Pre-European era The first inhabitants of Tennessee were
Paleo-Indians who arrived about 12,000 years ago at the end of the
Last Glacial Period. Archaeological excavations indicate that the lower Tennessee Valley was heavily populated by Ice Age
hunter-gatherers, and Middle Tennessee is believed to have been rich with
game animals such as
mastodons. The names of the cultural groups who inhabited the area before European contact are unknown, but archaeologists have named several distinct cultural phases, including the
Archaic (8000–1000 BC),
Woodland (1000 BC–1000 AD), and
Mississippian (1000–1600 AD) periods. The Archaic peoples first domesticated dogs, and plants such as
squash,
corn,
gourds, and
sunflowers were first grown in Tennessee during the Woodland period. Later generations of Woodland peoples constructed the first mounds. Rapid civilizational development occurred during the Mississippian period, when Indigenous peoples developed organized
chiefdoms and constructed numerous ceremonial structures throughout the state. Spanish conquistadors who explored the region in the 16th century encountered some of the Mississippian peoples, including the
Muscogee Creek,
Yuchi, and
Shawnee. By the early 18th century, most Natives in Tennessee had disappeared, most likely wiped out by diseases introduced by the Spaniards. The Cherokee began migrating into what is now eastern Tennessee from what is now Virginia in the latter 17th century, possibly to escape expanding European settlement and diseases in the north. They forced the Creek, Yuchi, and Shawnee out of the state in the early 18th century. The Chickasaw remained confined to West Tennessee, and the middle part of the state contained few Native Americans, although both the Cherokee and the Shawnee claimed the region as their hunting ground. Cherokee peoples in Tennessee were known by European settlers as the
Overhill Cherokee because they lived west of the Blue Ridge Mountains. Overhill settlements grew along the rivers in East Tennessee in the early 18th century.
Exploration and colonization The first recorded European expeditions into what is now Tennessee were led by Spanish explorers
Hernando de Soto in 1540–1541,
Tristan de Luna in 1559, and
Juan Pardo in 1566–1567. In 1673, English fur trader
Abraham Wood sent an expedition from the
Colony of Virginia into
Overhill Cherokee territory in modern-day northeastern Tennessee. That same year, a French expedition led by missionary
Jacques Marquette and
Louis Jolliet explored the Mississippi River and became the first Europeans to map the Mississippi Valley. In 1682, an expedition led by
René-Robert Cavelier, Sieur de La Salle constructed
Fort Prudhomme on the
Chickasaw Bluffs in West Tennessee. By the late 17th century, French traders began to explore the Cumberland River valley, and in 1714, under Charles Charleville's command, established French Lick, a fur trading settlement at the present location of Nashville near the
Cumberland River. In 1739, the French constructed
Fort Assumption under
Jean-Baptiste Le Moyne de Bienville on the Mississippi River at the present location of Memphis, which they used as a base against the Chickasaw during the
1739 Campaign of the
Chickasaw Wars. , the first British settlement in Tennessee In the 1750s and 1760s,
longhunters from Virginia explored much of East and Middle Tennessee. Settlers from the
Colony of South Carolina built
Fort Loudoun on the
Little Tennessee River in 1756, the first British settlement in what is now Tennessee and the westernmost British outpost to that date. Hostilities erupted between the British and the Cherokees into
an armed conflict, and a
siege of the fort ended with its surrender in 1760. After the
French and Indian War, Britain issued the
Royal Proclamation of 1763, which forbade settlements west of the
Appalachian Mountains in an effort to mitigate conflicts with the Natives. But migration across the mountains continued, and the first permanent European settlers began arriving in northeastern Tennessee in the late 1760s. Most of them were
English, but nearly 20% were
Scotch-Irish. They formed the
Watauga Association in 1772, a semi-autonomous representative government, and three years later reorganized themselves into the
Washington District to support the cause of the
American Revolutionary War. The next year, after an unsuccessful petition to Virginia, North Carolina agreed to annex the Washington District to provide protection from Native American attacks. In 1775,
Richard Henderson negotiated a series of treaties with the Cherokee to sell the lands of the Watauga settlements at
Sycamore Shoals on the banks of the
Watauga River. An agreement to sell land for the
Transylvania Colony, which included the territory in Tennessee north of the Cumberland River, was also signed. Later that year,
Daniel Boone, under Henderson's employment, blazed a trail from
Fort Chiswell in Virginia through the
Cumberland Gap, which became part of the
Wilderness Road, a major thoroughfare into Tennessee and Kentucky. The Chickamauga, a Cherokee faction loyal to the British led by
Dragging Canoe, opposed the settling of the Washington District and Transylvania Colony, and in 1776 attacked
Fort Watauga at Sycamore Shoals. The warnings of Dragging Canoe's cousin
Nancy Ward spared many settlers' lives from the initial attacks. In 1779,
James Robertson and
John Donelson led two groups of settlers from the Washington District to the French Lick. These settlers constructed
Fort Nashborough, which they named for
Francis Nash, a
brigadier general of the
Continental Army. The next year, the settlers signed the
Cumberland Compact, which established a representative government for the colony called the
Cumberland Association. This settlement later grew into the city of Nashville. That same year
John Sevier led a group of
Overmountain Men from Fort Watauga to the
Battle of Kings Mountain in South Carolina, where they defeated the British. Three counties of the
Washington District broke off from
North Carolina in 1784 and formed the
State of Franklin. Efforts to obtain admission to the
Union failed, and the counties, now numbering eight, rejoined North Carolina by 1788. North Carolina ceded the area to the federal government in 1790, after which it was organized into the
Southwest Territory on May 26 of that year. The act allowed the territory to petition for statehood once the population reached 60,000. Administration of the territory was divided between the Washington District and the Mero District, the latter of which consisted of the Cumberland Association and was named for Spanish territorial governor
Esteban Rodríguez Miró. President
George Washington appointed
William Blount as territorial governor. The Southwest Territory recorded a population of 35,691 in the
first United States census that year, including 3,417 slaves.
Statehood and antebellum era 's "Map of the Tennassee State" (1796) As support for statehood grew among the settlers, Governor Blount called for elections, which were held in December 1793. The 13-member territorial House of Representatives first convened in Knoxville on February 24, 1794, to select ten members for the legislature's upper house, the council. The full legislature convened on August 25, 1794. In June 1795, the legislature conducted a census of the territory, which recorded a population of 77,263, including 10,613 slaves, and a poll that showed 6,504 in favor of statehood and 2,562 opposed. Elections for a constitutional convention were held in December 1795, and the delegates convened in Knoxville on January 17, 1796, to begin drafting a state constitution. During this convention, the name Tennessee was chosen for the new state. The constitution was completed on February 6, which authorized elections for the state's new legislature, the
Tennessee General Assembly. The legislature convened on March 28, 1796, and the next day, John Sevier was announced as the state's first governor. Tennessee was admitted to the Union on June 1, 1796, as the 16th state and the first created from federal territory. Tennessee reportedly earned the nickname "The Volunteer State" during the
War of 1812, when 3,500 Tennesseans answered a recruitment call by the General Assembly for the war effort. These soldiers, under
Andrew Jackson's command, played a major role in the American victory at the
Battle of New Orleans in 1815, the last major battle of the war. Several Tennesseans took part in the
Texas Revolution of 1835–36, including Governor
Sam Houston and Congressman and frontiersman
Davy Crockett, who was killed at the
Battle of the Alamo. The state's nickname was solidified during the
Mexican–American War when President
James K. Polk of Tennessee issued a call for 2,800 soldiers from the state, and more than 30,000 volunteered. '', plantation home of President
Andrew Jackson in Nashville Between the 1790s and 1820s, additional land cessions were negotiated with the Cherokee, who had established
a national government modeled on the
U.S. Constitution. In 1818, Jackson and Kentucky governor
Isaac Shelby reached an agreement with the Chickasaw to sell the land between the Mississippi and Tennessee Rivers to the United States, which included all of West Tennessee and became known as the "
Jackson Purchase". The Cherokee moved their capital from Georgia to the
Red Clay Council Grounds in southeastern Tennessee in 1832, due to new laws forcing them from their previous capital at
New Echota. In 1838 and 1839, U.S. troops
forcibly removed thousands of Cherokees and their black slaves from their homes in southeastern Tennessee and forced them to march to
Indian Territory in modern-day
Oklahoma. This event is known as the
Trail of Tears, and an estimated 4,000 died along the way. celebrating the 150th anniversary of Tennessee statehood. As settlers pushed west of the Cumberland Plateau, a slavery-based
agrarian economy took hold in these regions. Cotton planters used extensive slave labor on large
plantation complexes in West Tennessee's fertile and flat terrain after the Jackson Purchase. Cotton also took hold in the Nashville Basin during this time. Entrepreneurs such as
Montgomery Bell used slaves in the production of iron in the Western Highland Rim, and slaves also cultivated such crops as tobacco and corn throughout the Highland Rim. East Tennessee's geography did not allow for large plantations as in the middle and western parts of the state, and as a result, slavery became increasingly rare in the region. A strong
abolition movement developed in East Tennessee, beginning as early as 1797, and in 1819,
Elihu Embree of
Jonesborough began publishing the
Manumission Intelligencier (later
The Emancipator), the nation's first exclusively anti-slavery newspaper.
Civil War At the onset of the
American Civil War, most Middle and West Tennesseans favored efforts to preserve their slavery-based economies, but many Middle Tennesseans were initially skeptical of secession. In East Tennessee, most people favored remaining in the Union. In 1860, slaves composed about 25% of Tennessee's population, the lowest share among the states that joined the
Confederacy. Tennessee provided more Union troops than any other Confederate state, and the second-highest number of Confederate troops, behind Virginia. Due to its central location, Tennessee was a crucial state during the war and saw more military engagements than any state except Virginia. After
Abraham Lincoln was elected president in
1860, secessionists in the state government led by Governor
Isham Harris sought voter approval to sever ties with the United States, which was rejected in a referendum by a 54–46% margin in February 1861. After the Confederate
attack on Fort Sumter in April and Lincoln's call for troops in response, the legislature ratified an agreement to enter a military league with the Confederacy on May 7, 1861. On June 8, with Middle Tennesseans having significantly changed their position, voters approved a second referendum on secession by a 69–31% margin, becoming the last state to secede. In response, East Tennessee Unionists organized
a convention in Knoxville with the goal of splitting the region to form a new state loyal to the Union. In the fall of 1861, Unionist guerrillas in East Tennessee
burned bridges and attacked Confederate sympathizers, leading the Confederacy to invoke
martial law in parts of the region. Because of this, many southern unionists were sent fleeing to nearby Union states, particularly the
border state of
Kentucky. Other southern unionists, who stayed in Tennessee after the state's secession, either resisted the Confederate cause or eventually joined it. In March 1862, Lincoln appointed native Tennessean and
War Democrat Andrew Johnson as military governor of the state. , November 30, 1864 General
Ulysses S. Grant and the
U.S. Navy captured the Tennessee and Cumberland rivers in February 1862 at the battles of
Fort Henry and
Fort Donelson. Grant then proceeded south to Pittsburg Landing and held off a Confederate counterattack at
Shiloh in April in what was at the time the bloodiest battle of the war. Memphis fell to the Union in June after a
naval battle on the Mississippi River. Union strength in Middle Tennessee was tested in a series of Confederate offensives beginning in the summer of 1862, which culminated in General
William Rosecrans's
Army of the Cumberland routing General
Braxton Bragg's
Army of Tennessee at
Stones River, another one of the war's costliest engagements. The next summer, Rosecrans's
Tullahoma campaign forced Bragg's remaining troops in Middle Tennessee to retreat to Chattanooga with little fighting. During the
Chattanooga campaign, Confederates attempted to besiege the Army of the Cumberland into surrendering, but reinforcements from the
Army of the Tennessee under the command of Grant,
William Tecumseh Sherman, and
Joseph Hooker arrived. The Confederates were driven from the city at the battles of
Lookout Mountain and
Missionary Ridge in November 1863. Despite Unionist sentiment in East Tennessee, Confederates held the area for most of the war. A few days after the fall of Chattanooga, Confederates led by
James Longstreet unsuccessfully
campaigned to take control of Knoxville by attacking Union General
Ambrose Burnside's
Fort Sanders. The capture of Chattanooga allowed Sherman to launch the
Atlanta campaign from the city in May 1864. The last major battles in the state came when Army of Tennessee regiments under
John Bell Hood invaded Middle Tennessee in the fall of 1864 in an effort to draw Sherman back. They were checked by
John Schofield at
Franklin in November and completely dispersed by
George Thomas at
Nashville in December. On April 27, 1865, the
worst maritime disaster in American history occurred when the
Sultana steamboat, which was transporting freed Union prisoners,
exploded in the Mississippi River north of Memphis, killing 1,168 people. When the
Emancipation Proclamation was announced, Tennessee was largely held by Union forces and thus not among the states enumerated, so it freed no slaves there. Andrew Johnson declared all slaves in Tennessee free on October 24, 1864. Tennessee ratified the
Thirteenth Amendment, which outlawed slavery in every state, on April 7, 1865, and the
Fourteenth Amendment, which granted citizenship and equal protection under the law to former slaves, on July 18, 1866. Both amendments went into effect after Tennessee's readmission to the union due to the fact that other states had not yet ratified it. Johnson became vice president when Lincoln was
reelected, and president after Lincoln's
assassination in May 1865. On July 24, 1866, Tennessee became the first Confederate state to have its elected members readmitted to Congress.
Reconstruction and late 19th century The years after the Civil War were characterized by tension and unrest between blacks and former Confederates, the worst of which occurred in
Memphis in 1866. Because Tennessee had ratified the Fourteenth Amendment before its readmission to the Union, it was the only former secessionist state that did not have a military governor during
Reconstruction. The
Radical Republicans seized control of the state government toward the end of the war, and appointed
William G. "Parson" Brownlow governor. Under Brownlow's administration from 1865 to 1869, the legislature allowed African American men to vote, disenfranchised former Confederates, and with martial law, took action against the
Ku Klux Klan, which was founded in December 1865 in
Pulaski as a vigilante group to advance former Confederates' interests. In 1870,
Southern Democrats regained control of the state legislature, and over the next two decades, passed
Jim Crow laws to enforce
racial segregation. A total of 251
lynchings, predominately of Black people, took place in Tennessee. A number of epidemics swept through Tennessee in the years after the Civil War, including
cholera in 1873, which devastated the Nashville area, and
yellow fever in 1878, which killed more than one-tenth of Memphis's residents. Reformers worked to modernize Tennessee into a "
New South" economy during this time. With the help of Northern investors, Chattanooga became one of the first industrialized cities in the South. Northerners also began exploiting the coalfields and mineral resources in the Appalachian Mountains. To pay off debts and alleviate overcrowded prisons, the state turned to
convict leasing, providing prisoners to mining companies as
strikebreakers, which was protested by miners forced to compete with the system. An armed uprising in the Cumberland Mountains known as the
Coal Creek War in 1891 and 1892 resulted in the state ending convict leasing. Despite New South promoters' efforts, agriculture continued to dominate Tennessee's economy. The majority of freed slaves were forced into
sharecropping during the latter 19th century, and many others worked as agricultural wage laborers. In 1897, Tennessee celebrated its statehood centennial one year late with the
Tennessee Centennial and International Exposition in Nashville. A
full-scale replica of the
Parthenon in
Athens was designed by architect
William Crawford Smith and constructed for the celebration, owing to the city's reputation as the "Athens of the South".
Early 20th century construction camp site in 1933 Due to increasing racial segregation and poor standards of living, many black Tennesseans fled to industrial cities in the Northeast and Midwest as part of the first wave of the
Great Migration between 1915 and 1930. Many residents of rural parts of Tennessee relocated to larger cities during this time for more lucrative employment opportunities. During
Prohibition, illicit production of
moonshine became extremely common in East Tennessee, particularly in the mountains, and continued for many decades afterward. Sgt.
Alvin C. York of
Fentress County became one of the most famous and honored American soldiers of
World War I. He received the Congressional
Medal of Honor for single-handedly capturing an entire German machine gun regiment during the
Meuse–Argonne offensive. On July 9, 1918, Tennessee suffered the
worst rail accident in U.S. history when two passenger trains
collided head on in Nashville, killing 101 and injuring 171. On August 18, 1920, Tennessee became the 36th and final state necessary to ratify the
Nineteenth Amendment to the United States Constitution, which gave women the
right to vote. In 1925,
John T. Scopes, a high school teacher in
Dayton, was
tried and convicted for teaching
evolution in violation of the state's recently passed
Butler Act. Scopes was prosecuted by former
Secretary of State and presidential candidate
William Jennings Bryan and defended by attorney
Clarence Darrow. The case was intentionally publicized, and highlighted the
creationism-evolution controversy among religious groups. In 1926, Congress authorized the establishment of
a national park in the
Great Smoky Mountains, which was officially established in 1934 and dedicated in 1940. When the
Great Depression struck in 1929, much of Tennessee was severely impoverished even by national standards. As part of President
Franklin D. Roosevelt's
New Deal, the
Tennessee Valley Authority (TVA) was created in 1933 to provide electricity, jobs, flood control, improved waterway navigation, agricultural development, and economic modernization to the
Tennessee River Valley. The agency quickly grew into the country's largest electric utility and initiated a period of dramatic economic growth and transformation that brought many new industries and employment opportunities to the state. operators at the
Y-12 Plant in Oak Ridge during the
Manhattan Project During
World War II, East Tennessee was chosen for the production of weapons-grade
fissile enriched uranium as part of the
Manhattan Project, a
research and development undertaking led by the U.S. to produce the world's first
atomic bombs. The
planned community of
Oak Ridge was built to provide accommodations for the facilities and workers; the site was chosen due to the abundance of TVA electric power, its low population density, and its inland geography and topography, which allowed for the natural separation of the facilities and a low vulnerability to attack. The
Clinton Engineer Works was established as the production arm of the Manhattan Project in Oak Ridge, which enriched uranium at three major facilities for use in atomic bombs. The first of the bombs was detonated in
Alamogordo, New Mexico, in a test code-named
Trinity, and the second, nicknamed "
Little Boy", was
dropped on Imperial Japan at the end of World War II. After the war, the
Oak Ridge National Laboratory became an institution for scientific and technological research. King had traveled there to support
striking African American sanitation workers. in Knoxville The 1962
U.S. Supreme Court case
Baker v. Carr arose from a challenge to the longstanding rural bias of apportionment of seats in the Tennessee legislature and established the principle of "
one man, one vote". The construction of
Interstate 40 through Memphis became a national talking point on the issue of
eminent domain and
grassroots lobbying when the
Tennessee Department of Transportation (TDOT) attempted to construct the highway through the city's
Overton Park. A
local activist group spent many years contesting the project, and in 1971, the U.S. Supreme Court sided with the group and established the framework for
judicial review of government agencies in the
landmark case of
Citizens to Preserve Overton Park v. Volpe. TVA's construction of the
Tellico Dam in Loudon County became the subject of national controversy in the 1970s when the endangered
snail darter fish was reported to be affected by the project. After lawsuits by environmental groups, the debate was decided by the U.S. Supreme Court case
Tennessee Valley Authority v. Hill in 1978, leading to amendments of the
Endangered Species Act. was home to the
1996 Summer Olympics whitewater slalom events, the only Olympic sporting event ever held in the state. The
1982 World's Fair was held in Knoxville. Also known as the Knoxville International Energy Exposition, the fair's theme was "Energy Turns the World". The exposition was one of the most successful, and the most recent world's fair to be held in the U.S. In 1986, Tennessee held a yearlong celebration of the state's heritage and culture called "Homecoming '86". Tennessee celebrated its bicentennial in 1996 with a yearlong celebration called "Tennessee 200". A new state park that traces the state's history,
Bicentennial Mall, was opened at the foot of Capitol Hill in Nashville. The same year, the
whitewater slalom events at the Atlanta
Summer Olympic Games were held on the
Ocoee River in
Polk County. In 2002, Tennessee amended its constitution to establish a
lottery. In 2006, the state constitution
was amended to outlaw
same-sex marriage. This amendment was invalidated by the 2015 U.S. Supreme Court case
Obergefell v. Hodges. On December 23, 2008, the
largest industrial waste spill in United States history occurred at TVA's
Kingston Fossil Plant when more than 1.1 billion gallons of
coal ash slurry was accidentally released into the
Emory and
Clinch Rivers. The cleanup cost more than $1 billion and lasted until 2015. ==Geography==
