Consequently, men used to consider children, as well as themselves, the children of women. The lineage was constructed by reference to mothers, and not by reference to fathers. Men were considered barren and unproductive and after marriage they lived in the tribe of the woman like parasites, and the woman needed him only for his company and his physical strength. This period according to sociologists, is known as the matriarchal period.
It was not long before man came to know of his part in the birth of children and identified himself as the real person to whom his children were to be attributed. From that time on, he brought woman under his control, and took the position of the head of the family; the patriarchal period, as it is called, began. In that age, too, marriage between blood relations was not considered admissible, and man was obliged to select his spouse from some other tribe and bring her to his own tribe.
As there was always a state of conflict and hostility among tribes, the selection of spouse was by means of abduction, in other words, a young man abducted the girl of his choice from another tribe. Gradually, peace instead of hostility reigned, and the different tribes could peacefully live together.
At that point the custom of abduction became unnecessary, and in order to get the girl of his choice man used to bind himself to the service of the father of the girl and in lieu of the services rendered by the would-be son-in-law, the father of the girl gave his daughter to him, and then he would bring that girl to his tribe.
Eventually the economic situation improved, and man reached the conclusion, that, instead of working for years for the father of the bride, it was preferable to present a worthy gift to him at the time of marriage, and thus obtain his daughter from him. He begun to do this, and from here the dower came into existence. Thus according to the sociologist, in the first period, man lived as a parasite and as an attendant on woman. In that period the woman used to rule over the man.
In the subsequent period, when the power felt into the hands of man, he abducted the woman from her tribe. In the third period, in order to obtain the woman of his choice, man used to go to the father of the woman and work several years for him. In the fourth period, man paid an amount of money as a ‘present’ to the father of the woman, and from here the custom of the dower began.
