For now slavery was also invented. To the barbarian of the lower stage a slave was of no use. The American Indians, therefore, treated their vanquished enemies in quite a different way from nations of a higher stage. The men were tortured or adopted as brothers into the tribe of the victors. The women were married or likewise adopted with their surviving children. The human labor power at this stage does not yet produce a considerable amount over and above its cost of subsistence. But the introduction of cattle raising, metal industry, weaving and finally agriculture wrought a change. Just as the once easily obtainable wives now had an exchange value and were bought, so labor power was now procured, especially since the flocks had definitely become private property. The family did not increase as rapidly as the cattle. More people were needed for superintending; for this purpose the captured enemy was available and, besides, he could be increased by breeding like the cattle.
Such riches, once they had become the private property of certain families and augmented rapidly, gave a powerful impulse to society founded on the pairing family and the maternal gens. The pairing family had introduced a new element. By the side of the natural mother it had placed the authentic natural father who probably was better authenticated than many a "father" of our day. According to the division of labor in those times, the task of obtaining food and the tools necessary for this purpose fell to the share of the man; hence he owned the latter and kept them in case of a separation, as the women did the household goods. According to the social custom of that time, the man was also the owner of the new source of existence, the cattle, and later on of the new labor power, the slaves. But according to the same custom, his children could not inherit his property, for the following reasons: By maternal law, i. e., while descent was traced only along the female line, and by the original custom of inheriting in the gens, the gentile relatives inherited the property of their deceased gentile relative. The wealth had to remain in the gens. In view of the insignificance of the objects, the property may have gone in practice to the closest gentile relatives, i. e., the consanguine relatives on the mother's side. The children of the dead man, however, did not belong to his gens, but to that of their mother. They inherited first together with the other consanguine relatives of the mother, later on perhaps in preference to the others. But they could not inherit from their father, because they did not belong to his gens, where his property had to remain. Hence, after the death of a cattle owner, the cattle would fall to his brothers, sisters and the children of his sisters, or to the offspring of the sisters of his mother. His own children were disinherited.
In the measure of the increasing wealth man's position in the family became superior to that of woman, and the desire arose to use this fortified position for the purpose of overthrowing the traditional law of inheritance in favor of his children. But this was not feasible as long as maternal law was valid. This law had to be abolished, and it was. This was by no means as difficult as it appears to us to-day. For this revolution—one of the most radical ever experienced by humanity—did not have to touch a single living member of the gens. All its members could remain what they had always been. The simple resolution was sufficient, that henceforth the offspring of the male members should belong to the gens, while the children of the female members should be excluded by transferring them to the gens of their father. This abolished the tracing of descent by female lineage and the maternal right of inheritance, and instituted descent by male lineage and the paternal right of inheritance. How and when this revolution was accomplished by the nations of the earth, we do not know. It belongs entirely to prehistoric times. That it was accomplished is proven more than satisfactorily by the copious traces of maternal law collected especially by Bachofen. How easily it is accomplished we may observe in a whole series of Indian tribes, that recently passed through or are still engaged in it, partly under the influence of increasing wealth and changed modes of living (transfer from forests to the prairie), partly through the moral pressure of civilization and missionaries. Six out of eight Missouri tribes have male descent and inheritance, while only two retain female descent and inheritance. The Shawnees, Miamis and Delawares follow the custom of placing their children into the male gens by giving them a gentile name belonging to the father's gens, so that they may be entitled to inherit. "Innate casuistry of man, to change the objects by changing their names, and to find loopholes for breaking tradition inside of tradition where a direct interest was a sufficient motive." (Marx.) This made confusion worse confounded, which could be and partially was remedied alone by paternal law. "This seems to be the most natural transition." (Marx.) As to the opinion of the comparative jurists, how this transition took place among the civilized nations of the old world—although only in hypotheses—compare M. Kovalevsky, Tableau des origines et de l'évolution de la famille et de la propriété, Stockholm, 1890.
The downfall of maternal law was the historic defeat of the female sex. The men seized the reins also in the house, the women were stripped of their dignity, enslaved, tools of men's lust and mere machines for the generation of children. This degrading position of women, especially conspicuous among the Greeks of heroic and still more of classic times, was gradually glossed over and disguised or even clad in a milder form. But it is by no means obliterated.
The first effect of the established supremacy of men became now visible in the reappearance of the intermediate form of the patriarchal family. Its most significant feature is not polygamy, of which more anon, but "the organization of a certain number of free and unfree persons into one family under the paternal authority of the head of the family. In the Semitic form this head of the family lives in polygamy, the unfree members have wife and children, and the purpose of the whole organization is the tending of herds in a limited territory." The essential points are the assimilation of the unfree element and the paternal authority. Hence the ideal type of this form of the family is the Roman family. The word familia did not originally signify the composite ideal of sentimentality and domestic strife in the present day philistine mind. Among the Romans it did not even apply in the beginning to the leading couple and its children, but to the slaves alone. Famulus means domestic slave, and familia is the aggregate number of slaves belonging to one man. At the time of Gajus, the familia, id est patrimonium (i. e., paternal legacy), was still bequeathed by testament. The expression was invented by the Romans in order to designate a new social organism, the head of which had a wife, children and a number of slaves under his paternal authority and according to Roman law the right of life and death over all of them. "The word is, therefore, not older than the ironclad family system of the Latin tribes, which arose after the introduction of agriculture and of lawful slavery, and after the separation of the Aryan Itali from the Greeks." Marx adds: "The modern family contains the germ not only of slavery (servitus), but also of serfdom, because it has from the start a relation to agricultural service. It comprises in miniature all those contrasts that later on develop more broadly in society and the state."
Such a form of the family shows the transition from the pairing family to monogamy. In order to secure the faithfulness of the wife, and hence the reliability of paternal lineage, the women are delivered absolutely into the power of the men; in killing his wife, the husband simply exercises his right.
With the patriarchal family we enter the domain of written history, a field in which comparative law can render considerable assistance. And here it has brought about considerable progress indeed. We owe to Maxim Kovalevsky (Tableau etc. de la famille et de la propriété, Stockholm, 1890, p. 60-100) the proof, that the patriarchal household community, found to this day among Serbians and Bulgarians under the names of Zádruga (friendly bond) and Bratstvo (fraternity), and in a modified form among oriental nations, formed the stage of transition between the maternal family derived from group marriage and the monogamous family of the modern world. This seems at least established for the historic nations of the old world, for Aryans and Semites.
The Zádruga of southern Slavonia offers the best still existing illustration of such a family communism. It comprises several generations of the father's descendants, together with their wives, all living together on the same farm, tilling their fields in common, living and clothing themselves from the same stock, and possessing collectively the surplus of their earnings. The community is managed by the master of the house (domácin), who acts as its representative, may sell inferior objects, has charge of the treasury and is responsible for it as well as for a proper business administration. He is chosen by vote and is not necessarily the oldest man. The women and their work are directed by the mistress of the house (domácica), who is generally the wife of the domácin. She also has an important, and often final, voice in choosing a husband for the girls. But the highest authority is vested in the family council, the assembly of all grown companions, male and female. The domácin is responsible to this council. It takes all important resolutions, sits in judgment on the members of the household, decides the question of important purchases and sales, especially of land, etc.
It is only about ten years since the existence of such family communism in the Russia of to-day was proven. At present it is generally acknowledged to be rooted in popular Russian custom quite as much as the obscina or village community.
It is found in the oldest Russian code, the Pravda of Jaroslav, under the same name (vervj) as in the Dalmatian code, and may also be traced in Polish and Czech historical records.
