About Franklin County, Ohio
Franklin County is Ohio’s most populous county. The county seat and largest city is Columbus, the state capital and largest city in Ohio which takes up nearly half of the county’s total area.
Named for Benjamin Franklin, Franklin County was established just after Ohio became a state in 1803. Columbus became the capital in 1816 when it was chosen for its central location and major river access. Interestingly, Columbus was only laid out by surveyors in 1812, just four years before it became the capital. It was designed from the beginning as the capital for the state and its population grew from 700 people in 1815 to 4,000 in 1834 when it was large enough for the status of “city.”
