Civil War (United States) was a four-year conflict from 1861 to 1865 between the Union and the Confederacy that transformed the United States politically, socially, and economically. Sparked by disputes over slavery in the United States, territorial expansion, and states' rights, the war involved major campaigns fought across the Eastern Theater, Western Theater, and Trans-Mississippi Theater and culminated in Confederate surrender and federal policies aimed at integrating formerly enslaved people. The war featured military leaders, political figures, and social movements whose actions reverberated through Reconstruction and into modern American institutions.

Background and Causes

Tensions deepened after the Missouri Compromise and the Compromise of 1850 as partisan conflicts in the United States Congress intensified and events like the Kansas–Nebraska Act and the Dred Scott v. Sandford decision polarized national politics. The rise of the Republican Party and the election of Abraham Lincoln in 1860 prompted secession by Southern states led by figures such as Jefferson Davis and Alexander Stephens, who convened a constitutional convention to form the Confederate States of America. Violent clashes including John Brown's raid on Harper's Ferry and the Bleeding Kansas skirmishes illustrated the collapse of compromise, while economic disputes over tariffs and the expansion of cotton plantations tied to slave labor exacerbated sectional divisions.

Major Campaigns and Battles

The conflict's major campaigns included the First Battle of Bull Run and the Peninsula Campaign in the Eastern Theater, the Shiloh, Vicksburg Campaign, and Battle of Chattanooga in the Western Theater, and the Vicksburg siege that secured control of the Mississippi River. The 1863 battles of Gettysburg and Chancellorsville proved pivotal, as did Grant's Overland Campaign, including Wilderness and Spotsylvania Court House, and Sherman's Atlanta Campaign and subsequent March to the Sea through Georgia and the Carolinas Campaign. Naval engagements such as the Battle of Hampton Roads and blockade operations by the Union Navy shaped logistics, while the surrender at Appomattox Court House effectively ended large-scale Confederate resistance. Secondary theaters saw actions at Fort Sumter, New Orleans, Mobile Bay, and the Battle of Pea Ridge.

Military Forces and Leadership

Union forces coalesced under generals like Ulysses S. Grant, William Tecumseh Sherman, George B. McClellan, and George G. Meade, while Confederate leadership centered on Robert E. Lee, Stonewall Jackson, J.E.B. Stuart, and James Longstreet. The U.S. Regular Army expanded with volunteer regiments, while the Confederate Army of Northern Virginia and Army of Tennessee organized under state militias and centralized command. Naval innovation involved ironclads such as the USS Monitor and the CSS Virginia, and units like the United States Colored Troops and cavalry divisions under Nathan Bedford Forrest influenced reconnaissance and raiding. Logistics relied on railroads like the Baltimore and Ohio Railroad and telegraph lines exemplified by Western Union networks.

Home Front and Societal Impact

On the home front, leaders including Salmon P. Chase, Edwin Stanton, Jefferson Davis and Varina Davis managed wartime governance amid civil liberties controversies such as ex parte Merryman and suspension of habeas corpus. Northern industrial centers in New York City, Philadelphia, and Boston expanded manufacturing for ordnance and textiles, while Southern cities like Richmond, Virginia, Charleston, South Carolina, and Savannah, Georgia faced blockade, inflation, and labor disruptions. Social upheaval affected women activists such as Harriet Tubman, Clara Barton, and Mary Edwards Walker, and movements including the Underground Railroad and abolitionist networks led by William Lloyd Garrison and Frederick Douglass shaped public opinion. Draft laws prompted the New York City draft riots and political debates involving figures like Horace Greeley and Thaddeus Stevens.

Emancipation and Reconstruction Policies

The Emancipation Proclamation issued by Abraham Lincoln in 1863 reframed the war as a fight against slavery and authorized recruitment of African American soldiers into the United States Colored Troops, impacting campaigns and diplomacy with European powers such as Great Britain and France. Postwar Reconstruction involved constitutional amendments—the Thirteenth Amendment, Fourteenth Amendment, and Fifteenth Amendment—and legislation like the Civil Rights Act of 1866 and institutions including the Freedmen's Bureau and Union League. Political leaders such as Andrew Johnson and Radical Republicans like Charles Sumner and Benjamin Wade contested policies for readmission of former Confederate states and protection of citizenship rights, while the Ku Klux Klan and Black Codes resisted federal measures.

Casualties, Economics, and Technology

The war caused unprecedented casualties at battles including Antietam (Sharpsburg), Fredericksburg, and Petersburg, with estimates of total deaths exceeding 600,000 and widespread disease in army hospitals like those overseen by Dorothea Dix. Economic consequences included disruption of cotton exports, Northern manufacturing growth in cities such as Cleveland and Pittsburgh, Southern devastation of plantations, and fiscal policies like greenbacks issuance and wartime taxation administered by the Department of the Treasury under Salmon P. Chase. Technological innovations featured rifled muskets, repeating rifles like the Henry rifle, rail transport, steam warships, telegraphy, and medical advances from surgeons like Jonathan Letterman.

Legacy and Memory

The conflict's legacy shaped institutions such as the Supreme Court of the United States and debates over federal authority that surfaced in cases like Ex parte Milligan and political developments including the Gilded Age and Jim Crow laws. Commemoration produced monuments at Gettysburg National Military Park, National Mall, and battlefield preservation by organizations like the American Battlefield Trust. Cultural responses included poetry by Walt Whitman, novels like The Red Badge of Courage by Stephen Crane, and public memory shaped by veterans' groups such as the Grand Army of the Republic and the United Confederate Veterans. Modern scholarship by historians like James M. McPherson, Eric Foner, and Drew Gilpin Faust continues to reassess causes, conduct, and consequences for civil rights and constitutional development.
