The Civil War began in 1861 and ended in 1865. It was fought between the northern and southern states over the issues of states' rights and slavery. Key figures included Abraham Lincoln, Robert E. Lee, Ulysses S. Grant, and Jefferson Davis. Major events were South Carolina's secession from the Union in January 1861, the First Battle of Bull Run in July 1861, the Emancipation Proclamation in January 1863, Lee's surrender to Grant in April 1865, and Lincoln's assassination later that month. The war ultimately ended slavery and preserved the United States as one country.
