How is African American slavery compared to serfdom and endeavored servitude?

African American slavery was a system of chattel slavery in which enslaved individuals were considered property to be bought and sold. Serfdom was a system in medieval Europe where serfs were tied to the land they worked and owed labor to a lord. Indentured servitude was a form of temporary labor contract in which individuals worked for a set period in exchange for passage to a new country or payment of debt. Each system had different legal statuses and conditions of labor, but all involved exploitation and lack of freedom for the laborers.
