Abraham Lincoln, a one-time U.S. representative from Illinois, is nominated for the U.S. presidency by the Republican National Convention meeting in Chicago, Illinois. Hannibal Hamlin of Maine was nominated for the vice presidency.
Lincoln, a Kentucky-born lawyer and former Whig representative to Congress, first gained national stature during his campaign against Democratic Senator Stephen Douglas of Illinois for a U.S. Senate seat in 1858. The senatorial campaign featured a remarkable series of public encounters on the slavery issue, known as the Lincoln-Douglas debates, in which Lincoln argued against the spread of slavery while Douglas maintained that each territory should have the right to decide whether it would become free or slave state. Lincoln lost the Senate race, but his campaign brought national attention to the young Republican Party. In 1860, Lincoln won the party’s presidential nomination.
