Black Hawk (1767-1838), also called Makataimeshekiakiak, was the leader of
the Thunder clan of the Sauk Indians in Illinois.  In an effort to halt
the settlers' westward expansion, he sided with the British against the
Americans in the War of 1812.  When he led his tribe back to settle their
disputed homeland in Illinois, two Sauks were shot by a body of Illinois
volunteers.  This led Black Hawk's War in 1832, a guerrilla conflict waged
against the Americans.  Finally, left with only a few warriors, Black
Hawk, dressed in white deerskin, turned himself in.  Though a prisoner, he
was immensely popular, and in 1833 was presented to President Andrew
Jackson.  Jackson allegedly felt so threatened by Black Hawk's popularity
that he released the chief and sent back to the West.
