What was the name of the meeting of Federalists opposed to the War of 1812?

The meeting of Federalists opposed to the War of 1812 was called the Hartford Convention. It met in Hartford, Connecticut, from December 15, 1814, to January 5, 1815, as New England Federalists protested the war and what they viewed as growing federal overreach.

Delegates came mainly from Massachusetts, Connecticut, and Rhode Island, with additional representatives from dissident counties in New Hampshire and Vermont. They discussed constitutional amendments, including restrictions on declaring war, admitting new states, and imposing trade embargoes. Some delegates also worried that the national government was weakening New England’s commercial and political influence.

The convention did not formally call for secession, although rumors and later political propaganda gave it a strongly disunionist reputation. Its timing proved disastrous for the Federalist Party. News of the Treaty of Ghent and Andrew Jackson’s victory at New Orleans reached the public soon afterward, making the delegates appear disloyal just as the war ended. The Kentucky Resolutions belonged to an earlier dispute over federal power, while the Annapolis Convention concerned the structure of the government before the Constitution.
