Black Hawk (1767 – October 3, 1838) was a leader and warrior of the Sauk American Indian tribe in what is now the United States. Although he had inherited an important historic medicine bundle, he was not one of the Sauk's hereditary civil chiefs. His status came from leading war parties as a young man, and from his leadership of a band of Sauks during the Black Hawk War of 1832. During the War of 1812, Black Hawk fought on the side of the British. Later he led a band of Sauk and Fox warriors, known as the British Band, against European-American settlers in Illinois and present-day Wisconsin in the 1832 Black Hawk War. After the war, he was captured and taken to the eastern U.S., where he and other leaders toured several cities. Black Hawk died in 1838 in what is now southeastern Iowa. He left behind an enduring legacy through many eponyms and other tributes.
