The impact of the War of 1812 on American nationalism and identity was profound. This conflict, fought between the United States and Great Britain, fostered a sense of national unity and pride. The war's conclusion, especially the victory at the Battle of New Orleans, bolstered the image of the U.S. military and leaders like Andrew Jackson. Additionally, the war catalyzed the development of American manufacturing as the U.S. sought self-sufficiency while under British blockade. The conflict also paved the way for the Era of Good Feelings, a period marked by political harmony and a surge in nationalistic sentiment.
