He was born Feb. 12, 1809, in Hardin County, Kentucky. He married Mary Todd, and they had four boys, only one of whom lived to maturity. In 1858 Lincoln ran against Stephen A. Douglas for Senator. He lost the election, but in debating with Douglas he gained a national reputation that won him the Republican nomination for President in 1860. Became elected as the sixteenth President in 1861.
As President, he built the Republican Party into a strong national organization. Further, he rallied most of the northern Democrats to the Union cause. On January 1, 1863, he issued the Emancipation Proclamation that declared forever free those slaves within the Confederacy. Lincoln thought slavery was illegal, and was willing to use force to defend Federal law and the Union. When Confederate batteries fired on Fort Sumter and forced its surrender, he called on the states for 75,000 volunteers. Four more slave states joined the Confederacy but four remained within the Union. The Civil War had begun.
Lincoln never let the world forget that the Civil War involved an even larger issue. This he stated most movingly in dedicating the military cemetery at Gettysburg: "that we here highly resolve 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."
After the civil war Lincoln was re-elected, this happened in 1864, as Union military triumphs heralded an end to the war. In his planning for peace, the President was flexible and generous, encouraging Southerners to lay down their arms and join speedily in reunion.
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. The opposite happened.
