The Civil War was a defining conflict in United States history, fought from 1861 to 1865 between the Union in the North and the Confederacy in the South. It divided the country, tested the survival of the United States, and changed the meaning of freedom, citizenship, and national unity.
The main cause of the Civil War was slavery. For decades, Americans had argued over whether slavery should continue and whether it should expand into new western territories. Other issues, such as states’ rights, economic differences, and political power, were also important, but slavery was at the center of the conflict.
Tensions grew stronger after Abraham Lincoln was elected president in 1860. Many Southern leaders feared that his election threatened the future of slavery. Several Southern states seceded from the United States and formed the Confederate States of America, with Jefferson Davis as their president.
The war began in April 1861, when Confederate forces attacked Fort Sumter in Charleston Harbor, South Carolina. After the attack, Lincoln called for troops, and more states chose sides. What many people expected to be a short conflict became a long and devastating war.
Both sides had important leaders and armies. Abraham Lincoln led the Union as president, while Jefferson Davis led the Confederacy. Military figures such as Ulysses S. Grant, Robert E. Lee, William Tecumseh Sherman, and Stonewall Jackson became closely connected with the war’s major campaigns and battles.
The Civil War included many important battles and turning points. Bull Run showed that the war would not be easy for either side. Antietam became the bloodiest single day in American military history. In 1863, Union victories at Gettysburg and Vicksburg helped shift the direction of the war against the Confederacy.
The meaning of the war changed with Lincoln’s Emancipation Proclamation, which took effect on January 1, 1863. It declared freedom for enslaved people in Confederate-controlled areas and allowed African American men to join the Union Army and Navy. The war became not only a fight to preserve the Union, but also a struggle connected to ending slavery.
The Civil War ended in 1865 with Union victory. Its consequences were enormous: hundreds of thousands of people died, slavery was abolished through the 13th Amendment, and the nation entered Reconstruction, a difficult period of rebuilding and redefining rights.
