United States delegates who negotiated the Treaty of Ghent with Great Britain included five who served in Congress at some point in their careers: John Quincy Adams and Jonathan Russell of Massachusetts, Albert Gallatin of Pennsylvania, Henry Clay of Kentucky, and James A. Bayard of Delaware. The treaty initiated a lasting peace between the two countries.
His Britannic Majesty and the United States of America, desirous of terminating the War which has unhappily subsisted between the two Countries, and of restoring, upon principles of perfect reciprocity, Peace, Friendship and Good Understanding between them have, for that purpose appointed their respective Plenipotentiaries, . . .

War of 1812: The Treaty of Ghent
The Treaty of Ghent ended the War of 1812. Signed in Ghent, Belgium, on Christmas Eve, 1814, it was approved by the British Parliament on December 30; the United States Senate approved it for ratification on February 16, 1815. Though the war had no clear winner, the treaty restored pre-war territorial boundaries, returned prisoners, and strengthened the United States as a nation. The greatest loss was to American Indians: without the support of their British allies, they were left vulnerable to U.S. power and expansionism.
