At the time of the discovery, most of the Siouan tribes had apparently passed into gentile organization, though vestiges of clan organization were found—e.g., among the best-known tribes the man was the head of the family, though the tipi usually belonged to the woman. Thus, as defined by institutions, the stock was just above savagery and just within the lower stages of barbarism. Accordingly the governmental functions were hereditary in the male line, yet the law of heredity was subject to modification or suspension at the will of the group, commonly at the instance of rebels or usurpers of marked prowess or shrewdness. The property regulations were definite and strictly observed; as among other barbarous peoples, the land was common to the tribe or other group occupying it, yet was defended against alien invasion; the ownership of movable property was a combination of communalism and individualism delicately adjusted to the needs and habits of the several tribes— in general, evanescent property, such as food and fuel, was shared in common (subject to carefully regulated individual claims), while permanent property, such as tipis, dogs, apparel, weapons, etc, was held by individuals. As among other tribes, the more strictly personal property was usually destroyed on the death of the owner, though the real reason for the custom—the prevention of dispute—was shrouded in a mantle of mysticism. Although of primary importance in shaping the career of the Siouan tribes, the marital institutions of the stock were not specially distinctive. Marriage was usually effected by negotiation through parents or elders; among some of the tribes the bride was purchased, while among others there was an interchange of presents. Polygyny was common; in several of the tribes the bride’s sisters became subordinate wives of the husband. The regulations concerning divorce and the punishment of infidelity were somewhat variable among the different tribes, some of whom furnished temporary wives to distinguished visitors. Generally there were sanctions for marriage by elopement or individual choice. In every tribe, so far as known, gentile exogamy prevailed—i.e., marriage in the gens was forbidden, under pain of ostracism or still heavier penalty, while the gentes intermarried among one another; in some cases intermarriage between certain tribes was regarded with special favor. There seems to have been no system of marriage by capture, though captive women were usually espoused by the successful tribesmen, and girls were sometimes abducted. In general it would appear that intergentile and intertribal marriage was practiced and sanctioned by the sages, and that it tended toward harmony and federation, and thus contributed much toward the increase and diffusion of the great Siouan stock.
