1863 – U.S. President Abraham Lincoln delivers the Gettysburg Address

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 this day in 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, was one of the greatest and most influential statements of national purpose. 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.
