The famous speech that began with "Four score and seven years ago" is Abraham Lincoln's Gettysburg Address, delivered on November 19, 1863. The speech was given at the dedication of the Soldiers' National Cemetery in Gettysburg, Pennsylvania, following one of the Civil War's bloodiest battles. In just a few short paragraphs, Lincoln eloquently emphasized themes of equality, democracy, and national unity, while honoring those who had sacrificed their lives. His call for a "new birth of freedom" aimed to ensure that the nation would remain dedicated to the principles of liberty and equality for all, making it one of the most revered speeches in American history.
