The New England states threaten secession for trade reasons during the later part of the War of 1812. I think they even called a convention which was overtaken by events, namely a peace treaty.

Also Jackson threatened to send troops into South Carolina over “nullification”. If I remember this correctly South Carolina wanted lower tariffs, the Federal government wanted higher. So the South Carolina legislature nullified the federal law. Jackson threatened to send in troops to enforce federal law and hang those talking secession.

Sort of puts the cries of union forever in a different perspective, doesn’t it?
