Answer:
For an amendment to be made, two-thirds of the members of each house of Congress must approve it, and three-fourths of the states must ratify it. Congress decides whether the ratification will be by state legislatures or by popularly elected conventions in the several states (though in only one instance, that of the Twenty-First Amendment, which repealed prohibition, was the convention system used). In many U.S. states, proposed amendments to a state constitution must be approved by the voters in a popular referendum.

There were multiple reasons the War of 1812 happened, one of them being that Britain and France were battling, which caused Britain to restrict French trade from the United States, which didn't make Americans happy. Another reason was the United Kingdom didn't want the United States to expand and become powerful, as they may be deemed as a threat, so they supported Natives in keeping their land so Americans couldn't expand. The last reason I know of, was Britain would capture some of our troops and force them to join their army. These things lead to the War of 1812, which was followed by peace between the United Kingdom and the United States.
