Master-Slave Relations Slave women were forced to comply with sexual advances by their masters on a very regular basis. Consequences of resistance often came in the form of physical beatings; thus, an enormous number of slaves became concubines for these men. Most often the masters were already bound in matrimony, which caused tension and hatred between the slave and the mistress of the house. Many "mulatto" or racially mixed children also resulted from these relations. Because the "status of the child" followed that of his or her mother, the child of a white man would not be freed based upon patriarchal genealogy. These children also became a sore reminder for the mistress of her husbands infidelity.
