Under one crown, three quarters of the trade sails Portuguese

From 1580 to 1640 Spain and Portugal were ruled by the same king. Across those sixty years more than 75 percent of everyone carried over the Atlantic in the slave trade travelled in Portuguese ships. Spain held the American empire and the demand for labour. Portugal held the African forts, the contacts and the vessels. The union let one supply the other without the machinery of a foreign contract, and the asiento, the licence to deliver captives into Spanish America, sat in Portuguese hands. Most of those ships were working for Brazil. They left Brazilian ports, crossed to Angola, and returned to the sugar coast, so the largest share of the entire Atlantic traffic in this period touched Europe at neither end. When the union broke in 1640 the arrangement broke with it, and Dutch, English and French carriers moved into the space. The Atlantic slave trade had one dominant flag for six decades, and it was not the flag of the empire doing the buying.

In 1605 and 1606 the colonial authorities in Santo Domingo destroyed the settlements along the northern and western coasts of Hispaniola. The aim was to stop the contraband trade that those towns carried on with foreign shipping. The result was a further fall in a population that was already shrinking, since many Spaniards on the island left for the American mainland, drawn by stories of rich indigenous kingdoms and by a crown that now cared more about its continental colonies. New settlers from Spain saw no reason to come to the Caribbean. The nineteenth century Dominican historian Jose Gabriel Garcia, a doctrinaire liberal, called the operation a violent answer to a problem the government could not win by law, and held that a freer trade policy would have prevented it. He also drew the longer line. Emptying the north and west of the island opened the door for French colonists to settle there.

Guaman Poma de Ayala was a Quechua living in Tawantinsuyu while the territory of the Inca was being replaced by the Viceroyalty of Peru. His Nueva coronica y buen gobierno, of 1616, addressed Philip the Third of Spain directly, and its last forty or so drawings are given over to labour in Tawantinsuyu, a conception of work that had nothing to do with the European medieval idea of labour and was being displaced by it. He wrote from inside the world under discussion. The Spanish theologian Francisco de Vitoria, arguing at the same period about the rights of the Indians, wrote from Salamanca about people he had never met, and de Vitoria has been praised, criticised and enthroned as a founder of international law ever since. Guaman Poma was ignored until recently, and his book is still treated as a document rather than as a political treatise. Both men wrote about the same conquest.

The first small party of French settlers reached Tortuga, the island lying off the north coast of what is now Haiti, in 1629. They were pirates, cattle rustlers and buccaneers who lived by raiding Spanish shipping and by hunting the wild cattle that roamed the larger island. Hides were their trade and their food. From that base they fought the Spanish and gradually pushed onto Hispaniola itself, where they began planting cacao, cotton and indigo. Farming was what let the settlements hold their ground, since a camp that grows food does not have to move. The fort on Tortuga became the pivot of the fighting between European powers for the island. Nothing about this beginning suggested a colony. Within seventy years the western third of Hispaniola would be French territory, and within a hundred and sixty it would be the most profitable piece of ground in the Atlantic world.
