““The patriarchal family was only the most recent in a string of 'primary' social organizations, all of which defined woman as a different species due to her unique childbearing capacity. The term family was first used by the Romans to denote a social unit the head of which ruled over wife, children, and slaves - under Roman law he was invested with the rights of life and death over them all; famulus means domestic slave, and familia is the total number of slaves belonging to one man.””
