History Professor Allen Guelzo was published on the New York Times' Disunion Blog. His story focuses on President Lincoln's Gettysburg Address and his message to have faith in democracy.
From the New York Times' Disunion Blog:
The surprisingly short story of the Gettysburg Address is that it was a surprisingly short speech — 270 words or so — delivered by Abraham Lincoln as part of the dedication ceremonies for the Soldiers’ National Cemetery at Gettysburg, on Nov. 19, 1863, four and a half months after the climactic battle of the American Civil War.
But the long story is that no single American utterance has had the staying power, or commanded the respect and reverence, accorded the Gettysburg Address. It has been engraved (on the south wall of the Lincoln Memorial), translated (in a book devoted to nothing but translations of the address), and analyzed in at least nine book-length critical studies over the last century.
