The impact of the Treaty of Ghent, signed in 1814, on the United States and Britain was a return to pre-war boundaries after the War of 1812. The treaty effectively ended the war without any territorial changes or significant concessions. This resolution fostered better relations between the two nations, allowing them to focus on mutual interests and trade rather than conflict. It laid the groundwork for future diplomacy and contributed to a long period of peace between the United States and Britain.
