Most of the first non-Native American settlers came fromEffingham County in 1786.[3] On February 11, 1796, Jackson County was split off from part ofFranklin County,Georgia. The new county was named in honor of Revolutionary War Lieutenant Colonel, Congressman, Senator and GovernorJames Jackson.[4] The county originally covered an area of approximately 1,800 square miles (4,662.0 km2), withClarksboro as its first county seat.
In 1801, theGeorgia General Assembly granted 40,000 acres (160 km2) of land in Jackson County for a state college. Franklin College (nowUniversity of Georgia) began classes the same year, and the city ofAthens was developed around the school. Also the same year, a new county was developed around the new college town, and Jackson lost territory to the newClarke. The county seat was moved to an old Indian village called Thomocoggan, a location with ample water supply from Curry Creek and four large springs. In 1804, the city was renamedJefferson, afterThomas Jefferson.
The first county courthouse, a log and wooden frame building with an attached jail, was built on south side of the public square; a second, larger, two-story brick courthouse with a separate jailhouse was built in 1817. In 1880, a third was built on a hill north of the square. This courthouse was the oldest continuously operating courthouse in the United States until 2004, when the current courthouse was constructed north of Jefferson.
According to theU.S. Census Bureau, the county has a total area of 343 square miles (890 km2), of which 340 square miles (880 km2) is land and 3.4 square miles (8.8 km2) (1.0%) is water.[6]
