The Miami (Miami-Illinois: Myaamiaki) are a Native American nation originally speaking one of the Algonquian languages. Among the peoples known as the Great Lakes tribes, they occupied territory that is now identified as north-central Indiana, southwest Michigan, and western Ohio. The Miami were historically made up of several prominent subgroups, including the Piankeshaw, Wea, Pepikokia, Kilatika, Mengakonkia, and Atchakangouen. In modern times, Miami is used more specifically to refer to the Atchakangouen. By 1846, most of the Miami had been forcefully displaced to Indian Territory (initially to what is now Kansas, and later to what is now part of Oklahoma). The Miami Tribe of Oklahoma are the federally recognized tribe of Miami Indians in the United States. The Miami Nation of Indiana, a nonprofit organization of descendants of Miamis who were exempted from removal, have unsuccessfully sought separate recognition.
The name Miami derives from Myaamia (plural Myaamiaki), the tribe's autonym (name for themselves) in their Algonquian language of Miami-Illinois. This appears to have been derived from an older term meaning "downstream people." Some scholars contended the Miami called themselves the Twightwee (also spelled Twatwa), supposedly an onomatopoeic reference to their sacred bird, the sandhill crane. Recent studies have shown that Twightwee derives from the Delaware language exonym for the Miamis, tuwéhtuwe, a name of unknown etymology. Some Miami have stated that this was only a name used by other tribes for the Miami, and not their autonym. They also called themselves Mihtohseeniaki (the people). The Miami continue to use this autonym today.
Prehistory of Ohio
Early Miami people are considered to belong to the Fischer Tradition of Mississippian culture. Mississippian societies were characterized by maize-based agriculture, chiefdom-level social organization, extensive regional trade networks, hierarchical settlement patterns, and other factors. The historical Miami engaged in hunting, as did other Mississippian peoples.
