The National Union (Republican) ticket was officially elected on Dec. 7, 1864, when the nation’s presidential electors met and cast 212 Electoral votes for Lincoln-Johnson and 21 votes for McClellan-Pendleton.

As the American Civil War was still raging, no electoral votes were counted from any of the eleven Southern states.

The electors’ votes would be tabulated and certified on Feb. 8, 1865, during a joint session of Congress.

Lincoln’s victory made him the first president to win re-election since Andrew Jackson in 1832, as well as the first Northern president to ever win re-election.

Lincoln and Johnson would be inaugurated on March 4, 1865 (the beginning of Lincoln’s second term as president and Johnson’s first term as VP, succeeding incumbent VP Hannibal Hamlin).
