Alexander Hamilton & Aaron burr were enemies politically and personally. In 1791, Burr took a Senate seat from Philip Schuyler, Hamilton’s powerful father-in-law. Schuyler was a powerful ally for him as secretary of the Treasury. Burr ran for the governor of New York in 1804 as an independent. Hamilton helped to convince New York Federalists not to support Burr. The Burr campaign failed, and he was defeated soundly.
In 1804, Burr challenged Hamilton to a duel. After aids tried to settle their differently amicably, the two met on the dueling grounds at Weehawken, New Jersey on the morning of July 11. Each fired once. Burr struck Hamilton who died the next day. Hamilton’s shot missed. Burr was indicted for murder in New York State, but never prosecuted. After completing his duties as Vice President in 1805, Burr entered into a conspiracy to wrest the lands west of the Mississippi River from Spain; these intrigues included the Louisiana Purchase. The rock where Hamilton laid his head was preserved. Eventually it was moved to become part of a monument atop the cliffs of Weehawken. The duel took place below the cliffs.
