Grand Divisions of Tennessee in the context of "Knoxville"

Tennessee (/ˌtɛnɪˈsiː/ , locally /ˈtɛnɪsi/), officially the State of Tennessee, is a landlocked state in the Southeastern region of the United States. It borders Kentucky to the north, Virginia to the northeast, North Carolina to the east, Georgia, Alabama, and Mississippi to the south, Arkansas to the southwest, and Missouri to the northwest. Tennessee is the 36th-largest by area and the 15th-most populous of the 50 states. According to the United States Census Bureau, the state's estimated population as of 2024 is 7.22 million.

Tennessee is geographically, culturally, and legally divided into three Grand Divisions of East, Middle, and West Tennessee. Nashville is the state's capital and largest city, and anchors its largest metropolitan area. Tennessee has diverse terrain and landforms, and from east to west, contains a mix of cultural features characteristic of Appalachia, the Upland South, and the Deep South. The Blue Ridge Mountains along the eastern border reach some of the highest elevations in eastern North America, and the Cumberland Plateau contains many scenic valleys and waterfalls. The central part of the state is marked by cavernous bedrock and irregular rolling hills, and level, fertile plains define West Tennessee. The state is twice bisected by the Tennessee River, and the Mississippi River forms its western border. The Great Smoky Mountains National Park, the nation's most visited national park, is in eastern Tennessee.

Knoxville is a city in Knox County, Tennessee, United States, and its county seat. Located on the Tennessee River within the Appalachian Mountains, it is the largest city in the Grand Division of East Tennessee. Knoxville had a population of 190,740 at the 2020 census, making it the third-most populous city in Tennessee. The Knoxville metropolitan area has an estimated 958,000 residents.

Settled in 1786, Knoxville was the first capital of Tennessee. The city struggled with geographic isolation throughout the early 19th century before the arrival of the railroad in 1855 led to an economic boom. The city was bitterly divided over the issue of secession during the American Civil War and was occupied alternately by the Confederate and Union armies, which culminated in the Battle of Fort Sanders in 1863. Following the war, Knoxville grew rapidly and became a major wholesaling and manufacturing center until the 1920s when the city's economy began to stagnate. During the Great Depression, Knoxville's manufacturing sector collapsed, the downtown area declined, and city leaders became entrenched in highly partisan political fights. Hosting the 1982 World's Fair helped reinvigorate the city, and revitalization initiatives by city leaders and private developers have spurred growth in the city, especially downtown.

East Tennessee is one of the three Grand Divisions of Tennessee defined in state law. Geographically and socioculturally distinct, it comprises approximately the eastern third of the U.S. state of Tennessee. East Tennessee consists of 33 counties, 30 located within the Eastern Time Zone and three counties in the Central Time Zone, namely Bledsoe, Cumberland, and Marion. East Tennessee is entirely located within the Appalachian Mountains, although the landforms range from densely forested 6,000-foot (1,800 m) mountains to broad river valleys. The region contains the major cities of Knoxville and Chattanooga, Tennessee's third and fourth largest cities, respectively, and the Tri-Cities, the state's sixth largest population center.

During the American Civil War, many East Tennesseans remained loyal to the Union even as the state seceded and joined the Confederacy. Early in the war, Unionist delegates unsuccessfully attempted to split East Tennessee into a separate state that would remain as part of the Union. After the war, a number of industrial operations were established in cities in the region. The Tennessee Valley Authority (TVA), created by Congress during the Great Depression in the 1930s, spurred economic development and helped to modernize the region's economy and society. The TVA would become the nation's largest public utility provider. Today, the TVA's administrative operations are headquartered in Knoxville, and its power operations are based in Chattanooga. Oak Ridge was the site of the world's first successful uranium enrichment operations, which were used to construct the world's first atomic bombs, two of which were dropped on Imperial Japan at the end of World War II. The Appalachian Regional Commission further transformed the region in the late 20th century.

Middle Tennessee is one of the three Grand Divisions of Tennessee that composes roughly the central portion of the state. It is delineated according to state law as 41 of the state's 95 counties. Middle Tennessee contains the state's capital and largest city, Nashville, as well as Clarksville, the state's fifth largest city, and Murfreesboro, the state's sixth largest city and largest suburb of Nashville. The Nashville metropolitan area, located entirely within the region, is the most populous metropolitan area in the state, and the Clarksville metropolitan area is the state's sixth most populous. Middle Tennessee is both the largest, in terms of land area, and the most populous of the state's three Grand Divisions.

Geographically, Middle Tennessee is composed of the Highland Rim, which completely surrounds the Nashville Basin. The Cumberland Plateau is located in the eastern part of the region. Culturally, Middle Tennessee is considered part of the Upland South. Commodity crops such as cotton and tobacco were cultivated by migrant settlers in the region in the antebellum era, who were largely dependent on the labor of enslaved African Americans. In addition, planters bred and trained livestock, such as the world-famous Tennessee Walking Horse, which was developed as a breed in the region during this time.

West Tennessee is one of the three Grand Divisions of Tennessee that roughly comprises the western quarter of the state. The region includes 21 counties between the Tennessee and Mississippi rivers, delineated by state law. Its geography consists primarily of flat lands with rich soil and vast floodplain areas of the Mississippi River. Of the three regions, West Tennessee is the most sharply defined geographically, and is the lowest-lying. It is both the least populous and smallest, in land area, of the three Grand Divisions. Its largest city is Memphis, the state's second most populous city.

West Tennessee was originally inhabited by the Chickasaw, and was the last of the three Grand Divisions to be settled by Europeans. The region officially became part of the United States with the Jackson Purchase in 1818, 22 years after Tennessee's statehood. As part of the Mississippi River basin, West Tennessee enjoys rich soil that led to large-scale cotton farming during the antebellum period that was heavily dependent on slave labor. As a result, it forms the northwestern tip of the Black Belt.
