When white settlers began streaming into the Illinois country after the War of 1812, the Sauks and Foxes fled across the Mississippi. A subordinate chief, Black Hawk, refused to retreat. He created an alliance with the Winnebagos, Pattawotamies, and Kickapoos, and declared war against the new settlements. A band of Winnebagos, who accepted a white soldier chief's bribe of twenty horses and a hundred dollars, betrayed Black Hawk, and he was captured in 1832. He was taken East for imprisonment and display to the curious. After he died in 1838, the governor of the recently created Iowa Territory obtained Black Hawk's skeleton and kept it on view in his office.
Interestingly, from Wikipedia:
In 1986, while going through the team's records, someone discovered the team's original NHL contract, and found that the name "Blackhawks" was printed as a compound word as opposed to two separate words ("Black Hawks") which was the way most sources had been printing it for 60 years and as the team had always officially listed it. The name officially became "Chicago Blackhawks" from that point on.
