Before Slavery became an acceptance in the colonies, indentured servants became common in this region during the early settlement. They remained as an indentured slave from the beginning until 1661.  African slaves brought in America as servants and labourers to help tobacco plantations to prosper and generate wealth.  Indentured servants were not much favoured in later period because they were part of the contract which allowed them to work for four years after reaching in America and set free. The alternative turned towards slavery,  forced to work in the fields with no contract sign for releasing them.
