Андрей Тихомиров, The concept of matriarchy

Matriarchy is an early period in the history of the primitive communal system, characterized by the equal and then predominant position of women in the economy and society. The term "matriarchy" also refers to the social system of the early period of the primitive communal system. All the peoples of the globe have passed the stage of matriarchy, coming immediately after the epoch of the primitive herd and dating archaeologically to the late Paleolithic.
