The story

How Peoria City Township came to be

From Wikipedia’s history of Peoria City Township.

Read it all →

Peoria was the earliest permanent European settlement in what is now Illinois; French explorers first established a presence along the Illinois River in the late 17th century, with the community later evolving into the modern city. The lands that eventually would become Peoria were first settled by Europeans in 1680, when French explorers René-Robert Cavelier, Sieur de La Salle and Henri de Tonti constructed Fort Crevecoeur. This fort burned to the ground, and in 1813, Fort Clark, Illinois was built. When the County of Peoria was organized in 1825, Fort Clark was officially named Peoria.
