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.
As President, he built the Republican Party into a strong national organization.
Lincoln never let the world forget that the Civil War involved an even larger issue, slavery.
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.
