History
Frankfort was established in the early nineteenth century as part of the broader settlement of Ross County, one of the oldest organized counties in Ohio and a region with deep ties to early American westward expansion. The village grew as an agricultural and trade community, benefiting from its location along key roadways that connected early Ohio settlements. Ross County as a whole played a significant role in Ohio's early statehood era, and communities like Frankfort reflect the enduring legacy of pioneer settlement in the Paint Creek Valley.
