The Hartford convention was held to what?

The Hartford Convention, held from December 1814 to January 1815, was a gathering of New England Federalists who opposed the War of 1812 and sought to address their grievances against the federal government. Delegates discussed potential constitutional amendments to increase state power and limit the influence of the Southern and Western states. The convention ultimately aimed to protect New England's interests, but its timing coincided with the end of the war and the subsequent rise in national unity, leading to the decline of the Federalist Party.
