The Ohio River Valley was home to several Native American cultures before European settlement, including the Adena and Hopewell cultures. These cultures left behind many burial mounds and other archaeological sites that are now protected and preserved by the state of Ohio.

Allen County, OH has a rich and diverse history that spans over two centuries. The area was originally inhabited by Native American tribes, including the Shawnee and Delaware, before European settlers arrived in the late 1700s. The first permanent settlement in Allen County was established in 1815 along the Auglaize River, and the county itself was officially created in 1820.

Manufacturing companies, including the Lima Locomotive Works, gained prominence and provided employment opportunities for many residents.
