In the 17th century Europeans began to establish settlements in the Americas. The division of the land into smaller units under private ownership became known as the plantation system. Starting in Virginia the system spread to the New England colonies. Crops grown on these plantations such as tobacco, rice, sugar cane and cotton were labour intensive. Slaves were in the fields from sunrise to sunset and at harvest time they did an eighteen hour day. Women worked the same hours as the men and pregnant women were expected to continue until their child was born.
European immigrants had gone to America to own their own land and were reluctant to work for others. Convicts were sent over from Britain but there had not been enough to satisfy the tremendous demand for labour. Planters therefore began to purchase slaves. At first these came from the West Indies but by the late 18th century they came directly from Africa and busy slave-markets were established in Philadelphia, Richmond, Charleston and New Orleans. Hope this Helps!
The plantation system helped plantation owners because they didn't have to take care of their crops, and the slave trade, because it provided them with business, but it obviously hurt the slaves because there was a higher demand for them and because they were often treated terribly.
