Jefferson Davis in the context of "United States Secretary of War"

The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States between the Union ("the North") and the Confederacy ("the South"), which was formed in 1861 by states that had seceded from the Union to preserve African American slavery, which they saw as threatened because of the election of Abraham Lincoln and the growing abolitionist movement in the North.

Decades of controversy over slavery came to a head when Abraham Lincoln, a Republican who opposed slavery's expansion, won the 1860 presidential election. Seven Southern slave states responded to Lincoln's victory by seceding from the United States and forming the Confederacy. The Confederacy seized US forts and other federal assets within its borders. The war began on April 12, 1861, when the Confederacy bombarded Fort Sumter in South Carolina. A wave of enthusiasm for war swept over the North and South, as military recruitment soared. Four more Southern states seceded after the war began and, led by its president, Jefferson Davis, the Confederacy asserted control over a third of the US population in eleven states. Four years of intense combat, mostly in the South, ensued.

Mississippi was the second southern state to declare its secession from the United States, doing so on January 9, 1861. It joined with six other southern states to form the Confederacy on February 4, 1861. Mississippi's location along the lengthy Mississippi River made it strategically important to both the Union and the Confederacy; dozens of battles were fought in the state as armies repeatedly clashed near key towns and transportation nodes.

Mississippian troops fought in every major theater of the American Civil War, although most were concentrated in the Western Theater. Confederate president Jefferson Davis was a Mississippi politician and operated a large cotton plantation there. Prominent Mississippian generals during the war included William Barksdale, Carnot Posey, Wirt Adams, Earl Van Dorn, Robert Lowry, and Benjamin G. Humphreys.

Georgia was one of the original seven slave states that formed the Confederate States of America in February 1861, triggering the U.S. Civil War. The state governor, Democrat Joseph E. Brown, wanted locally raised troops to be used only for the defense of Georgia, in defiance of Confederate president Jefferson Davis, who wanted to deploy them on other battlefronts. When the Union blockade prevented Georgia from exporting its plentiful cotton in exchange for key imports, Brown ordered farmers to grow food instead, but the breakdown of transport systems led to desperate shortages.

There was not much fighting in Georgia until September 1863, when Confederates under Braxton Bragg defeated William S. Rosecrans at Chickamauga Creek. In May 1864, William T. Sherman started pursuing the Confederates towards Atlanta, which he captured in September, in advance of his March to the Sea. This six-week campaign destroyed much of the civilian infrastructure of Georgia, decisively shortening the war. When news of the march reached Robert E. Lee's army in Virginia, whole Georgian regiments deserted, feeling they were needed at home. The Battle of Columbus, fought on the Georgia-Alabama border on April 16, 1865, is reckoned by some criteria to have been the last battle of the war.

The American state of Virginia became a prominent part of the Confederacy when it joined during the American Civil War. As a Southern slave-holding state, Virginia held the state convention to deal with the secession crisis and voted against secession on April 4, 1861. Opinion shifted after the Battle of Fort Sumter on April 12, and April 15, when U.S. President Abraham Lincoln called for troops from all states still in the Union to put down the rebellion. For all practical purposes, Virginia joined the Confederacy on April 17, though secession was not officially ratified until May 23. A Unionist government was established in Wheeling and the new state of West Virginia was created by an act of Congress from 50 counties of western Virginia, making it the only state to lose territory as a consequence of the war. Unionism was indeed strong also in other parts of the State, and during the war the Restored Government of Virginia was created as rival to the Confederate Government of Virginia, making it one of the states to have 2 governments during the Civil War.

In May, it was decided to move the Confederate capital from Montgomery, Alabama, to Richmond, Virginia, in large part because, regardless of the Virginian capital's political status, its defense was deemed vital to the Confederacy's survival. On May 24, 1861, the U.S. Army moved into northern Virginia and captured Alexandria without a fight. Most of the battles in the Eastern Theater of the American Civil War took place in Virginia because the Confederacy had to defend its national capital at Richmond, and public opinion in the North demanded that the Union move "On to Richmond!" The successes of Robert E. Lee in defending Richmond are a central theme of the military history of the war. The White House of the Confederacy, located a few blocks north of the State Capitol, became home to the family of Confederate leader, former Mississippi Senator Jefferson Davis.

The conclusion of the American Civil War commenced with the articles of surrender agreement of the Army of Northern Virginia on April 9, at Appomattox Court House, by General Robert E. Lee and concluded with the surrender of CSS Shenandoah on November 6, 1865, bringing the hostilities of the American Civil War to a close. Legally, the war did not end until a proclamation by President Andrew Johnson on August 20, 1866, when he declared "that the said insurrection is at an end and that peace, order, tranquillity, and civil authority now exist in and throughout the whole of the United States of America." The Confederate government being in the final stages of collapse, the war ended by debellatio, with no definitive capitulation from the rapidly disintegrating Confederacy; rather, Lee's surrender marked the effective end of Confederate military operations. The Confederate cabinet held its final meeting on May 5, at which point it declared the Confederacy dissolved, ending its substantive existence; despite this, some remnant Confederate units did not surrender for another month.

Lee's defeat on April 9 began the effective end of the war, after which there was no substantial resistance, but the news of his surrender took time to spread and some fighting continued, though only small skirmishes. President Abraham Lincoln lived to see Lee's surrender after four bloody years of war, but he was assassinated just five days later. The Battle of Columbus, Georgia, was fought on April 16, the day after Lincoln died. For the most part though, news of Lee's defeat led to a wave of Confederate surrenders. Gen. Joseph E. Johnston surrendered his large Army of Tennessee and the Southeastern Department on April 26. The Confederate cabinet was dissolved on May 5, and Confederate president Jefferson Davis was captured by Union soldiers on May 10, one day after Lincoln's successor, Andrew Johnson, declared that the belligerent rights of the Confederacy were at an end, with the rebellion effectively over.

The Confederate States Army (CSA), also called the Confederate army or the Southern army, was the military land force of the Confederate States of America (commonly referred to as the Confederacy) during the American Civil War (1861–1865), fighting against the United States forces to support the rebellion of the Southern states and uphold and expand the institution of slavery. On February 28, 1861, the Provisional Confederate Congress established a provisional volunteer army and gave control over military operations and authority for mustering state forces and volunteers to the newly chosen Confederate States president, Jefferson Davis (1808–1889). Davis was a graduate of the United States Military Academy, on the Hudson River at West Point, New York, and colonel of a volunteer regiment during the Mexican–American War (1846–1848). He had also been a United States senator from Mississippi and served as U.S. Secretary of War under 14th president Franklin Pierce. On March 1, 1861, on behalf of the new Confederate States government, Davis assumed control of the military situation at Charleston Harbor in Charleston, South Carolina, where South Carolina state militia had besieged the longtime Federal Fort Sumter in Charleston harbor, held by a small U.S. Army garrison under the command of Major Robert Anderson (1805–1871). By March 1861, the Provisional Congress of the Confederate States meeting in the temporary capital of Montgomery, Alabama, expanded the provisional military forces and established a more permanent regular Confederate States Army.

An accurate count of the total number of individuals who served in the Military forces of the Confederate States (Army, Navy and Marine Corps) is not possible due to incomplete and destroyed/burned Confederate records; and archives. Estimates of the number of Confederate soldiers, sailors and marines are between 750,000 and over 1,000,000 troops. This does not include an unknown number of black slaves who were pressed into performing various tasks for the army, such as the construction of fortifications and defenses or driving wagons. Since these figures include estimates of the total number of soldiers who served at any time during the war, they do not represent the size of the army at any given date. These numbers also do not include sailors/marines who served in the Confederate States Navy.

Robert Edward Lee (January 19, 1807 – October 12, 1870) was a Confederate general whose early actions in the American Civil War led to his appointment as the overall commander of the Confederate States Army near the end of the war. He led the Army of Northern Virginia, the Confederacy's most powerful army, from 1862 until its surrender in 1865, earning a reputation as one of the war's most skilled tacticians.

A son of Revolutionary War officer Henry "Light Horse Harry" Lee III, Lee was a top graduate of the United States Military Academy and an exceptional officer and military engineer in the United States Army for 32 years. He served across the United States, distinguished himself during the Mexican–American War, and was Superintendent of the United States Military Academy. He married Mary Anna Custis, great-granddaughter of George Washington's wife Martha. He supported the legality of slavery and held hundreds of slaves. When Virginia declared its secession from the Union in 1861, Lee chose to follow his home state, despite his desire for the country to remain intact and an offer of a senior Union command. During the first year of the Civil War, he served in minor combat operations and as a senior military adviser to Confederate president Jefferson Davis.

Fairview is a small census-designated place on the boundary between Christian and Todd counties in the western part of the U.S. state of Kentucky. As of the 2020 census, the population was 258, down from the 2010 census total of 286, with 186 living in Christian County and 100 living in Todd County. It is chiefly notable as the birthplace of Jefferson Davis, later President of the Confederate States of America, and as the location of the Jefferson Davis State Historic Site.

Joseph Emory Davis (10 December 1784 – 18 September 1870) was an American lawyer who became one of the wealthiest planters in Mississippi in the antebellum era; he owned thousands of acres of land and was among the nine men in Mississippi who owned more than 300 slaves. He was the elder brother (by 23 years) of Jefferson Davis and acted as his surrogate father for several years. The younger Davis became a politician, U.S. Senator, and later President of the Confederacy.

In the 1820s, Joseph Davis developed the Hurricane Plantation at Davis Bend, Mississippi.
