Meanwhile, the Miami lands in Indiana were being lost to treaties, debts, and taxes. Treaties signed in 1826, 1828, and 1838 took portions of their reserves until the final treaty signed at the Forks of the Wabash in 1840 ceded the last 177,000 acres of the big reserve for $550,000 – $325,000 of which was used to pay debts. Except for Meshingomesia’s band – whose chief owned the land in fee simple – the Miami agreed to remove to Kansas within five years. On October 7, 1846, 555 Miami left Indiana by canal boat and were settled at the approach of winter along the Marais des Cygnes River in eastern Kansas on land adjoining the Piankashaw, Wea, and Peoria. The 500 to 1,500 Miami who remained in Indiana were heavily intermarried with whites so estimates of their number are difficult. The lands of Meshingomesia’s band were divided among the 300 survivors in 1872 and soon lost to land speculators and tax sales. In 1897 the assistant U.S. attorney general terminated the tribal status of the Indian Miami. No explanation for this action was ever given.
Throughout the 1840s, approximately 1,000 Miami lived in eastern Kansas. By 1854 the Wea and Piankashaw had decided to form a single tribe with the 300 Kaskaskia and Peoria which were all that remained of the once-numerous Illinois Confederation. The United States, however, was anxious to open Kansas for settlement to facilitate construction of a transcontinental railroad and wanted to purchase native lands. In June 1854 at Washington, D.C., the Miami and combined Peoria-Miami tribe ceded more than 500,000 acres in exchange for 200 acre individual allotments plus ten sections to be held in common, but no offer of citizenship was made in return for the acceptance of allotment. White settlers flooded into Kansas to determine the question of black slavery with violence, and native lands were fair game for the heavily-armed squatters. The outbreak of the Civil War brought thousands of native refugees to Kansas fleeing the violence in Oklahoma. In the midst of this, Kansas became a state in 1862, and the following year, its legislature asked the federal government to remove Native Americans.
Action on this request had to await the end of the war, but in an omnibus treaty signed in 1867, the Miami and the United Peoria and Miami Tribe (merged group of Peoria, Wea, and Piankashaw), together with the Ottawa, Quapaw, Seneca, Seneca, Wyandot, Delaware and Shawnee, ceded their last Kansas lands and agreed to remove to Oklahoma. They purchased 6,000 acres in the northeast corner of the state in what is now Ottawa County. No sooner had the Miami left Kansas, than white squatters moved into their old lands before they could be auctioned. Army troops had to be used in 1870 to remove them. The Peoria and Miami lands in Oklahoma were allotted in 1893, and the excess given to Ottawa County in 1907. By the 1930s both the Oklahoma and Indiana Miami were completely landless, although the Oklahoma tribe has since acquired 160 acres which are held in trust. The United Peoria were terminated in 1950 but restored to federal status in 1972. The Miami Tribe of Oklahoma never lost its federal recognition, something the Indiana Miami have never been able to regain.
