As the war was drawing to a close, Lincoln became the first American president to be assassinated. Before his election in 1860 as the first Republican president, Lincoln had been a lawyer, an Illinois state legislator, a member of the United States House of Representatives, and twice an unsuccessful candidate for election to the Senate.
