Causes: Impressment and Tecumseh
Tensions with Britain grew due to impressment, where the British navy kidnapped American sailors.
On land, American settlers pushing west faced resistance from Native Americans led by the Shawnee chief Tecumseh. Britain supplied guns to Tecumseh's confederacy, hoping to stop U.S. expansion.
Angered by these actions, the United States declared war on Britain in 1812, a conflict sometimes called the "Second War of Independence."
