Iowa ('sleepy ones'). One of the southwestern Siouan tribes included by J. O. Dorsey with the Oto and Missouri in his Chiwere group. Traditional and linguistic evidence proves that the Iowa sprang from the Winnebago stern, which appears to have been the mother stock of some other of the southwestern Siouan tribes; but the closest affinity of the Iowa is with the Oto and Missouri, the difference in language being merely dialectic.
Iowa chiefs informed Dorsey in 1883 that their people and the Oto, Missouri, Omaha, anti Ponca "once formed part of the Winnebago nation." According to the traditions of these tribes, at an early period they came with the Winnebago from their priscan home north of the great lakes, but that the Winnebago stopped on the shore of a great lake (Lake Michigan), attracted by the abundant fish, while the others continued southwestward to the Mississippi. Here another band, the Iowa, separated from the main group, "and received the name of Pahoja, or Gray Snow, which they still retain, but are known to the white people by the name of Ioway, or Aiaouez. The first stopping place of the Iowa, after parting from the Winnebago, as noted in the tradition, appears to have been on Rock river, Ill., near its junction with the Mississippi. Another tradition places them farther north.
In 1848 a map was drawn by a member of the tribe showing their movements from the mouth of Rock river to the place where they were then living. According to this their first move was to the banks of Des Moines river, some distance above its mouth; the second was to the vicinity of the pipestone quarry in southwest Minnesota, although on the map it was placed erroneously high up on the Missouri; thence they descended to the mouth of Platte river, and later moved successively to the headwaters of Little Platte river, Mo.; to the west bank of the Mississippi, slightly above the mouth of Des Moines river, a short distance farther up on the same side of the Mississippi; again southwestwardly, stopping on Salt river, thence going to its extreme headwaters; to the upper part of Chariton river; to Grand river; thence to Missouri river, opposite Ft Leavenworth, where they lived at the time the map was drawn. These successive movements, which are of comparatively recent date, are generally accepted as substantially correct. The Sioux have a tradition (Williamson in Minn. Hist. Coll., 1, 296) that when their ancestors first came to the falls of St Anthony, the Iowa occupied the country about the mouth of Minnesota river, while the Cheyenne dwelt higher up on the same stream. The Iowa appear to have been in the vicinity of the mouth of Blue Earth river, Minn., just before the arrival there of Le Sueur in 1701 for the purpose of erecting his fort. His messengers, sent to invite them to settle in the vicinity of the fort because they were good farmers, found that they had recently removed toward Missouri river, near the Maha (Omaha), who dwelt in that region. The Sioux informed Le Sueur that Blue Earth river belonged to the Scioux of the West (Dakota), the Ayavois (Iowas), and Otoctatas (Oto), who lived a little farther off. Father Marest (La Harpe, Jour., 39, 1851) says that the Iowa were about this (late associated with the Sioux in their war against the Sauk. This does not accord with the general tradition that the Dakota were always enemies of the Iowa, nevertheless the name Nadoessi Maseouteins seems to have been applied to the Iowa by the early missionaries because of their relations for a time with the Sioux. Pere Andre thus designated them in 1676, when they were living 200 leagues west of Green Bay, Wis. Perrot (Mem., 63, 1864) apparently located them in the vicinity of the Pawnee, on the plains, in 1685. Father Zenobius (1680) placed the Anthoutantas (Oto) and Nadouessious Maskoutens (Iowa) about 130 leagues from the Illinois, in 3 great villages built near a river which empties into the river Colbert (Mississippi) on the west side, above the Illinois, almost opposite the mouth of the Wisconsin. He appears to locate a part of the Ainoves (perhaps intended for Aioues), on the west side of Milwaukee river, in Wisconsin. On Marquette's map (1674-79) the Pahoutet (Iowa), the Otontanta (Oto), and Maha (Omaha) are placed on Missouri river, evidently by mere guess. La Salle knew of the Oto and the Iowa, and in his letter in regard to Hennepin, Aug. 22, 1682, mentions them under the names Otoutanta and Aiounouea, but his statement that Accault, one of his company, knew the languages of these tribes is doubtful. It is probable that in 1700, when Le Sueur furnished them with their first firearms, the Iowa resided on the extreme headwaters of Des Moines river, but it appears from this explorer's journal that they and the Oto removed and "established themselves toward the Missouri river, near the Maha".
