Peoria people in the context of Native Americans of the United States

Miami–Illinois or Wabash (endonym: myaamia, [mjɑːmia]) is an Indigenous Algonquian language that is spoken in the United States, historically in Illinois, Missouri, Indiana, western Ohio and adjacent areas along the Mississippi River by the Miami and Wea as well as the tribes of the Illinois Confederation, including the Kaskaskia, Peoria, Tamaroa, Cahokia, and possibly Mitchigamea. Although the last native speaker died in 1989, there has been an effort by the Myaamia (Miami) Nation of Oklahoma and the Miami Nation of Indians of the State of Indiana (a nonprofit organization) to revive the language and preserve their native heritage by teaching it to young and old members. As of 2016, it is estimated that around 500 members of the tribe use the language on a regular basis.

Peoria (/piˈɔːriə/ pee-OR-ee-ə) is a city in Peoria County, Illinois, United States, and its county seat. Located on the Illinois River, the city had a population of 113,150 as of the 2020 census, making it the eighth-most populous city in Illinois. It is the principal city of the Peoria metropolitan area in Central Illinois, consisting of Fulton, Marshall, Peoria, Stark, Tazewell, and Woodford counties and home to 402,391 people in 2020.

Established in 1691 by the French explorer Henri de Tonti, Peoria is the oldest permanent European settlement in Illinois, according to the Illinois State Archaeological Survey. Originally known as Fort Clark, it received its current name when the County of Peoria was organized in 1825. The city was named after the Peoria people, a member of the Illinois Confederation. On October 16, 1854, Abraham Lincoln made his Peoria speech against the Kansas–Nebraska Act. Prior to prohibition, Peoria was the center of the whiskey industry in the United States. More than 12 distilleries operated in Peoria by the end of the 19th century, more than any other city in the U.S.

The Wea (Miami–Illinois: Waayaahtanwa) were a Miami–Illinois-speaking Native American tribe originally located in western Indiana. Historically, they were described as being either closely related to the Miami tribe or a sub-tribe of Miami.

Today, the descendants of the Wea, along with the Kaskaskia, Piankeshaw, and Peoria, are enrolled in the Peoria Tribe of Indians of Oklahoma, a federally recognized tribe in Oklahoma.
