By 1689, few African slaves had been introduced to Virginia and elsewhere by British, Dutch, French slavers, though this changed radically in the next seventy years – by 1760 the black race formed fully two-fifths of the entire Southern population. The increasing supply of Africans certainly fixed the plantation system on the South as part of the British colonial labor system.

Fixing Blame for African Slaves
“So far as the [colonial] Southern tidewater is concerned, the increase in population came largely through the involuntary immigration of African Negroes. During the seventeenth century . . . British merchants and their government were organizing as never before for the exploitation of the slave trade.
The prosperity of the Royal African Company stimulated competition, and before long “separate traders” from England and [New England] broke down the company’s monopoly. In 1713 the British slave-traders gained a great advantage over Dutch and French rivals by the Asiento agreement, giving them the privilege of supplying slaves to the Spanish colonial market.
There are no comprehensive statistics; but in 1734 it was estimated that about 70,000 slaves annually were exported from Africa to the New World.
The responsibility for slavery in the English colonies must be distributed widely. British merchants, the imperial government, which defeated efforts on the part of colonial assemblies to check the trade, [and] New England traders . . . each group must take its share.
Peter Fontaine, an Anglican clergyman of Huguenot stock, spoke of it as the “original sin and curse of the country,” but urged that when the colonists tried to restrict importation, their acts were commonly disapproved in England.
Besides, he argued, the Negroes had been first enslaved in Africa by men of their own color . . . Efforts were made to Christianize and educate the Negroes, and the Anglican missionaries were expected to make this part of their work.”
