The Gettysburg Address stands as a marvelous example of oratory – perhaps unequaled in all of U.S. political history:

Saying precisely what Lincoln's aims were in his Address is a controversial historical question. Characterizing the means he employed and the lasting effects of the Address, however, is far less controversial. These means included the skillful use of the history, symbols, and rituals shared not just by Lincoln's immediate audience, but also by Americans on both sides of a war that threatened to tear the Union in two. On the face of things, Lincoln's purpose at Gettysburg was simple: to dedicate a cemetery to the Union's fallen dead. But the way he did this had much greater effects, for what at first appeared only as the dedication of a particular plot of land ended up having a decisive impact on how Americans conceive of themselves.
