Black Hawk, born Ma-ka-tai-me-she-kia-kiak (1767 – October 3, 1838), was a Sauk leader and warrior who lived in what is now the Midwestern United States. Although he had inherited an important historic sacred bundle from his father, he was not a hereditary civil chief. Black Hawk earned his status as a war chief or captain by his actions: leading raiding and war parties as a young man and then a band of Sauk warriors during the Black Hawk War of 1832.

During the War of 1812, Black Hawk fought on the side of the British against the US in the hope of pushing white American settlers away from Sauk territory. Later, he led a band of Sauk and Fox warriors, known as the British Band, against white settlers in Illinois and present-day Wisconsin during the 1832 Black Hawk War. After the war, he was captured by US forces and taken to the Eastern US, where he and other war leaders were taken on a tour of several cities.

Shortly before being released from custody, Black Hawk told his story to an interpreter. Aided also by a newspaper reporter, he published Autobiography of Ma-Ka-Tai-Me-She-Kia-Kiak, or Black Hawk, Embracing the Traditions of his Nation... in 1833 in Cincinnati, Ohio. The first Native American autobiography to be published in the US, his book became an immediate bestseller and has gone through several editions. Black Hawk died in 1838, at age 70 or 71, in what is now southeastern Iowa. He has been honored by an enduring legacy: his book, many eponyms, and other tributes.
