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 Iowas were settled between the Cimarron River and Deep Fork, between the Unassigned Lands and the Sac & Fox. This is in the eastern part of present-day Logan and Oklahoma Counties and the western part of Lincoln County.
After 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.
