American Civil War: Nathan Bedford Forrest surrenders his forces at Gainesville, Alabama.

Nathan Bedford Forrest (July 13, 1821 October 29, 1877) was a prominent Confederate Army general during the American Civil War and the first Grand Wizard of the Ku Klux Klan from 1867 to 1869. Before the war, Forrest amassed substantial wealth as a cotton plantation owner, horse and cattle trader, real estate broker, and slave trader. In June 1861, he enlisted in the Confederate Army and became one of the few soldiers during the war to enlist as a private and be promoted to general without any prior military training. An expert cavalry leader, Forrest was given command of a corps and established new doctrines for mobile forces, earning the nickname "The Wizard of the Saddle". He used his cavalry troops as mounted infantry and often deployed artillery as the lead in battle, thus helping to "revolutionize cavalry tactics", although the Confederate high command is seen by some commentators to have underappreciated his talents. Although scholars generally acknowledge Forrest's skills and acumen as a cavalry leader and military strategist, he has remained a controversial figure in Southern racial history for his main role in the massacre of several hundred Union soldiers at Fort Pillow, a majority of them black, coupled with his role following the war as a leader of the Klan.

In April 1864, in what has been called "one of the bleakest, saddest events of American military history", troops under Forrest's command at the Battle of Fort Pillow massacred hundreds of troops, composed of black soldiers and white Tennessean Southern Loyalists fighting for the Union, who had already surrendered. Forrest was blamed for the slaughter in the Union press, and this news may have strengthened the North's resolve to win the war. Forrest's responsibility for the massacre continues to be actively debated by historians.Forrest, who was a Freemason, joined the Ku Klux Klan in 1867 (two years after its founding) and was elected its first Grand Wizard. The group was a loose collection of local factions throughout the former Confederacy that used violence and the threat of violence to maintain white control over the newly enfranchised former slaves. The Klan, with Forrest at the lead, suppressed voting rights of blacks in the South through violence and intimidation during the elections of 1868. In 1869, Forrest expressed disillusionment with the lack of discipline in the white supremacist terrorist group across the South, and issued a letter ordering the dissolution of the Ku Klux Klan as well as the destruction of its costumes; he then withdrew from the organization. In the last years of his life, Forrest insisted he had never been a member. Just a few months before his death, Forrest attended an African-American barbecue in Memphis. Aiming to right his past wrongs, Forrest encouraged African-Americans to "work, be industrious, live honestly and act truly", as well as declaring that "when you are oppressed, I'll come to your relief".In June 2021, the remains of Forrest and his wife were exhumed from Health Sciences Park, where they had been buried for over 100 years and a monument of him once stood. They were later reburied in Columbia, Tennessee. In July 2021, Tennessee officials voted to move Forrest's bust from the State Capitol to the Tennessee State Museum.

The American Civil War (April 12, 1861 – May 9, 1865; also known by other names) was a civil war in the United States between the Union (states that remained loyal to the federal union, or "the North") and the Confederacy (states that voted to secede, or "the South"). The central cause of the war was the status of slavery, especially the expansion of slavery into territories acquired as a result of the Louisiana Purchase and the Mexican–American War. On the eve of the Civil War in 1860, four million of the 32 million Americans (~13%) were enslaved black people, almost all in the South.The practice of slavery in the United States was one of the key political issues of the 19th century. Decades of political unrest over slavery led up to the Civil War. Disunion came after Abraham Lincoln won the 1860 United States presidential election on an anti-slavery expansion platform. An initial seven southern slave states declared their secession from the country to form the Confederacy. Confederate forces seized federal forts within territory they claimed. The last-minute Crittenden Compromise tried to avert conflict but failed; both sides prepared for war. Fighting broke out in April 1861 when the Confederate army began the Battle of Fort Sumter in South Carolina, just over a month after the first inauguration of Abraham Lincoln. The Confederacy grew to control at least a majority of territory in eleven states (out of the 34 U.S. states in February 1861), and asserted claims to two more. Both sides raised large volunteer and conscription armies. Four years of intense combat, mostly in the South, ensued.

During 1861–1862 in the war's Western Theater, the Union made significant permanent gains—though in the war's Eastern Theater the conflict was inconclusive. On January 1, 1863, Lincoln issued the Emancipation Proclamation, which made ending slavery a war goal, declaring all persons held as slaves in states in rebellion "forever free." To the west, the Union destroyed the Confederate river navy by the summer of 1862, then much of its western armies, and seized New Orleans. The successful 1863 Union siege of Vicksburg split the Confederacy in two at the Mississippi River. In 1863, Confederate General Robert E. Lee's incursion north ended at the Battle of Gettysburg. Western successes led to General Ulysses S. Grant's command of all Union armies in 1864. Inflicting an ever-tightening naval blockade of Confederate ports, the Union marshaled resources and manpower to attack the Confederacy from all directions. This led to the fall of Atlanta in 1864 to Union General William Tecumseh Sherman and his march to the sea. The last significant battles raged around the ten-month Siege of Petersburg, gateway to the Confederate capital of Richmond.

The Civil War effectively ended on April 9, 1865, when Confederate General Lee surrendered to Union General Grant at the Battle of Appomattox Court House, after Lee had abandoned Petersburg and Richmond. Confederate generals throughout the Confederate army followed suit. The conclusion of the American Civil War lacks a clean end date: land forces continued surrendering until June 23. By the end of the war, much of the South's infrastructure was destroyed, especially its railroads. The Confederacy collapsed, slavery was abolished, and four million enslaved black people were freed. The war-torn nation then entered the Reconstruction era in a partially successful attempt to rebuild the country and grant civil rights to freed slaves.

The Civil War is one of the most studied and written about episodes in the history of the United States. It remains the subject of cultural and historiographical debate. Of particular interest is the persisting myth of the Lost Cause of the Confederacy. The American Civil War was among the earliest to use industrial warfare. Railroads, the telegraph, steamships, the ironclad warship, and mass-produced weapons saw wide use. In total the war left between 620,000 and 750,000 soldiers dead, along with an undetermined number of civilian casualties. President Lincoln was assassinated just five days after Lee's surrender. The Civil War remains the deadliest military conflict in American history. The technology and brutality of the Civil War foreshadowed the coming World Wars.
