After Aaron Burr killed Alexander Hamilton in a duel, was Thomas Jefferson still friends with or correspond with him afterwards?(r/AskHistorians)
By the time the Burr-Hamilton duel occurred, Jefferson and Burr were barely speaking even though Burr was the Vice-President. This is due to the fact that during the Election of 1800, there was a serious movement to place Burr as the President over Jefferson when the election went to the House of Representatives. Burr alienated Republicans by taking the position that he would not defer to Jefferson, the party leader, if he was selected as President.
Part of the hostility that ultimately led up to the duel between Hamilton and Burr was in fact b/c Hamilton actively endorsed Jefferson, whom Hamilton thought was mistaken in many areas, he at least had principles that he adhered to, over Burr, whom Hamilton viewed as having no principle but personal ambition, and his fellow Federalist Adams. Hamilton’s endorsement was particularly powerful b/c even though he was on the downslope of his influence and power, he still controlled enough of the Federalist party to have the potential to swing a vote in the House and some have argued that Hamilton’s influence was what swung the eventual deciding vote, Federalist James Bayard of Delaware, to pick Jefferson over Burr.
Jefferson never forgave Burr after this election and basically cast Burr out of the Democratic-Republican party. Jefferson so distrusted Burr that he shut Burr out of the administration, only meeting Burr for dinner once every two weeks and only allowing Burr to meet with his Cabinet once a year. Burr further broke with Jefferson when he sided with the Federalists over the repeal of the Judiciary Act. Burr was also distrusted by the Federalists, whom he courted to try and get back to power, and after his fateful duel with Hamilton he lost all influence with the remnants of that party.
