<em>C. The Treaty of Ghent established peace.</em>
Explanation:
The Treaty of Ghent is known to be the treaty that established peace between the United Kingdom and the United States, as it ended the War of 1812.
The War of 1812 started for numerous reasons. One of them is that the United Kingdom closed the trade between the United States in France, which Americans did not agree with. The United Kingdom would also take Americans on sea vessels and force them to join the Royal Navy, which angered the Americans even more.
Eventually, the United States declared war in 1812. Numerous battles broke out like the Battle of Baltimore and the Battle of New Orleans. The Battle of Baltimore was where the United States turned the tide and the Battle of New Orleans was a victory for the United States.
The Treaty of Ghent was signed in 1814, but was officially ratified in 1815. The United Kingdom and the United States were now at peace with one another.
