Secession of Southern states was the withdrawal of eleven Southern states from the United States between December 1860 and June 1861, culminating in the creation of the Confederate States of America and the outbreak of the American Civil War. The crisis involved prominent figures and institutions such as Abraham Lincoln, Jefferson Davis, Stephen A. Douglas, John C. Calhoun, James Buchanan, Alexander H. Stephens, and legal arguments rooted in the United States Constitution and antebellum jurisprudence like Dred Scott v. Sandford. Political parties, sectional interests, and territorial disputes including the Missouri Compromise, the Compromise of 1850, and the Kansas–Nebraska Act shaped the secession movement and national response.
Southern secession emerged from a complex nexus of political, economic, and social tensions involving leaders and debates such as Henry Clay, Daniel Webster, John C. Breckinridge, William H. Seward, and institutions like the United States Congress, the Democratic Party, the Whig Party, and the Republican Party. Disputes over territorial governance in regions like Kansas Territory, the Oregon Territory, and debates over the expansion of slavery addressed by the Missouri Compromise and the Compromise of 1850 heightened sectionalism. Electoral outcomes including the 1860 presidential contest featuring Abraham Lincoln, John C. Breckinridge, Stephen A. Douglas, and John Bell—coupled with influence from publications like the Liberator and legal decisions such as Dred Scott v. Sandford—fueled secessionist rhetoric in state capitals like Charleston, South Carolina, Montgomery, Alabama, Richmond, Virginia, and Jacksonville, Florida.
State-level secession conventions convened delegates and politicians including Robert Toombs, Alexander Stephens, James H. Hammond, and Rufus King to draft ordinances and declarations citing perceived constitutional grievances and protections for slave codes and slaveholding interests. South Carolina led with its December 1860 ordinance and issued a formal declaration referencing events such as the Nullification Crisis and treaties like the Missouri Compromise; subsequent ordinances by Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee, and North Carolina followed. Documents and proclamations invoked legal scholars and past disputes involving figures such as John C. Calhoun and judgments from courts including the Supreme Court of the United States.
Delegates from seceding states met at the Montgomery Convention and drafted a constitution for the Confederate States of America, electing Jefferson Davis as provisional and then permanent president, with Alexander H. Stephens as vice president. The Confederate constitution borrowed language from the United States Constitution while asserting states' rights and explicit protections for slavery, influenced by politicians like Robert Barnwell Rhett and Howell Cobb. The provisional government organized its capital movement from Montgomery, Alabama to Richmond, Virginia and established departments and offices mirroring United States Cabinet positions and military structures with leaders such as Pierre Gustave Toutant-Beauregard and Joseph E. Johnston.
The federal response involved President James Buchanan's final months and President-elect Abraham Lincoln's early administration, including federal determinations over installations such as Fort Sumter, Fort Pickens, and Fort Sumter's garrison commanded by Major Robert Anderson. Lincoln's policies—resupply missions, the inaugural address and proclamations—intersected with actions by William H. Seward, Edwin M. Stanton, and naval officers operating from Charleston Harbor and Pensacola Navy Yard. The Confederate attack on Fort Sumter in April 1861, involving commanders like P. G. T. Beauregard, precipitated Lincoln's call for volunteers and the mobilization of union forces under officers such as Winfield Scott and Irvin McDowell.
Secession led directly to military campaigns and battles including First Battle of Bull Run, Battle of Fort Sumter, Peninsula Campaign, Antietam, Gettysburg, and operations in theaters like the Trans-Mississippi Theater and Western Theater. Commanders such as Ulysses S. Grant, Robert E. Lee, Stonewall Jackson, George B. McClellan, William T. Sherman, and Braxton Bragg shaped strategy, while naval engagements including the CSS Virginia and the USS Monitor influenced maritime warfare. Politically, the conflict altered party dynamics involving the Republican Party, the Democratic Party, and wartime measures like the Confiscation Acts and Lincoln's Emancipation Proclamation; international dimensions implicated governments such as Great Britain, France, and the Russian Empire.
Secession prompted intense constitutional debate among jurists and politicians including Abraham Lincoln, John C. Calhoun, Roger B. Taney, and legal theorists referencing cases like Dred Scott v. Sandford and doctrines from the Articles of Confederation era. Questions concerned the legality of unilateral withdrawal, the authority of the Supreme Court of the United States versus state courts, habeas corpus suspension under Lincoln referencing precedents from John Marshall-era jurisprudence, and congressional measures such as the Thirteenth Amendment following wartime legislative actions. Prominent legal arguments were advanced in publications, speeches, and pamphlets by figures like Salmon P. Chase, Edward Bates, and Charles Sumner.
After Confederate collapse in 1865, Reconstruction involved leaders and institutions such as Andrew Johnson, Ulysses S. Grant, Freedmen's Bureau, Congressional Reconstruction, and amendments including the Thirteenth Amendment, Fourteenth Amendment, and Fifteenth Amendment. Policies debated in Congress and implemented by military districts under commanders like Winfield Scott Hancock and Philip Sheridan aimed to restore Union authority in states like Virginia, Georgia, Texas, and South Carolina while addressing rights for formerly enslaved people represented by activists including Frederick Douglass and lawmakers such as Thaddeus Stevens and Charles Sumner. The period saw contested episodes including Black Codes, Klu Klux Klan, Compromise of 1877, and judicial rulings by the Supreme Court of the United States that shaped the long-term legal and political reintegration of the Southern states.
