Step-by-step explanation:
The cause for the peace at Ghent, Belgium being signed was primarily the negotiations being successful and the war ending. In 1814, British and U.S. diplomats met in Flanders, Belgium, to negotiate the Treaty of Ghent, which was signed in December of that year. The treaty aimed to end the conflict in the Americas and the boundaries between the United States and British Canada remained as they were before the war.
