Southern Unionist in the context of "White Southerners"

The Union is a term used to refer to the central government and loyal states of the United States during the American Civil War. Its military forces and civilian population resisted the purported secession of the slave states that formed the Confederate States of America following the 1860 election of Abraham Lincoln as president of the United States. Lincoln's administration asserted the permanency of the federal government and the continuity of the United States Constitution, and it refused to recognize the Confederate government.

Nineteenth-century Americans commonly used the term Union to mean either the federal government of the United States or the unity of the states within the federal constitutional framework. The Union can also refer to the people or territory of the states that remained loyal to the national government during the war. The loyal U.S states located mostly above the Mason–Dixon line were also known as the North, although four southern border states and the future state of West Virginia remained loyal to the Union, and Black Southerners and many Southern Unionists opposed secession and supported the Union war effort.

The American Civil War significantly affected Tennessee, with every county witnessing combat. During the War, Tennessee was a Confederate state, and the last state to officially secede from the Union to join the Confederacy. Tennessee had been threatening to secede since before the Confederacy was even formed, but would not officially do so until after the fall of Fort Sumter when public opinion throughout the state drastically shifted. Tennessee seceded in protest to President Lincoln's April 15 Proclamation calling forth 75,000 members of state militias to suppress the rebellion. Tennessee provided the second largest number of troops for the Confederacy, and would also provide more southern unionist soldiers for the Union Army than any other state within the Confederacy.

In February 1862, some of the war's first serious fighting took place along the Tennessee and Cumberland rivers, recognized as major military highways, and mountain passes such as Cumberland Gap were keenly competed-for by both sides. The Battle of Shiloh and the fighting along the Mississippi brought glory to the then little-known Ulysses S. Grant, while his area commander Henry Halleck was rewarded with a promotion to General-in-Chief. The Tullahoma campaign, led by William Rosecrans, drove the Confederates from Middle Tennessee so quickly that they did not take many casualties, and were strong enough to defeat Rosecrans soon afterward. At Nashville in December 1864, George Thomas routed the Army of Tennessee under John Bell Hood, the last major battle fought in the state.

During the American Civil War, North Carolina joined the Confederacy with some reluctance, mainly due to the presence of Southern Unionistsentiment within the state. A popular vote in February, 1861 on the issue of secession was won by the unionists but not by a wide margin.

This slight lean in favor of staying in the Union would shift towards the Confederacy in response to Abraham Lincoln's April 15 proclamation that requested 75,000 troops from all Union states, leading to North Carolina's secession. Similar to Arkansas, Tennessee, and Virginia, North Carolina wished to remain uninvolved in the likely war but felt forced to pick a side by the proclamation. Throughout the war, North Carolina widely remained a divided state. The population within the Appalachian Mountains in the western part of the state contained large pockets of Unionism. Even so, North Carolina would help contribute a significant amount of troops to the Confederacy, and channeled many vital supplies through the major port of Wilmington, in defiance of the Union blockade.

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.

The history of West Virginia stems from the 1861 Wheeling Convention, which was an assembly of northwestern Southern Unionist from northwestern counties of the state of Virginia. They formed the Restored Government of Virginia, which purported to represent the government of the entire state of Virginia but in fact only represented those areas controlled by the Union army. It was recognized as the official government of the state of Virginia by Congress, and it repealed the Ordinance of Secession that Virginia made at the start of the American Civil War (1861–1865). It created West Virginia from the western counties under Union Army control. The new state was formed and recognized by the U.S. Congress on June 20, 1863, and protected by the U.S. Army.

The area that comprises West Virginia was originally part of the British Virginia Colony (1607–1776) and the western part of the U.S. Commonwealth of Virginia (1776–1788), and state of Virginia (1788–1863). Western Virginia became sharply divided over the issue of secession from the Union, leading to the separation from Virginia, and formalized by West Virginia's admittance to the Union as a new state in 1863. West Virginia was one of five Civil War border states.

Newton Knight (November 10, 1829 – February 16, 1922) was an American farmer, soldier, and Southern Unionist in Mississippi, best known as the leader of the Knight Company, a band of Confederate Army deserters who resisted the Confederacy during the Civil War. Local legends tell of Knight and his men forming the "Free State of Jones" in the area in and around Jones County, Mississippi, at the height of the war. The nature and extent of the Knight Company's opposition to the Confederate government is disputed among historians. After the war, Knight joined the Republican Party and served in Mississippi's Reconstruction government as a deputy U.S. Marshal.

Knight has long been a controversial figure in the region, with people divided over his motives and actions. He and his allies developed a small mixed-race community in southeastern Mississippi. His interracial marriage with Rachel Knight was considered illegal, as Mississippi had banned interracial marriages before and after the war, except for a brief period during Reconstruction.

North Mississippi is a region in the northeastern portion of the U.S. state of Mississippi, consisting of Alcorn, Itawamba, Lee, Pontotoc, Prentiss, Tippah, Tishomingo, and Union counties. These counties share a unique cultural history that distinguishes them from other areas in the state of Mississippi. As of 2010, the counties have a combined population of 267,560. Tupelo is the largest city in the region, but other notable cities include Booneville, Corinth, New Albany, and Pontotoc.

The northeast Mississippi region is notable for its hilly terrain and infertile soil that made it unsuitable for cotton farming during the Antebellum period. During the American Civil War (1861–1865), northeast Mississippi was home to Southern Unionist sentiment. Woodall Mountain, the highest natural point in Mississippi, is located in the region. Dramatic poverty continued in the region until the establishment of the Tennessee Valley Authority in 1933. Growth in the manufacturing sector during the 1950s and 1960s provided an economic boom to the region, and today North Mississippi benefits from the presence of a large health service industry centered on Tupelo.

George Henry Thomas (July 31, 1816 – March 28, 1870) was an American general in the Union Army during the American Civil War and one of the principal commanders in the Western Theater.

Thomas served in the Mexican–American War, and despite being a Virginian whose home state would join the Confederate States of America during the Civil War, he was a Southern Unionist who chose to remain in the U.S. Army. Thomas won one of the first Union victories in the war, at Mill Springs in Kentucky, and served in important subordinate commands at Perryville and Stones River. His stout defense at the Battle of Chickamauga in 1863 saved the Union Army from being completely routed, earning him his most famous nickname, "the Rock of Chickamauga." He followed soon after with a dramatic breakthrough on Missionary Ridge in the Battle of Chattanooga. In the Franklin–Nashville Campaign of 1864, he achieved one of the most decisive victories of the war, destroying the army of Confederate General John Bell Hood, his former student at West Point, at the Battle of Nashville.
