🏛️ Where Did the Name East Peoria Come From?
At first glance, East Peoria seems like one of the easiest community names in Central Illinois to explain. It's simply located east of Peoria, right?
Well, not exactly.
The area that would become East Peoria was first settled in the early 1800s and was originally known as Fondulac, a name given by French settlers. "Fond du Lac" is French for "bottom of the lake" or "end of the lake," referring to its location near the lower end of what is now known as Lake Peoria.
Long before European settlers arrived, Native American tribes, including members of the Illiniwek Confederation, lived throughout the Illinois River Valley. The river provided transportation, food, and trade opportunities for centuries before Illinois became a state in 1818.
Throughout the 1800s, Fondulac developed as an important transportation and commercial center. Its location across the river from Peoria made it a natural hub for trade, river traffic, and later railroad activity. Ferries carried passengers and goods across the Illinois River years before bridges connected the two communities.
As Peoria continued to grow, many people increasingly identified the community on the east side of the river by its relationship to its larger neighbor. In 1884, the Village of East Peoria was officially incorporated, replacing the name Fondulac for the growing community.
The city continued to expand during the late 1800s and early 1900s, eventually becoming home to major industries, including Caterpillar, which would play a significant role in shaping the local economy for generations.
Having lived in East Peoria twice, I've always appreciated the community's unique identity. While many people think of it as simply being across the river from Peoria, East Peoria has a rich history all its own. I also learned to drive in Fondulac Heights, so this community has always held a special place in my memories.
Today, East Peoria is one of the most vibrant communities in Central Illinois, known for its riverfront development, businesses, parks, and beautiful views of the Illinois River Valley.
