Even the briefest account of the family life of the Negro must include a consideration of the history back of the present Negro family. This history naturally divides itself into three periods: Africa, slavery, and freedom. While the African period, it must be remembered, does not claim our attention because an unbroken social tradition still affects the present formation of the Negro family -although traces of the African tradition were detected in marriage ceremonies near the opening of the present century —it is necessary to call attention to this period because of subsequent events. In Africa the Negro lived under regulated sex relations which were adapted to his social and physical environment. It was through the destruction in America of these institutionalized sex relations that slavery was able to bring about complete subordination.
