The Hartford Convention, which took place from December 15, 1814 – January 5, 1815, was a meeting of New England Federalists who were dissatisfied with President Madison's trade policy and the ongoing War of 1812.

Among the resolutions adopted by the convention, the one that stands out is: The convention called for a constitutional amendment that would make it harder to declare war.

This was proposed as a way to prevent individual states from being dragged into conflicts that did not serve their interests. The convention did not call for the impeachment of President Madison, nor did it call for New England states to secede from the Union. The idea of making embargoes illegal was also not a resolution adopted by the convention.
