The first Vice-President under Abraham Lincoln, Hannibal Hamlin only narrowly missed out on being President, having been replaced as Vice President by Andrew Johnson only a month prior to Lincoln’s assassination.
A Republican like Lincoln unlike Johnson, Hannibal Hamlin was relatively unpopular with both the people and Lincoln, the latter of whom dropped him from his 1860 re-election ticket in favor of the Southerner Johnson.
Yet even after he finished his term as VP, Hannibal Hamlin went on to have a rather interesting career as a senator, Collector of the Port of Boston and foreign ambassador before retiring.
