When did the delegates leave the Hartford Convention?

The delegates left the Hartford Convention on January 5, 1815. The convention convened in December 1814 to discuss grievances related to the War of 1812 and the political power of the Federalist Party. By the time the delegates departed, the war was coming to an end, which diminished the urgency of their discussions. Ultimately, the convention's resolutions were largely overlooked, and the Federalist Party declined in influence afterward.
