Perth Amboy existed as a landing place because New York taxed imports

Enslaved Africans first reached the Middle Colonies under Dutch rule, before 1667, landing mostly in what would become New York. Across the period to 1775 about ninety percent of the captives brought into the region came in through New York City or through Perth Amboy in New Jersey, and the remainder were landed at Philadelphia. Sixty percent travelled on vessels owned by New York merchants, which sets the region apart from most of British America, where British owned ships did the carrying. Perth Amboy was used for one reason. New York imposed higher customs duties on arriving captives, and a trader who unloaded across the bay in New Jersey paid less. People were moved between jurisdictions to shave a tax bill, and the paperwork generated by that saving is a large part of why the record of these arrivals exists at all.

On 30 October 1665 the army of the Kongo met the Portuguese forces of Loanda at Ambuila and was destroyed. The king, Antonio I, died there, along with his son, the dukes of Mbamba, Mbata, Nsundi and Gorimba, the marquess of Mpemba, and ninety five title holders altogether, as well as a Capuchin who had come against his prefect's orders. Antonio had brought his crown, his sceptre and the royal archives with him. Everything was lost. Angola's expansion had made a strong independent kingdom to its north unacceptable, and Angola's economy was the traffic in slaves feeding Brazil. The kingdom that had existed since Afonso I, and the Christian ruling class that had formed inside it, never recovered. Succession disputes multiplied between rival clans, and in 1678 one of the contending armies sacked Mbanza Kongo itself. The churches and palace were left in ruins and nobody lived in the city for twenty five years.

The Code Noir of 1685 ordered that every enslaved person in the French islands be baptised and instructed in the Catholic religion, and required a planter buying newly arrived Africans to notify the governor within eight days so that instruction and baptism could be arranged. The same text forbade the public exercise of any other religion and directed that offenders be punished as rebels. Marriage of the enslaved was prescribed as well, and the Church pressed it through the following century. The purpose of this apparatus was the quiet reproduction of slavery over a long stretch of time. Masters and administrators watched for anything that might interrupt it: abortion, infanticide, and above all flight from the plantation. Alongside the whip, which had never been sufficient on its own, the colony now had a machine for supervising the few hours of rest a slave was allowed.

Louis XIV of France and William III of England closed their war in 1697 by exchanging territory neither of them had ever seen. The Treaty of Ryswick was a general settlement covering Europe, North America and the Caribbean, and among its terms Spain gave up the western third of Hispaniola to France. Spain had held nominal title to the whole island for two centuries and had governed the western end of it hardly at all, its own settlers having withdrawn eastward long before. France received the piece that turned out to matter. Over the following century Saint-Domingue produced revenue on a scale that is hard to state without sounding careless. By the 1780s the colony was worth more to France, in trade and customs receipts, than the thirteen British colonies of North America were worth to Britain. One third of one Caribbean island out-earned the eastern seaboard of a continent. That is the wealth the enslaved population created, and it is the wealth they carried out of the empire with them.
