What forces brought the destruction of the federalist party

The main conflict that contributed to the destruction of the Federalist Party was its opposition to the War of 1812.

The War of 1812 was conflict between the United States and Great Britain, which broke out due to the US refusal to the naval blockade that Britain was trying to enforce to avoid trade with Napoleonic France.

In New England, the war was a matter of concern since their economy was highly dependent on trade. For this reason, the federalists of New England sent delegates to the Hartford Convention in 1814 to negotiate Constitutional amendments. However, the Federalist Massachusetts Governor had already agreed a peace treaty with the British secretly. When the news spread, the federalists were considered by the public opinion to be disloyal, cowards and secessionists. At the end, this resulted in the destruction of the political party.
