The famous American speech that begins with "Four score and seven years ago" is Abraham Lincoln's Gettysburg Address. Delivered on November 19, 1863, during the dedication of the Soldiers' National Cemetery in Gettysburg, Pennsylvania, the speech is renowned for its eloquence and brevity. In just a few moments, Lincoln reminded his audience of the principles of human equality as espoused by the Declaration of Independence. He emphasized the sacrifices made by soldiers in the Civil War and redefined the war as a struggle not just for the Union, but for the principle of human liberty itself. This speech remains one of the most quoted in American history.
