On March 30, 1803, the Ohio government authorized the creation of Franklin County. The county originally was part of Ross County. Residents named the county in honor of Benjamin Franklin.  In 1816, Franklin County's Columbus became Ohio's state capital. Surveyors laid out the city in 1812, and officials incorporated it in 1816. Columbus was not Ohio's original capital, but the state legislature chose to move the state government there after its location for a short time at Chillicothe and at Zanesville. Columbus was chosen as the site for the new capital because of its central location within the state and access by way of major transportation routes (primarily rivers) at that time. The legislature chose it as Ohio's capital over a number of other competitors, including Franklinton, Dublin, Worthington, and Delaware.
On May 5, 1802 a group of prospective settlers founded the Scioto Company at the home of Rev. Eber B. Clark in Granby, Connecticut for the purpose of forming a settlement between the Muskingum River and Great Miami River in the Ohio Country. James Kilbourne was elected president and Josiah Topping secretary (McCormick 1998:7). On August 30, 1802 James Kilbourne and Nathaniel Little arrived at Colonel Thomas Worthington's home in Chillicothe, Ohio. They tentatively reserved land along the Scioto River on the Pickaway Plains for their new settlement (McCormick 1998:17).
On October 5, 1802, the Scioto Company met in Granby, Connecticut and decided not to purchase the lands along the Scioto River on the Pickaway Plains, but rather to buy land 30 miles (48 km) farther north from Dr. Jonas Stanbery and his partner, an American Revolutionary War general, Jonathan Dayton. Sixteen thousand acres (65 km²) were purchased along the Whetstone River (now known as the Olentangy River) at $1.50 per acre (McCormick 1998:19-27). This land was part of the United States Military District surveyed by Israel Ludlow in 1797 and divided into townships 5 miles (8.0 km) square. 
Before the state legislature's decision in 1812, Columbus did not exist. The city was designed from the first as the state's capital, preparing itself for its role in Ohio's political, economic, and social life. In the years between first ground-breaking and the actual movement of the capital in 1816, Columbus and Franklin County grew significantly. By 1813, workers had built a penitentiary, and by the following year, residents had established the first church, school, and newspaper in Columbus. Workers completed the Ohio Statehouse in 1861. Columbus and Franklin County grew quickly in population, with the city having 700 people by 1815. Columbus officially became the county seat in 1824. By 1834, the population of Columbus was 4,000 people, officially elevating it to "city" status.
According to the U.S. Census Bureau, the county has a total area of 544 square miles (1,410 km2), of which 532 square miles (1,380 km2) is land and 11 square miles (28 km2) (2.1%) is water.  The county is located in the Till Plains and the Appalachian Plateau land regions.
The county is drained by the Olentangy River and the Scioto River. Major creeks in the county include Big Darby Creek, Big Walnut Creek, and Alum Creek. There are two large reservoirs in the county, Hoover Reservoir and Griggs Reservoir.
