Kinsmen of Another Kind - Gary Clayton Anderson - Bog

In Kinsmen of Another Kind, Anderson shows how the Dakota concept of kinship affected the tribe's complex relationships with the whites. The Dakota were obligated to help their relatives by any means possible. Traders who were adopted or who married into the tribe gained from this relationship -- but had reciprocal responsibilities. After the 1820s, the trade in furs declined, more whites moved into the territory, and the Dakota became more economically dependent on the whites. When American traders and officials failed to fulfill their obligations, many Dakotas finally saw the whites as enemies to be driven from Minnesota.
