# Knox County, Tennessee

Knox County is a county located in the U.S. state of Tennessee. As of the 2020 census, the population was 478,971, making it the third-most populous county in Tennessee. Its county seat is Knoxville, which is the third-most populous city in Tennessee. Knox County is included in the Knoxville metropolitan area. The county is located at the geographical center of the Great Valley of East Tennessee. Near the heart of the county is the origin of the Tennessee River, at the confluence of the Holston and French Broad rivers.

## History

Knox County was created after the American Revolutionary War on June 11, 1792, by Governor William Blount from parts of Greene and Hawkins counties. It was one of the few counties created when this area was still known as the Southwest Territory. It is one of nine United States counties named for American Revolutionary War general Henry Knox, who was appointed as the first United States Secretary of War. As population increased, parts of Knox County were taken out to form Blount (1795), Anderson (1801), Roane (1801), and Union (1850) counties.
In 1783, James White and Francis Alexander Ramsey led an expedition to explore the Upper Tennessee Valley, now within the boundaries of Knox County. White moved to what is now the Riverdale community in the eastern part of the county in 1785, and the following year constructed a fort a few miles to the west. A community developed around the fortified trading post, ultimately becoming the city of Knoxville. Governor Blount designated the fort as the capital of the Southwest Territory in 1790, and gave the new town the name "Knoxville" after his superior, Henry Knox.
Blount began construction of his house, Blount Mansion, in the early 1790s. This is one of a number of late eighteenth-century structures that have been preserved in the county. The house still stands in downtown Knoxville. The Alexander McMillan House, built in the mid-1780s by Alexander McMillan (1749–1837), still stands in eastern Knox County. The Alexander Bishop House, built by Stockley Donelson in 1793, and a log house built in the same year by Nicholas Gibbs both still stand in the northern part of the county. Campbell's Station, a fort and stagecoach stop located in what is now Farragut, was built by Captain David Campbell (1753–1832) in 1787. John Sevier established a plantation, known as Marble Springs, in the southern part of the county in the 1790s. He was active in leading raids against the Cherokee people, who for years resisted with force American settlement in their territory.

### Civil War

Important railroad lines passed through Knox County, making it a strategic area both for Union and for Confederate forces throughout the Civil War. Since the mountainous terrain of East Tennessee was mostly unsuitable for plantation crops such as cotton, slavery was not as prevalent as it was in Middle and West Tennessee. The US 1860 census of Knox County showed a population of 20,020 white citizens and 2,370 enslaved African Americans. The lack of slavery combined with the vestiges of a once-strong abolitionist movement were two reasons most residents of Knox County, along with much of East Tennessee, were pro-Union. In February 1861, 89% of Knox Countians voted for the pro-Union ballot in a statewide referendum on secession. On June 8, 1861, the county voted against Tennessee's Ordinance of Secession by a margin of 3,108 to 1,226.
Prior to secession, Unionists from Knox County collaborated with other East Tennessee Unionists in an attempt to secede from Tennessee itself and remain part of the Union. Oliver Perry Temple, a Knoxville lawyer, was named to a three-man commission to appear before the General Assembly in Nashville and request East Tennessee and pro-Union Middle Tennessee counties be allowed to secede from the state. The attempt failed. After the second state referendum for secession passed in 1861, Knox County and the rest of Tennessee joined the Confederacy.
Knox County remained under Confederate control until September 3, 1863, when General Ambrose Burnside and the Union army marched into Knoxville unopposed. Parts of Middle Tennessee had been occupied by Union troops since 1862.
Union Colonel William Harris, son of New York Senator Ira Harris, wrote his father:
   'Glory be to God, the Yankees have come! The flag's come back to Tennessee!' Such were the welcomes all along the road, as we entered Knoxville, it was past all description. The people seemed frantic with joy. I never knew what the Love of Liberty was before. The old flag has been hidden in mattresses and under carpets. It now floats to the breeze at every staff in East Tennessee. Ladies wear it – carry it – wave it! Little children clap their hands and kiss it.
With the success of Burnside's troops in the Knoxville Campaign, and especially during the decisive Battle of Fort Sanders, Knox County remained under Union control for the duration of the Civil War.

### Tennessee marble

In the late 19th and early 20th centuries, Knox County was an important venue for the quarrying and finishing of Tennessee marble, a type of limestone used in monument construction across the United States and Canada. Eleven quarries were operating in Knox County in 1882, and within ten years that number had doubled. Notable quarries in Knox included the Bond Quarry in Concord, an Evans Company quarry near Forks-of-the-River, and the Ross-Republic quarries near Island Home Park in South Knoxville. Finishing centers were located in Lonsdale and at the Candoro Marble Works in South Knoxville.

## Geography

According to the U.S. Census Bureau, the county has a total area of 526 square miles (1,360 km$^2$), of which 508 square miles (1,320 km$^2$) is land and 18 square miles (47 km$^2$) (3.4%) is water. The county lies amidst the Ridge-and-Valley Appalachians, which are characterized by long, narrow ridges, oriented northeast-to-southwest, alternating with similarly shaped valleys. Notable ridges in the county include Bays Mountain, McAnnally Ridge, Beaver Ridge, Sharp's Ridge and Copper Ridge. House Mountain, at 2,064 feet (629 m), is the county's highest point, and is the focus of a state natural area.
The Holston and French Broad rivers join to form the Tennessee River in the eastern part of the county, an area known as "Forks-of-the-River." This section of the river is part of Fort Loudoun Lake, which is created by Fort Loudoun Dam on the river several miles downstream in Lenoir City.

### Cherokee Caverns

Cherokee Caverns is 14 miles west of Knoxville and can be accessed by Highway 62. It was discovered in 1854 by Robert Crudgington, who noticed fog emerging between rocks on his farm. He dug the entrance open and explored the cave. His daughter Margaret Crudgington opened the cave to the public in 1929 under the name Gentrys Cave; the next year she changed the name to Grand Caverns.
The cave has been open to the public, sporadically, ever since, under a variety of names. It is currently called Cherokee Caverns, referring to the historic tribe who occupied this area at the time of European encounter.
Indian artifacts located in the cave indicate that another entrance to the cave existed at some time in the past.

## Government and politics

Like most counties in heavily-Unionist East Tennessee, Knox County has historically been strongly Republican. Although it is somewhat conservative for an urban county, it is notably less Republican than most of the rest of East Tennessee. This is largely due to the influence of Knoxville, which in recent years has had a tendency to vote Democratic in statewide races, has elected Democratic mayors, and regularly elects Democrats to the state legislature. However, the suburban and rural areas are among the most Republican areas of Tennessee and the South.
Presidentially, Franklin Roosevelt carried the county in three of his four presidential elections, while several nearby counties are among the only counties in the nation to have never supported a Democratic candidate for president in their entire existence. Nevertheless, Democratic candidates have crossed the 40-percent mark only seven times since Roosevelt's death. In 1964, it was nearly swept up in Lyndon Johnson's national landslide; Johnson lost the county by only 334 votes. Jimmy Carter in 1976 and Bill Clinton in 1992 and 1996 are the only Democrats since then to come reasonably close to carrying the county, losing it by single-digit margins; in Clinton's case with Tennessean Al Gore on the ticket. Gore lost the county by 17 points in 2000 during his own bid for president, but still managed 40 percent. The Democrats would not cross the 40 percent threshold again until 2020, when Joe Biden received over 41 percent of the county's vote.

The government of Knox County, Tennessee operates under a home rule format. The county administrator, formerly known as the County Executive, is called the County Mayor. There is also an elected county commission, which consists of 11 members. Knox County is divided into nine commission districts, with one commissioner elected from each district. Two commissioners are elected countywide and serve as at-large representatives. The county commissioners' districts do not correspond with those of the city of Knoxville, which has its own mayor and city council. Residents of the county living within Knoxville city limits vote both in city and in county elections, are represented by city and county mayors, and pay city and county taxes. While the administration appears to be duplicated, services tend to be separated. Knox County runs the local school and library systems. Knoxville maintains a police department independent of the county sheriff. The property assessor's office, tax offices, and the Metropolitan Planning Commission are combined between the city and county governments. All Knox County elections are conducted on a partisan basis.

### Executive branch

The county mayor is the head of the executive branch of Knox County Government. The current county mayor is Glenn Jacobs, better known by his WWE persona Kane. According to the county's charter, the mayor is the chief financial officer of the county, which includes developing the county's annual budget, approving county contracts, etc. Other responsibilities of the county mayor's office include maintaining county roads, highways and bridges, codes enforcement and operating the county's health department and library system.
The mayor has the authority to veto resolutions and ordinances passed by the Knox County Commission. A majority-plus-one vote is required to override a mayoral veto, unless the vetoed legislation was required to have a two-thirds vote for original passage. In such cases, a two-thirds vote of the commission is required to override the veto.

### Legislative branch

The Knox County Board of Commissioners is the legislative body of Knox County and consists of 11 members: nine elected at the district level and two elected countywide to serve at-large. Commissioners meet multiple times each month, with their primary business meetings being a monthly work session and a monthly voting meeting. During the work session, commissioners generally debate items on the monthly agenda and take a non-binding vote on each item in advance of the more formal voting meeting, which is generally held the following week.
The Board of Commissioners approves resolutions, ordinances, honorariums, road names, as well as most county contracts and large expenditures. Resolutions require a single vote for passage, while ordinances require two votes, or "two readings". The County Commission also serves as the appropriating body of the county and must approve an annual budget – presented by the mayor – which includes funding for the various county departments, including the Knox County Schools. The body also sets the property tax rate for the county.
