Chief Shabona

Chief Shabbona
Shabbona, a Potawatomi chief, signed numerous treaties for Native American tribes. Settling in De Kalb County, Illinois, after the War of 1812, Shabbona lived there for decades. Upon his return from visiting the Potawatomi in Kansas sometime after 1848, he found that his land had been declared abandoned. He lived with his family in a cabin on the Illinois River until his death in 1859.
