Abraham Lincoln warned the South in his inaugural address. "In your hands, my dissatisfied fellow countrymen, and not in mine, is the momentous event of civil war The government will not invade them .... You do not have any oath registered in heaven to destroy the government, while I shall have the most solemn oath to preserve, protect and defend ". Lincoln thought that the secession was illegal, and was willing to use force to defend Federal law and the Union. When the Confederate battery fired against Fort Sumter and forced its surrender, he called on states for 75,000 volunteers. Four more slave states joined the Confederacy but four remained within the Union. The civil war had begun. The son of a Kentucky border, Lincoln had to struggle to live and learn. Five months before receiving his party's nomination for President, he sketched his life:

Lincoln never let the world forget that the Civil War involved a much larger issue. This they said, mostly carried devoted to it the Military Cemetery at Gettysburg: "This is where we meet greatly that these dead shall not have died in vain, that this nation, under God, shall have a new birth of freedom and that government of the people , by the people, for the people, shall not perish from the earth. " Lincoln won re-election in 1864, while the military triumphs of the union announced an end to the war. In its plan of operation for peace, the President was flexible and generous, encouraging Southerners to deliver their weapons and to quickly enter the Union. The spirit that led him was clearly in his second Inaugural Address, now inscribed on one wall of the Lincoln Memorial in Washington, DC: "With malice toward none; with charity for all; with firmness in the right as God gives us to see the right, let us strive to finish the work in which we are involved; to bind up the nation's wounds .... "on Good Friday, on April 14, 1865, Lincoln was assassinated at Ford's Theatre in Washington, by John Wilkes Booth, an actor, who somehow thought that Lincoln was helping the south. The opposite was the result, for with Lincoln's death, the possibility of peace with magnificiencia had died.
