With increasing civilization sexual intercourse among brothers and sisters is put under the ban, and this is gradually extended to all collateral relatives on the mother’s side. A new consanguine family, the gens, is evolved that originally consists of natural and remote sisters and their children, together with their natural or remote brothers on the mother’s side. The gens has a common ancestress to whom the groups of female generations trace their descent. The men do not belong to the gens of their wives, but to the gens of their sisters. But the children of these men belong to the gens of their mothers, because descent is traced from the mother. The mother is considered the head of the family. Thus the matriarchate was evolved that for a long time constituted the foundation of family relations and inheritance. While the maternal law prevailed, women had a voice and vote in the councils of the gens, they helped to elect the sachems and leaders and to depose them. When Hannibal formed an alliance with the Gauls against the Romans, he decided that in case disputes should arise among the allies, the Gallic matrons should be intrusted with the mission of arbitrating; so great was his confidence in their impartiality. Of the Lycians who recognized maternal law Herodotus tells us: “Their customs are partly Cretan and partly Carian. But they have one custom that distinguishes them from all other nations in the world. If you ask a Lycian who he is, he will tell you his name, his mother’s name, and so on in the line of female descent. Moreover, when a free woman marries a slave, her children remain free citizens. But if a man marries a foreign woman or takes unto himself a concubine, his children are deprived of all civic rights, even though he be the most eminent man in the state.” At that time “matrimonium” was spoken of instead of “patrimonium,” “mater familias” was said instead of “pater familias,” and one’s native country was referred to as the motherland. Just as the earlier family forms, the gens was founded on the common ownership of property, that is, it was a communistic form of society. Woman was the leader and ruler in this kinship organization and was highly respected, her opinion counting for much in the household as well as in the affairs of the tribe. She is peacemaker and judge, and discharges the duties of religious worship as priestess.
