This document provides an overview of events leading up to the American Civil War from Lincoln's election in 1860 to early 1863. It summarizes that Southern states began seceding after Lincoln's election, forming the Confederate States of America. The Civil War began with the Confederate attack on Fort Sumter in April 1861. Early battles like Bull Run were Confederate victories, but the Union blockade and victories in the Western Theater increased Northern momentum. The Emancipation Proclamation transformed the war's focus to ending slavery and cutting the Confederacy in two at Vicksburg.
