The document summarizes the rivalry and duel between Aaron Burr and Alexander Hamilton. Both were prominent figures in the early United States. Their rivalry stemmed from political races where they opposed each other. This came to a head in a 1804 duel at Weehawken Heights, where Burr fatally shot Hamilton. Hamilton's death marked the decline of the Federalist party and ended the life of a key Founding Father, while Burr's political career was ruined by the unlawful duel.
