Seneca County, Ohio has a rich and varied history that dates back thousands of years. The area was originally inhabited by various Native American tribes, including the Wyandot and Shawnee, who used the land for hunting and fishing. In the late 18th century, European settlers began to arrive in the region, with the first permanent white settlement established in present-day Seneca County in 1817. The county was officially created in 1820 and named after the powerful Seneca Native American tribe.

During the 19th century, Seneca County experienced significant growth and development. The construction of the Miami and Erie Canal in the 1830s boosted the local economy by providing a reliable transportation route for goods and people. This led to the establishment of several canal towns, including Tiffin, the county seat. Tiffin quickly grew into a thriving community, home to mills, schools, churches, and businesses.

Seneca County played a role in the Underground Railroad, a network of secret routes and safe houses used by enslaved African Americans to escape to freedom. Abolitionists in the area provided support and shelter for escaped slaves, helping them on their journey to Canada. The region also had a strong German immigrant presence, with many settling in Seneca County and establishing successful businesses and farms.

In the 20th century, Seneca County continued to evolve and adapt. The construction of highways such as U.S. Route 224 and State Route 53 improved connectivity and transportation, further promoting economic development.
