By 1860, decades of friction over slavery had deeply divided the nation. In the 1840s and ’50s, Northern opposition to the extension of slavery in the western territories increasingly caused the Southern states to fear that existing slaveholdings, which formed the economic base of the South, were also in danger.
Library of Congress, Washington, D.C.When Abraham Lincoln, candidate of the explicitly antislavery Republican Party, won the 1860 presidential election, seven Southern states (South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas) seceded from the Union to protect what they saw as their right to keep slaves.
The Southern states organized as the Confederate States of America. Jefferson Davis was named president of the Confederacy. The Northern states of the federal Union, under Lincoln, commanded more than twice the population of the Confederacy and held greater advantages in manufacturing and transportation capacity.
On July 21, 1861, the Confederates routed overconfident Union forces in the First Battle of Bull Run, near Manassas in northern Virginia. The defeat shocked the Union and provided an early indication that the conflict would last a long time.
President Lincoln issued the Emancipation Proclamation on January 1, 1863. This order declared that slaves in the Confederate states were free. The proclamation influenced foreign opinion, persuading the British and French to not offer the Confederates the diplomatic recognition or military aid they sought.

After the Confederate victory at Chancellorsville, Virginia, Lee invaded the North and engaged Union forces under George G. Meade at the Battle of Gettysburg in Pennsylvania in July 1863. Momentum swung to the Union side after this battle. Lee was pushed back into Virginia and from then on was forced to fight a defensive war. Lincoln delivered his famous Gettysburg Address the following November.

On April 14 Lincoln was shot in Washington, D.C., by Confederate sympathizer John Wilkes Booth. Lincoln died the following day. Vice President Andrew Johnson became president.
On April 26 Sherman received the surrender of Joseph E. Johnston in North Carolina. In Louisiana, Confederate troops under Kirby Smith surrendered to Federal commander Edward Canby on May 26. The port of Galveston, Texas, yielded to Union forces on June 2, and the greatest war on American soil was over.
The American Civil War saw the first aerial reconnaissance using balloons, systematic medical care of the wounded, soldiers voting from the field, and modern war production of armaments. So many died in the war that a system of government cemeteries had to be established to bury the dead.
The navies of both sides also played a key role in the Civil War. Submarines and ironclads were used in naval battles. After 1863 the Union navy blockaded some 3,500 miles (5,600 kilometers) of Confederate coastline. Lincoln dubbed the navy, “Uncle Sam’s web feet.”

Library of Congress, Washington, D.C.The Civil War was one of the earliest wars documented on film. Photographs of individuals, battlefields, soldiers’ camps, and more left a compelling record. Particularly notable were the many photographs taken by Mathew Brady. Many authors, including Walt Whitman and Julia Ward Howe, also created an enduring legacy of Civil War poems, songs, and stories.
