White settlement began around 1800, and the county was formally organized in 1807 and named forBenjamin Franklin.[3][4] During the next several decades, the size of the county was reduced several times by reorganizations which created the neighboring counties ofCoffee County,Moore County, andGrundy County. One of the most notable early settlers was frontiersmanDavy Crockett, who came about 1812 but is not thought to have remained long.[3]
TheUniversity of the South, founded by the Episcopal Church, was organized just before theCivil War. It began full operations shortly after hostilities ceased. It encompasses a full university and theological seminary. The University of Tennessee Space Institute is also located in the county.
The area became stronglysecessionist before the war. Franklin County formally threatened tosecede from Tennessee and joinAlabama if Tennessee did not leave the union, which the state did when forced to take sides by Abraham Lincoln.[3] This contrasted sharply with the situation in not distantWinston County, Alabama, which was largely pro-Union and provided more volunteers for the Union than the Confederacy.
During 1863, theArmy of Tennessee retreated through the county, leaving it more or less under Union control for the rest of the war, although some guerrilla warfare still took place.Isham G. Harris, the Confederate governor of Tennessee, was from Franklin County. After having his political rights restored after the war, he was chosen to represent the state in theUnited States Senate.
During thetemperance (anti-liquor) agitations of the late 19th century, residents discovered that by a quirk of state law, liquor could be sold only inincorporated towns. As a result, all of the county's towns abolished their charters in order to prohibit the sale of alcohol.[3]
In the 20th century, Franklin County benefited from the flood control and power generation activities of theTennessee Valley Authority (TVA), built by the PresidentFranklin D. Roosevelt administration during theGreat Depression. The TVA helped bring new industry to the area. It also created opportunities for water recreation by making new lakes, but at the same time also displaced many county residents from their soon to be submerged homes. The establishment of the federalArnold Engineering Development Center, which is partly within the county, helped spur economic growth and technical development. Theinterstate highway system barely touched the county, but it did provide valuable access onInterstate 24 to nearbyChattanooga.
Two notable figures who were born in the county early in the twentieth century were singer/entertainerDinah Shore and entrepreneur/philanthropistJohn Templeton. He later became a British subject and was awarded aknighthood.
During the last decades of the 19th and the first of the 20th, Tennessee, like other southern states, passed laws and constitutional amendments establishingJim Crow:racial segregation in public facilities, restrictions of voting for blacks, and similar measures. There were few violent disturbances in Franklin County compared to many other localities, but it was not until a decade after the historicBrown v. Board of Education court decision that the county's schools weredesegregated in 1964 whena lawsuit was won in Sewanee, Tennessee.
Considerable industrial growth occurred in the county in the last decades of the 20th century, including the construction of a large automobile engine plant by theNissan corporation inDecherd. An emphasis on tourism also developed, based on Civil War history and local scenic attractions such as thedogwood forests, for which an annual festival is held.

Franklin is one of Tennessee's southern tier of counties and abuts theAlabama border. It has a varied geography, extending from the southeast corner of theNashville Basin over theHighland Rim and up onto theCumberland Plateau, for a difference in elevation of about 1,300 feet (400 m). The county is well watered and forested, and except for the steeper areas of the plateau is well suited for agriculture, having a long growing season and mild winters.
Lost Cove Cave, located near Sherwood, is in the Carter State Natural Area. One of its entrances is known as the Buggytop Cave Entrance and another entrance is known as the Peter Cave Entrance.
