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.
Hancock County, Ohio is a county located in the northwestern part of the state. Its history dates back to the early 1800s when it was originally inhabited by Native American tribes, including the Shawnee and Wyandot. European settlement began in the early 1820s, with pioneers from Pennsylvania and Virginia establishing towns such as Findlay, the county seat.

The county's development was greatly influenced by the discovery of oil and natural gas in the late 1800s. This led to an influx of industries and population growth, as people flocked to the area for employment opportunities. Findlay became known as the "Oil Capital of the World" due to its significant oil production, and this industry played a pivotal role in shaping the county's economic and cultural landscape.

Over the years, Hancock County has experienced periods of prosperity and challenges. During World War II, the county's manufacturing sector boomed as it supported the war effort. After the war, the county continued to diversify its economy, with manufacturing, agriculture, and healthcare becoming prominent industries.

It is home to the University of Findlay, which was established in 1882 and has since become an integral part of the county's educational system.
