The third one Americans were humiliated by British impressments and Britain’s support of Native Americans
Answer:
The United States declared war on Great Britain because Americans were humiliated by British impressments and Britain's support of Native Americans.
Explanation:
The War of 1812 was a military conflict between the United States and the British Empire that did not result in a territorial change, but resolved many of the problems that remained from the United States War of Independence. The United States declared war on several grounds, including trade restrictions imposed by the British war against France, forcing US merchant sailors to join the Royal Navy, British support for Indian tribes against the expansion of the United States, the outrage at the insulting national honor after the US humiliation on the high seas and the US desire to annex Canada.
