The presidency of Abraham Lincoln began on March 4, 1861, when he was inaugurated as the 16th President of the United States, and ended upon his assassination and death on April 15, 1865, 42 days into his second term. We are not enemies, but friends. We must not be enemies. Though passion may have strained, it must not break our bonds of affection. The mystic chords of memory, stretching from every battle-field, and patriot grave, to every living heart and hearth-stone, all over this broad land, will yet swell the chorus of the Union, when again touched, as surely they will be, by the better angels of our nature. In November 1863, Lincoln was invited to Gettysburg to dedicate the first national cemetery and honor the soldiers who had fallen.
