The effect of the Treaty of Ghent on the War of 1812 was the official end of hostilities between the United States and Great Britain, restoring the territorial status quo. Signed in December 1814, the treaty had no significant territorial changes or gains for either side, leading to a sense of relief but also disappointment among some who had hoped for changes. Importantly, it paved the way for improved relations between the two nations. The war is often credited with fostering a sense of American nationalism and identity, shaping future diplomatic interactions.
