Explanation:

The Treaty of Ghent, signed on 24 December 1814, was a peace treaty between the United States and the United Kingdom that put an end to the War of 1812 (1812-1815). The Treaty ceased all hostilities, restored the borders between the United States and British North America (which would later Canada) to prewar status, and restored diplomatic relations between both countries.

The War of 1812 wasn't popular in many northern states of the US, especially in New England, as the war had crippled the New England economy because of its major economic and trade links with British North America. The then ruling party in New England, the Federalist Party, opposed the war because of this and campaigned for peace with the British. When the Treaty of Ghent was signed, there was a backlash against the Federalist Party, as Americans from other states believed the party wanted the northern states to secede from the United States and join with Britain. However, the Federalists in New England took a moderate position, as they recognized that any moves towards secession would likely trigger a major conflict, and they worked towards restoring trade with the British instead.
