A Siouan Tribe, native to the Great Plains where the Algonquinans were pushed by westward expansion and therefore their long-term enemies at the time of Removal.

In Oklahoma Territory, about 90 Iowa families were settled between the Cimarron River and Deep Fork, between the Unassigned Lands and the Sac & Fox.  This is in the easternmost part of present-day Logan and Oklahoma Counties, the northwestern part of Lincoln County, and the southwestern part of Payne Co. 

After 109 individual allotments were carved out of these lands, the rest was opened by run on September 22, 1891 along with the Sac & Fox, Pottawatomie, and Shawnee Lands.  By 1900, no Iowa families remained in Logan or Oklahoma Counties.  Although I found eleven Iowa families enumerated in Lincoln County and three in Payne County, only one Head of Household appears to be living in the area of his allotment.
