Chattel slavery, also called traditional slavery, is so named because people are treated as the chattel (personal property) of the owner and are bought and sold as commodities.
Typically, under the chattel slave system, slave status was imposed on children of the enslaved at birth.
Examples of sexual slavery, often in military contexts, include detention in "rape camps" or "comfort stations," "comfort women", forced "marriages" to soldiers and other practices involving the treatment of women or men as chattel and, as such, violations of the peremptory norm prohibiting slavery.
Forced marriages or early marriages are often considered types of slavery.
In other areas, slavery (or unfree labour) continues through practices such as debt bondage, the most widespread form of slavery today, The English word slave comes from Old French sclave, from the Medieval Latin sclavus, from the Byzantine Greek σκλάβος, which, in turn, comes from the ethnonym Slav, because in some early Medieval wars many Slavs were captured and enslaved.
