With the king away on campaign, the queen orders the looters killed

King Afonso of Kongo went east on campaign and left a man named Alvaro Lopes in charge of the capital. Some enslaved people killed their supervisor and began plundering the countryside. Lopes hesitated over punishing them because they belonged to the king and had been bought with money the king had provided. The queen intervened and ordered Lopes to have them killed, telling him that those who kill are killed. He carried it out. Afonso set the whole episode down in a letter to Manuel of Portugal dated 5 October 1514. What matters is who issued the order. Kongo did not make offices hereditary; the king appointed provincial governors and could dismiss them, and the crown itself was elective. In a system built that way, the person holding authority in the capital while the king was in the field was his wife. Elite women in Kongo are usually visible through their patronage of the church, and here one of them is visible through an execution.

By 1514 the indigenous population of Hispaniola stood at about twenty-nine thousand. Estimates of what it had been in 1492 vary widely, from a few hundred thousand to more than a million, and the disagreement among historians is genuine, turning on how much land the islanders farmed and how many people that land could feed. No figure in the range makes the fall look like anything other than a collapse inside one human lifetime. Two forces did it. The first was disease. Smallpox, influenza and measles had circulated in Eurasia and Africa for centuries and the people of the Caribbean carried no resistance to any of them. The second was the labour system. Men were sent to pan gold in river gravel and women were set to work in Spanish fields, which broke up households, stopped the planting of the cassava and maize the islands lived on, and pushed the birth rate down while it pushed deaths up. Famine follows when the farmers are somewhere else.

In 1510 the Spanish crown authorised the shipment of enslaved Africans to Hispaniola and the first of them came ashore. The reason was arithmetic. Colonists had been extracting gold and food from the island using Taino labour under the encomienda system, and the Taino were dying, from overwork, from hunger when their fields went untended, and from smallpox and other diseases against which they had no immunity. The colony's output depended on bodies it no longer had. Africa offered a supply that could be bought and shipped, and Portugal already held the trading posts and the vessels. That decision stood for nearly three hundred years. It moved more than ten million people alive across the Atlantic, and it built the sugar economy that made the western third of this island the most valuable colony in the world. It also assembled, on the same ground, the population that abolished slavery there by force in 1793 and founded Haiti in 1804.

Africans were on the island from about 1500. King Ferdinand sent the first official consignment in 1510, to work the mines and the sugar. Bishop Las Casas argued for the substitution in the hope of sparing the indigenous population, and lived long enough to regret having said it. The Heinls call the result a hecatomb. The system Las Casas helped licence ran for three centuries and consumed millions of lives. Two dates inside this span matter more than the rest. By 1503 enslaved Africans were already going into the mountains and building free settlements there, which makes marronage on this island older than its sugar industry and almost as old as slavery itself. In 1518 Charles the Fifth issued a formal slaving monopoly with an annual ceiling of four thousand captives, many of them taken from the coasts of Dahomey and Guinea. Those coasts became the ancestral ground of the people who took the colony back in 1804.
