Today is the sesquicentennial anniversary of Lincoln’s second inaugural address, delivered a month before the end of the American Civil War. The speech briefly explains Lincoln’s redemptive vision of the war as a bloodletting for the country’s sins. Lincoln historian Gary Wills described in 1999 why the speech deserves its place in the Lincoln monument. He considers it even better than the Gettysburg Address. More recently, the above photo of the inaugural audience surfaced in 2008.
