This book is a very detailed overview of the Indian Wars fought between 1860 and 1890.
The most interesting point in the book is that, although we group these conflicts under the rubric of “Indian Wars,” Native Americans themselves did not see it that way. Until very late in this period, many tribes saw themselves as distinct units and had no sense of “Indianness” (p. 9).
The 19th century was a period of intertribal conflict as much as between Indians and whites, especially as settlement drove eastern tribes westward onto other tribes’ lands. Furthermore, almost every tribe was split into two groups, one wishing to accommodate whites and one opposed to them (p. 16).
