The correct answer is 4. The Hartford Convention led to the end of the Federalist Party.

Explanation:

The Hartford Convention was held in Connecticut between December 1814 and January 1815 by members of the Federalist Party. In said convention, these representatives discussed issues related to the War of 1812 and expressed their lack of support for the American cause and the total lack of meaning of said conflict, thus demonstrating their total antinomy towards the Democratic-Republican Party that was holding the presidency through James Madison.

It was a risky political move, with which the Federalists sought to win popular support to force an end to the war and a reconciliation with the British Empire. But this movement failed due to the American victory in the conflict, which led the Federalist Party to total discredit and to its loss of support at the popular level.
