Abraham Lincoln delivered his second inaugural address on March 4, 1865, during his second inauguration as President of the United States. At a time when victory over the secessionists in the American Civil War was within days and slavery was near an end, Lincoln did not speak of happiness, but of sadness. Some see this speech as a defense of his pragmatic approach to Reconstruction, in which he sought to avoid harsh treatment of the defeated South by reminding his listeners of how wrong both sides had been in imagining what lay before them when the war began four years earlier. Lincoln balanced that rejection of triumphalism, however, with recognition of the unmistakable evil of slavery, which he described in the most concrete terms possible.
John Wilkes Booth, David Herold, George Atzerodt, Lewis Paine, John Surratt and Edmund Spangler, some of the conspirators involved with Lincoln's assassination, were present in the crowd at the inauguration. The address is inscribed, along with the Gettysburg Address, in the Lincoln Memorial.
Lincoln used his Second Inaugural Address to touch on the question of Divine providence. He wondered what God's will might have been in allowing the war to come, and why it had assumed the terrible dimensions it had taken. He endeavored to address some of these dilemmas, using allusions taken from the Bible.
Lincoln reiterates the cause of the war, slavery, in saying "slaves constituted a peculiar and powerful interest. All knew that this interest was somehow the cause of the war".
