Answer:
Slavery and enslavement are both the state and the condition of being a slave,[1][2] who is someone forbidden to quit their service for another person (a slaver), while treated as property.[3] Slavery typically involves the enslaved person being made to perform some form of work while also having their location dictated by the slaver. Historically, when people were enslaved, it was often because they were indebted, or broke the law, or suffered a military defeat, and the duration of their enslavement was either for life or for a fixed period of time after which freedom was granted.[4] Individuals, then, usually became slaves involuntarily, due to force or coercion, although there was also voluntary slavery to pay a debt or obtain money for some purpose. In the course of human history, slavery was a typical feature of civilization,[5] and legal in most societies, but it is now outlawed in all countries of the world, except as punishment for crime.[6][7]
