The Gettysburg Address (1863)
On November 19, 1863, President Abraham Lincoln delivered the Gettysburg Address at the dedication of the Soldiers' National Cemetery in Gettysburg, Pennsylvania. Speaking for just two to three minutes, Lincoln transformed the meaning of the Civil War with fewer than 275 words. While he considered his remarks "a flat failure" compared to Edward Everett's two-hour oration, Lincoln's speech became one of the most quoted and influential addresses in American history, redefining the war as a struggle for equality and human freedom.
