Explain what being an indentured servant meant?

An indentured servant, unlike a slave, is someone who owes their owner money and is working to repay their debt, an indentured servant is paid unlike slaves and therefore are not slave, even though the conditions for both slaves and indentured servants are poor, most indentured servants were white as Africans would be sold off into slave labor. Being an Indentured servant means you work until you pay off your debt, and than your "employer" will sometimes give you a plot of land and a farm as payment along with your relieved debts

It mean't a person under contract to work for another person for a definite period of time, usually without pay but in exchange for free passage to a new country. And during the seventeenth century most of the white laborers in Maryland and Virginia came from England as indentured servants.
