It is surrounded by the village of Germantown. The land that became Germantown was originally inhabited by Native Americans, including the Potawatomi tribe. The Potawatomi surrendered the land that became Germantown the United States Federal Government in 1833 through the 1833 Treaty of Chicago, which required them to leave Wisconsin by 1838. While many Native people moved west of the Mississippi River to Kansas, some chose to remain, and were referred to as "strolling Potawatomi" in contemporary documents because many of them were migrants who subsisted by squatting on their ancestral lands, which were now owned by white settlers. Eventually the Native Americans who evaded forced removal gathered in northern Wisconsin, where they formed the Forest County Potawatomi Community.
