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

. 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,

This land was part of the United States Military District surveyed by Israel Ludlow in 1797 and divided into townships square. Before the state legislature's decision in 1812, Columbus did not exist. The city was originally designed as the state's new capital, preparing itself for its role in Ohio's political, economic, and social life. In the years between the 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.

Politics

For most of the 20th century, Franklin County shared the heavy Republican bent of the rest of central Ohio, and was one of the more conservative urban counties in the nation. From 1896 to 1992, it went Republican all but five times, the last three of which were national Democratic landslides that saw the Democratic candidate win over 400 electoral votes. However, it has gone Democratic in every election since 1996, reflecting the Democratic trend in most other urban counties nationwide. Columbus and most of its northern and western suburbs lean Democratic, while the more blue-collar southern section of the county leans Republican. From 1996 to 2004, Democratic nominees carried the county by single digit margins, but it swung significantly in favor of
