The Nation divided over the War of 1812. New England Federalists opposed the war because it harmed their budding industry. Several Northern states met at Hartford to protest the war. They also discussed the possibility of secession if some concessions were not made, including repealing the 3/5 clause in the Constitution. The fact that three of the four presidents were Virginian showed that the 3/5 clause gave the South too much power. It also showed that secession was not only a southern thing but was an answer for the weaker section of the nation.
