**The War of 1812** The War of 1812 is sometimes called America's "forgotten war," but it played an important role in shaping the United States, Canada, and relations with Britain. Fought between the United States and Great Britain from 1812 to 1815, the conflict grew out of long-standing tensions that had been building for years after the American Revolution. One major cause of the war was British interference with American trade. Britain was locked in a struggle with Napoleonic France, and both European powers tried to restrict neutral trade. American merchants often found their ships caught in the middle. The British also practiced impressment, forcing some sailors from American ships into the Royal Navy. To many Americans, this was a violation of national sovereignty and a reminder that Britain still did not fully respect the United States as an independent country. Another source of tension was the frontier. Many Americans believed that Britain was supporting Indigenous resistance to U.S. expansion in the Northwest Territory. Leaders such as Tecumseh, a Shawnee chief, tried to build a confederacy of Native nations to resist the spread of American settlement. While Indigenous nations had their own goals and reasons for fighting, many American politicians saw British involvement as a direct threat. In June 1812, President James Madison asked Congress to declare war. The decision was controversial. Many members of the Democratic-Republican Party supported the war, especially in the South and West, but Federalists in New England strongly opposed it because they depended on trade with Britain. The country entered the conflict divided and poorly prepared. The early American campaigns were difficult. U.S. attempts to invade Canada largely failed, and British and Canadian forces, supported by Indigenous allies, captured Detroit in 1812. Over time, however, the United States had some important successes. On the Great Lakes, American naval victories helped secure control of key waterways. In 1813, U.S. forces won the Battle of the Thames, where Tecumseh was killed. His death weakened Indigenous resistance in the region and damaged hopes for a united Native confederacy. The war reached a dramatic point in 1814 after Britain had defeated Napoleon and could send more troops to North America. British forces entered Washington, D.C., and burned several public buildings, including the Capitol and the White House. Soon after, they attacked Baltimore. During the bombardment of Fort McHenry, Francis Scott Key saw the American flag still flying and wrote the poem that later became "The Star-Spangled Banner." The final major battle took place in New Orleans in January 1815. General Andrew Jackson led American forces to a decisive victory over the British. Ironically, the battle happened after the Treaty of Ghent had already been signed in December 1814, but news of the treaty had not yet reached the armies. The Treaty of Ghent ended the war without major territorial changes. Still, the conflict had lasting effects. Americans came away with a stronger sense of national pride, while Canada developed its own memory of resisting invasion. For Indigenous nations, the war was devastating, as British support faded and U.S. expansion continued. The War of 1812 may not have produced a clear winner, but it helped define the future of North America.
