Abraham Lincoln became the United States' 16th President in 1861, issuing the Emancipation Proclamation that declared forever free those slaves within the Confederacy in 1863. The son of a Kentucky frontiersman, Lincoln had to struggle for a living and for learning. Lincoln made extraordinary efforts to attain knowledge while working on a farm, splitting rails for fences, and keeping store at New Salem, Illinois. He was a captain in the Black Hawk War, spent eight years in the Illinois legislature, and rode the circuit of courts for many years. His law partner said of him, "His ambition was a little engine that knew no rest." He married Mary Todd, and they had four boys, only one of whom lived to maturity.  In his planning for peace, the President was flexible and generous, encouraging Southerners to lay down their arms and join speedily in reunion. On Good Friday, April 14, 1865, Lincoln was assassinated at Ford's Theatre in Washington by John Wilkes Booth, an actor, who somehow thought he was helping the South. https://www.whitehouse.gov/1600/presidents/abrahamlincoln
