Asante, Dahomey and Oyo grew as the trade reached its peak

Between 1650 and 1850 the political map of the Gold Coast and the Bight of Benin was redrawn while Atlantic slaving climbed to its historical peak. The Asante confederacy came to dominate the western half of the region. To the east the kingdom of Dahomey and the Oyo empire became the major powers. These were large organised states with standing armies, tax systems and courts, and their expansion supplied the administrative machinery through which Akan, Ewe and later Yoruba speakers were taken, marched to the coast and sold. The traffic was conducted through African states that grew powerful by conducting it. One exception stands out. The kingdom of Benin, west of the Niger, never became a significant participant, which demonstrates that the choice was available to a state strong enough to make it. People deported from this coast carried their languages into the Americas, and the Rada rite of Haitian Vodou takes its name from Allada, a kingdom on this stretch of the Bight of Benin.

Arrested in 1758 and sentenced to burn, Makandal was taken to the square in front of the church at Cap-Francais. Accounts agree that he got clear of the flames, in front of a crowd that had come to watch him die. He was retaken and executed shortly afterwards. What the colony remembered was the leap. Haitian painters have returned to the scene since, showing the rebellious slave with magical powers astonishing the spectators, and the episode went on troubling masters and administrators for years after the man himself was ash. For the enslaved population the reading was straightforward: fire did not hold him, so the power he claimed was real, and the authorities that had promised a public death had failed to deliver one in front of witnesses. Executions are performed in order to be seen. This one was seen, and it taught the opposite of what it was staged to teach.

In March and April 1848 Faustin Soulouque, then president of Haiti, broke the political families of the south. The trigger was the killing of Celigny Ardouin, a former deputy accused of conspiring against the government. The fighting reached Port-au-Prince and ended in the massacre of members of several southern households. More than seven hundred surviving relatives took shelter in the British legation. In one incident men hunting refugees came to the consul's steps and found a Union Jack laid across them, and none of them would cross it. Minutes before the killing started, Soulouque had sent a note to the British consul Ussher at the palace promising that all foreigners were under his protection. Ussher saw the events and wrote that the object was to strike terror into the respectable mulattoes whom Soulouque had always taken for his enemies. Afterwards Haitians left for Jamaica in numbers larger than any earlier wave of the decade.

When English forces took Jamaica in 1655, observers described the Spanish inhabitants they found there as a debased and degenerate race. The phrase was doing a job. Spaniards born in the Caribbean, several generations away from Europe and mixed with Indigenous and African ancestry, were reclassified as something less than European, and a people who have degenerated can be dispossessed without the awkwardness of taking land from equals. British historians later applied the same description to the Spanish proprietors of Hispaniola, where an argument for expansion needed the same footing under it. The vocabulary outlived its first use. It was aimed at Spaniards in the seventeenth century and at Haitians in the nineteenth and twentieth, and the structure never varied: establish that the present occupants are incapable, and the transfer of their territory reads as a service performed for them. American officers wrote in exactly that register when they landed at Port-au-Prince in 1915.
