Political and economic reasons behind the conflict.
The United States declared war on Britain on June 18, 1812, after years of maritime impressment, trade restrictions, and perceived British support for Indigenous resistance on the frontier. The decision followed President James Madison’s war message and reflected the competing pressures of honor, expansion, and political division.
President Thomas Jefferson imposed the Embargo Act of 1807 to protect American ships and sailors from British and French depredations and to coerce belligerents through economic pressure without war. The policy failed, damaged the American economy, and deepened sectional divisions that contributed to the War of 1812.
The Continental System was Napoleon’s economic blockade of British trade with Europe, beginning with the Berlin Decree of 1806. Its enforcement and Britain’s counter-blockade entangled the United States as a neutral trader and contributed directly to the American declaration of war in 1812.
