During the lead up to the war of 1812, and during the war itself, New England was at odds with the course taken by the presidency and the national government. This culminated with the Hartford convention in 1814, and the sending of delegates to Washington to discuss terms with the Federal government.
With the success of the Battle of New Orleans and the treaty of Ghent, these delegates were ridiculed and the Federalist party was discredited, so much so that it essentially disappeared from the national stage entirely.
My question is, what if the Hartford convention ended up supporting secession, and what if the peace treaty had failed? Would New England have tried to secede from the Union, and how would that have worked out?
If New England had seceded, and the war had continued, I could see New England essentially becoming a British Client state, and the South controlling the USA for a long time.
How plausible/possible is New England seceding, and what happens afterward? I'd love to get some feedback.
