Most of the workers who worked on the tobacco plantations located in Virginia in the 1600's are mostly indentured servants. Indentured servants are individuals (both men and women) who signed an agreement, also known as "an indenture" in which they agree to work for a certain amount of years in exchange of transportation to Virginia, and once they get to Virginia, other essentials such as food, shelter, and clothing are given to them.
