Between 1680-1688 England operated 249 slave ships; from 1713, for twenty years, 15,000 slaves were annually shipped to America; by 1786, England had brought over 97,000 slaves. Though Liverpool was the chief port for this trade, Bristol was a close second. New England was not slow in this nefarious system – by 1725 it had become the center of the transatlantic slave trade. After the Pequot tribe was vanquished in the latter 1630s, Puritans sold captive men, women and children into West Indies slavery.
Colonial Versus British Law
“Slavery [in American colonies] simply evolved in practice, as a custom, and then received statutory recognition. Actually, the process of “recognition” was implicit, involving no articulation of first principles. In 1636 the governor and council of Barbados decreed that “Negroes and Indians, that come here to be sold, should serve for Life, unless a Contract was made before to the contrary.” A Rhode Island statute of 1652 cited “the common course practiced among English men to buy Negars, to that end that they may have them for service or slaves forever.”
The famous Fundamental Constitutions, drawn up by John Locke and the Earl of Shaftesbury in 1669 for the nascent South Carolina colony, guaranteed that “Every Freeman of South Carolina shall have absolute power and authority over Negro Slaves.” [And] the reality is that slavery was principally acknowledged in law by an extensive set of police measures.
Chief Justice Sir John Holt reasoned that “as soon as a negro comes to England, he becomes free; one may be a villein in England, but not a slave.” Yet in an earlier opinion he concluded to the contrary that Africans were indeed commodities; yet in no case did the common law ever meddle with, ratify, reject or otherwise directly address slavery in the colonies, as opposed to England, other than as the apparent custom of the colonies.
In fact, there are many reported cases concerning the English slave-trading monopoly, indebted tobacco or sugar planters, the duties charged on various plantation commodities, and trade to Africa and America, all matters whose circumstances frequently involved black slaves.”
