamina died in 1775 on a Suriname plantation after weeks of pain in her belly. Everyone on the estate went together to the overseer, H. C. Dorfeld, accused Quacoe of poisoning her and asked that he be put in irons. Quacoe was the head carpenter and, judging from the letter Dorfeld sent the court, a healer too; the others believed he could have cured Quamina and had refused. At the funeral in the slave quarters the crowd ran behind the coffin and flung it against Quacoe's door. They searched his house for evidence and found none. They washed the body and gave him the water to drink, on the understanding that a guilty man would die of it, and he drank it willingly. Later four men beat him, joined by several young women with sticks, and he reached the main house covered in blood. The court punished the four and let Quacoe go.
