The results of the War of 1812, which was fought between the United Kingdom and the United States from 1812 to 1814, included no immediate boundary changes. The main result of the War of 1812 has been two centuries of peace between the two countries. The threat of secession by New England ended after the failure of the Hartford Convention. In Britain, the importance of the conflict was totally overshadowed by European triumphs since Napoleon returned from exile in March 1815, but he was finally defeated at the Battle of Waterloo a few months later.
