In 1832, facing white expansion, the Sauk warrior Black Hawk attempted to forge a pan-Indian alliance to preserve the homelands of the confederated Sauk and Fox tribes on the eastern bank of the Mississippi. Here, Patrick J. Jung re-examines the causes, course, and consequences of the ensuing war with the United States, a conflict that decimated Black Hawk’s band. Correcting mistakes that plagued previous histories, and drawing on recent ethnohistorical interpretations, Jung shows that the outcome can be understood only by discussing the complexity of intertribal rivalry, military ineptitude, and racial dynamics.
