Question

How and why did the war of 1812 start and why did it end? please help

Answer 1

It ended with the exchange of ratifications of the Treaty of Ghent. In 1812, with President Madison in office, Congress declared war against the British. The war began with an attack on Canada, both as an effort to gain land and to cut off British supply lines to Tecumseh's Indian confederation, which had long troubled the US.
