The Black Hawk State Historic Site, in Rock Island, Illinois, is adjacent to the historic site of the village of Saukenuk, the home of a band of Native Americans of the Sauk nation. It includes the John Hauberg Museum of Native American Life. The state park is located on a bluff overlooking the Rock River in western Illinois. It is most famous for being the birthplace of the Sauk warrior Black Hawk. The disputed cession of this area to the U.S. Government was the catalyst for the Black Hawk War. Under the Sauk The Sauk nation occupied this site as their principal village, called "Saukenuk". It was a well-drained area, suitable for growing corn. The Sauk had arrived by 1750, probably after the Fox Wars (1712-1733). When the explorer Jonathan Carver reached Saukenuk in 1766, he called it "the largest and best built Indian town" he had ever seen, "more like a civilized town than the abode of savages." The Sauk successfully farmed the area during part of the year and spent the winters in camps down and across the Mississippi collecting fur-bearing animals. Sauk hunters skinned their catches and sold the peltry to fur traders from the Great Lakes. From 1763 on, these traders were mostly British, and from the 1780s on, most of them were employees or contractors of the Canada-based North West Company. In the spring, the Sauk gathered in sugar camps for maple sugaring before returning to the village (left empty since the fall) to plant crops and bury their dead. The Sauk developed military and economic ties with British North America. Due to these ties, the Sauk expected British military assistance. Some of the Sauk traveled every year to British forts on far-away Lake Superior and near Detroit for trading and gift-giving. A disputed 1804 St. Louis Treaty between Quashquame and William Henry Harrison led to the transfer of Illinois lands to the U.S. Government, including Saukenuk. The Sauk did not consider this treaty valid, and they continued to live at the village. When Thomas Forsyth arrived in Saukenuk in 1817, he described it as the most populous Indian village he had ever seen. By 1826, an estimated 4,800 Sauk lived in and around Saukenuk. Others who passed through, such as William H. Keating, noted that the village was not limited to the Sauk. Keating estimated only about 20% of the warriors that the Sauk
