Answer:
The two main kinds of slavery were indentured and chattel.
Step-by-step explanation:
Slavery is a situation in which one person (the slave) is the property of another (the master). Thus understood, it constitutes a particular form of production relationship, typical of a certain level of development of the productive forces in the evolution of the economy.
There were two main forms of slavery: the indentured servitude, which consisted of a temporary contract of servitude, in which the indentured servant worked free for a certain time, in exchange for a certain benefit; and the chattel slavery, by which the slave was wholly owned by his master, without any kind of rights.
