Who would have thought that Prairie du Chien—then part of the Michigan Territory—would be the site of multiple international treaties?
Another addition to the Fort Crawford Museum is the long-anticipated Treaties of Prairie du Chien Exhibit.
These treaties were signed in Prairie du Chien between the United States and Native nations—the Sioux, Fox, Sac, Winnebago, Potawatomi, Menominee, Ioway, and Ottawa—in 1825, 1829, and 1830.
These agreements played a significant role in shaping federal Indian policy during the era of the Indian Removal Act of 1830. The proceedings were documented by artist James Otto Lewis, whose Aboriginal Portfolio features hand-colored lithographs of Native leaders who participated in the councils.
The new exhibit explores the historical context and impact of these treaties and includes original lithographs by Lewis.
Come see these depictions of multinational meetings when the museums of the Prairie du Chien Historical Society open on May 16, marking the Society’s 30th year.
Hours: 10:00 a.m.–4:00 p.m., Wednesday through Monday (closed Tuesdays).
