Why did US enter the War of 1812?
They entered because when Britain and France began having a war,
the US didn't take any sides. France and Britain were not happy
that the US didn't take any sides, so they began taking American
ships by force. Great Britain also captured sailors from the US and
forced them to work for their navy. This made the US mad. They
deeply wanted to drive the Spanish out of Florida and British out
of Canada and fight Britain for the second time! So, they did so,
and it began the War of 1812.
