What is the gettsburg address?

The Gettysburg Address was a speech by President Lincoln to dedicate a cemetery for fallen soldiers. It was a short speech that many think is the best speech a US president has ever given. Lincoln's speech was highly metaphysical and gave honor to the soldiers who fought and died at the Battle of Gettysburg. Lincoln made it clear that there was much at stake for the United States and the government that had been created so long ago. Lincoln used "four score and seven years" to indicate he was not referring to the US Constitution but to the Declaration of Independence.
