Illinois Indians,
A family of the Algonquian nation that comprised several clans—Peorias, Moingwenas, Kaskaskias, Tamnaroas, and Cahokias. At a very early period they drove a Dakota tribe, whom they called the Arkansas, to the country on the southern Mississippi. These were the Quapaws. In 1640 they almost exterminated the Winnebagoes; and soon afterwards they waged war with the Iroquois and Sioux. Their domain was between Lakes Michigan and Superior and the Mississippi River. Marquette found some of them (the Peorias and Moingwenas) near Des Moines, west of the Mississippi, in 1672; also the Peorias and Kaskaskias on the Illinois River. The Tamaroas and Cahokias were on the Mississippi. The Jesuits found the chief Illinois town consisting of 8,000 people, in nearly 400 large cabins, covered with water-proof mats, with, generally, four fires to a cabin. In 1679 they were badly defeated by the Iroquois, losing about 1,300, of whom 900 were prisoners: and they retaliated by assisting the French, under De la Barre and De Nonville, against the Five Nations. The Illinois were converted to Christianity by Father Marquette and other missionaries, and in 1700 Chicago, their great chief, visited France, where he was much caressed. His son, of the same name, maintained great influence in the tribe until his death, in 1754. When Detroit was besieged by the Foxes, in 1712, the Illinois went to its relief, and in the war that followed they suffered severely. Some of them were with the French at Fort Duquesne; but they refused to join Pontiac in his [5] conspiracy. With the Miamis, they favored the English in the war of the Revolution, and joined in the treaty at Greenville in 1795. By the provision of treaties they ceded their lands, and a greater portion of them went to a country west of the Mississippi, within the present limits of Kansas, where they remained until 1867, when they were removed to a reservation of 72,000 acres southwest of the Quapaws. In 1872 the whole Illinois nation had dwindled to forty souls. This tribe, combined with the Weas and Piankeshaws, numbered only 160 in all.
