What event is associated with boosted American national confidence and patriotism after the British invasions?

The War of 1812 is closely associated with a significant boost in American national confidence and patriotism, particularly following the challenges posed by British invasions and blockades during the conflict. After several years of fighting, the war culminated in key moments, such as the defense of Fort McHenry, which inspired Francis Scott Key to write "The Star-Spangled Banner," an anthem that symbolized national pride.

The outcomes of the War of 1812 fostered a sense of unity and resilience among Americans. The fact that the United States managed to withstand British military efforts and maintain its sovereignty contributed to an emerging national identity. Furthermore, subsequent victories and the conclusion of the war led to what was later termed the "Era of Good Feelings," a period marked by a surge in nationalistic spirit and confidence.

While other events like the Battle of Bunker Hill, the Battle of Saratoga, and the Battle of Yorktown were significant in their own right and influenced American history, they are tied to different conflicts and contexts. The War of 1812 specifically encapsulates the post-revolutionary struggle for independence and the development of a national consciousness in response to British aggression.
