Slavery was not introduced immediately with the arrival of a handful of Africans on Virginia soil. With plenty of available poor, white workers, those who worked temporarily as indentured servants to pay off their ship's passage to America, the number of blacks imported into the English colonies of North America remained small. Even as late as 1649, only 300 blacks had arrived in Virginia. In addition, for decades following the arrival of those first Africans at Jamestown, blacks were treated as servants, not slaves bound to work for their masters for life.
