Miami people
Richardville and other Miami leaders were criticized for personally benefitting from their roles as tribal chiefs and treaty negotiators. However, their efforts successfully delayed for decades the removal of the Miami people to federal lands west of the Mississippi River and gained additional time to negotiate concessions and obtain the best prices available for Miami lands. Treaty provisions that they negotiated also allowed about half of the Miami people, including 43 members of Richardville's family, to remain in Indiana after the remainder of the Miamis moved west in 1846. Richardville also provided displaced Miamis in Indiana with a place to stay on the few hundred remaining acres of his property. Those who remained in Indiana were among the original 148 members of the Miami Nation of Indiana, which began on October 6, 1846. Over the years, some of Richardville's family members migrated to what became the present-day states of Kansas and Oklahoma, but many more of his descendants remained in Indiana.
