The Gettysburg Address is a speech by U.S. President Abraham Lincoln, one of the best-known in American history. It was delivered by Lincoln during the American Civil War, on the afternoon of Thursday, November 19, 1863, at the dedication of the Soldiers' National Cemetery in Gettysburg, Pennsylvania, four and a half months after the Union armies defeated those of the Confederacy at the Battle of Gettysburg. Abraham Lincoln's carefully crafted address, secondary to other presentations that day, came to be regarded as one of the greatest speeches in American history. In just over two minutes, Lincoln reiterated the principles of human equality espoused by the Declaration of Independence and proclaimed the Civil War as a struggle for the preservation of the Union sundered by the secession crisis, with "a new birth of freedom", that would bring true equality to all of its citizens. Lincoln also redefined the Civil War as a struggle not just for the Union, but also for the principle of human equality.
