Winnebago War - Background

Background

Following the War of 1812, the United States pursued a policy of trying to prevent wars among Native Americans in the Upper Mississippi River region. This was not strictly for humanitarian reasons: intertribal warfare made it more difficult for the United States to acquire Indian land and move the tribes to the West, a policy known as Indian removal, which had become the primary goal by the late 1820s. On August 19, 1825, U.S. officials finalized a multi-tribal treaty at Prairie du Chien, which defined the boundaries of the region's tribes.

By that time, however, white Americans had begun to trespass on Ho-Chunk (or Winnebago) lands in large numbers, drawn by the promise of easy lead mining along the Fever (later Galena) River. Native Americans had mined this region for thousands of years, and exporting lead had become an important part of the Ho-Chunk economy. Ho-Chunks tried to drive away the trespassers, but they often suffered abuse at the hands of aggressive miners. Some U.S. officials, concerned that Ho-Chunk mining would delay what they saw as the inevitable American possession of the mining region, worked "to dissuade the Indians from their mining plans".
