The Ho-Chunk Nation is a federally recognized tribe of the Ho-Chunk with traditional territory across five states in the United States: Wisconsin, Illinois, Iowa, Minnesota, and Missouri. The other federally recognized tribe of Ho-Chunk people is the Winnebago Tribe of Nebraska. The tribe separated when its members were forcibly relocated first to an eastern part of Iowa known as the Neutral Ground, then to Minnesota, South Dakota and later to the current reservation in Nebraska.
