Indentured servitude was a system of cheap or free labor that became very popular in the colonies. In this system, an individual signed an indenture or contract of working for some years in exchange for some benefit that was usually transportation to the New World along with food and shelter when he or she arrived.
This means individuals who accept this contract had to pay back with work for the benefits received.
