full_context: Document 1: Confederate States Army: The Confederate States Army (C.S.A.) was the military ground force of the Confederate States of America (Confederacy) during the American Civil War (1861-1865). 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 president, Jefferson Davis (1808-1889), a graduate of the U.S. Military Academy on the Hudson River at West Point, New York, and colonel of a volunteer regiment during the Mexican–American War (1846-1848), later a United States Senator from Mississippi and U.S. Secretary of War in the administration of 14th President Franklin Pierce (1853-1857). By March 1861, the Provisional Confederate Congress expanded the provisional forces and established a more permanent Confederate States Army.
Document 2: Slave states and free states: In the history of the United States of America, a slave state was a U.S. state in which the practice of slavery was legal, and a free state was one in which slavery was prohibited or being legally phased out. Historically, all the British colonies had practiced slavery. The division between slave and free states began during the American Revolution (1775–1783). Slavery became a divisive issue and was the primary cause of the American Civil War. The Thirteenth Amendment to the United States Constitution, ratified in 1865, abolished slavery throughout the United States, and the distinction between free and slave states ended.
Document 3: Border states (American Civil War): In the context of the American Civil War (1861–1865), the border states were slave states that did not declare a secession from the Union and did not join the Confederacy. To their north they bordered free states of the Union and to their south they bordered Confederate slave states. Of the 34 U.S. states in 1861, nineteen were free states and fifteen were slave states. Four slave states never declared a secession: Delaware, Kentucky, Maryland, and Missouri. Four others did not declare secession until after the Battle of Fort Sumter and were briefly considered to be border states: Arkansas, North Carolina, Tennessee, and Virginia—after this, they were less frequently called “border states”. Also included as a border state during the war is West Virginia, which was formed from 50 counties of Virginia and became a new state in the Union in 1863.
Document 4: King Cotton: "King Cotton" as a slogan summarized the strategy used before the American Civil War of 1861–1865 by pro-secessionists in the Southern States (the future Confederacy) to claim the feasibility of secession and to prove there was no need to fear a war with the Northern States. The theory held that control over cotton exports would make a proposed independent Confederacy economically prosperous, would ruin the textile industry of New England, and—most importantly—would force Great Britain and perhaps France to support the Confederacy militarily because their industrial economies depended on Southern cotton. The slogan, widely believed throughout the South, helped in mobilizing support for secession: by February 1861, the seven states whose economies were based on cotton plantations had all seceded and formed the Confederacy (C.S.A.). Meanwhile, the other eight slave states, with little or no cotton production, remained in the Union.

Some slave states refused to send troops against their neighboring slave states, with the result that most such states also declared secession from the United States and joined the Confederate States.

The result of a long-standing controversy over slavery, war broke out in April 1861, when Confederates attacked Fort Sumter in South Carolina, shortly after Abraham Lincoln was inaugurated. The nationalists of the Union proclaimed loyalty to the U.S. Constitution. They faced secessionists of the Confederate States of America, who advocated for states’ rights to perpetual slavery and its expansion in the Americas.

The Confederacy also operated under a Provisional Constitution from February 8, 1861, to February 22, 1862. The original Provisional Constitution is currently located at the American Civil War Museum in Richmond, Virginia, and differs slightly from the version later adopted. The final, hand-written document is currently located in the University of Georgia archives at Athens, Georgia. In regard to most articles of the Constitution, the document is a word-for-word duplicate of the United States Constitution. However, there are crucial differences between the two documents, in tone and legal content, primarily regarding slavery.
