Concubinage is an interpersonal and sexual relationship between two people in which the couple does not want to, or cannot, enter into a full marriage. Concubinage and marriage are often regarded as similar, but mutually exclusive.
During the early stages of European colonialism, administrators often encouraged European men to practice concubinage to discourage them from paying prostitutes for sex (which could spread venereal disease) and from homosexuality. Colonial administrators also believed that having an intimate relationship with a native woman would enhance white men's understanding of native culture and would provide them with essential domestic labor. The latter was critical, as it meant white men did not need wives from the metropole, and thus did not require a family wage. Colonial administrators eventually discouraged the practice when these liaisons resulted in offspring who threatened colonial rule by producing a mixed-race class. This political threat eventually prompted colonial administrators to encourage white women to travel to the colonies, where they contributed to the colonial project while also reinforcing domesticity and the separation of public and private spheres.
