African slaves were brought to the English colonies to meet the demand for labor.

Explanation:

The first blacks introduced into English North America did not do so as slaves, but as deeded workers, like many of the European immigrants before 1776, who at the end of the contract were free, as wage earners.

However, for the blacks the deed was, too many times, life-long. In 1650 it was almost impossible for them to obtain freedom: the Europeans had begun to value the riches of the New World and needed to exploit them with cheap and submissive labor, and forgetting their liberal origins slipped into slavery. Maryland legalized it in 1634. Delaware in 1636. In 1671 there were already 2,000 black slaves in Virginia (5 percent of the total population). Before 1680 all the English colonies of North America had adopted slavery.
