How did the War of 1812 affect the Federalist Party?

Numerous Federalists opposed the war because many of these men earned their living through trade. The conflict hampered the Federalists' ability to exchange with England. ... With the signing of the Treaty of Ghent in 1814 and the end of the War of 1812, many Americans viewed the Federalists as traitors.

The outcome of the War of 1812 weakened the federalists party, but the philosophy of a strong national government was carried on by the War Hawks, who were apart of the republican party. Some of the causes of the war were because of British army's taking workers off American ships to work on theirs. Also because the west believed it was Britain's fault for the Indian attack for giving them guns.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
