The War of 1812, frequently relegated to the margins of American history, played a decisive role in shaping the young republic. Dubbed the “Second War of Independence,” this conflict with Britain reaffirmed the sovereignty of the United States, silenced lingering doubts about its viability as a nation, and set the stage for a transformative era.

What followed was a period of economic expansion and territorial ambition, later celebrated as the “Era of Good Feelings.”
