Tennessee is a state located in the Southern United States. Tennessee borders eight other states: Kentucky and Virginia to the north; North Carolina to the east; Georgia, Alabama and Mississippi on the south; and Arkansas and Missouri on the Mississippi River to the west.
Tennessee attained statehood in 1796, becoming the sixteenth state to join the Union.
The state is divided geographically and by law into three Grand Divisions: East Tennessee, Middle Tennessee, and West Tennessee. Physiographically, East Tennessee includes the Blue Ridge area characterized by high mountains, including the Great Smoky Mountains and the Ridge and Valley region, in which numerous tributaries join to form the Tennessee River in the Tennessee Valley. The state's third- and fourth-largest cities, Knoxville and Chattanooga, are located in the Tennessee Valley.
To the west of East Tennessee lies the Cumberland Plateau, a region of flat-topped mountains separated by sharp valleys. West of the Cumberland Plateau in Middle Tennessee is the Highland Rim, an elevated plain that surrounds the Nashville Basin, characterized by rich, fertile farm country and high natural wildlife diversity. Nashville, the state's capital and second largest city, is in Middle Tennessee.
The landscape of West Tennessee is formed on the Gulf Coastal Plain, ranging from rolling hills just west of the Tennessee River to the region of lowlands, floodplains, and swamp land referred to as the Mississippi Delta region. Memphis, Tennessee's largest city, is on the banks of the Mississippi River in the southwestern corner of the state.
Tennessee is known as the "Volunteer State", a nickname earned during the War of 1812 because of the prominent role played by volunteer soldiers from Tennessee.
