Answer
A conflict between the United States and the British Empire (including British North America) from June 18, 1812 to February 17, 1815, fought over British impressment of American sailors, US territorial ambitions in Canada, and Indigenous resistance to American expansion; it ended with the Treaty of Ghent restoring pre-war borders.
Explanation
The War of 1812 was a conflict between the United States and the British Empire (including British North America) from June 18, 1812 to February 17, 1815. The war was fought primarily over British impressment of American sailors during the Napoleonic Wars, US territorial ambitions in Canada, and Indigenous resistance to American expansion led by the Shawnee chief Tecumseh. The war ended with the Treaty of Ghent (signed December 24, 1814, ratified February 17, 1815) restoring pre-war borders and resolving none of the immediate issues. For Canada the war is considered a key formative event in the development of British North American identity.
The United States declared war on Britain on June 18, 1812 under President James Madison. American leaders, particularly the 'War Hawks' from the South and West, expected an easy conquest of Canada. Former US President Thomas Jefferson predicted that taking Canada would be 'a mere matter of marching'. Britain, preoccupied with the Napoleonic Wars, had only about 5,200 regular British soldiers in all of British North America. However, the Canadian colonies were defended by these regulars, by Canadian militia (about 11,000 in Upper and Lower Canada), and by Indigenous allies including the Haudenosaunee and the western confederacy of Tecumseh.
The war's three years saw multiple campaigns. The British captured Fort Mackinac (July 17, 1812) and Detroit (August 16, 1812) under Major-General Isaac Brock. Brock was killed at the Battle of Queenston Heights on October 13, 1812, defeating the American invasion of the Niagara Peninsula. The Americans won the Battle of York on April 27, 1813 (burning the Upper Canadian Parliament Buildings) and the Battle of Lake Erie on September 10, 1813. Tecumseh was killed at the Battle of the Thames on October 5, 1813. British forces burned the White House and US Capitol on August 24, 1814 in retaliation for the burning of York. The Battle of Lundy's Lane on July 25, 1814 was one of the bloodiest engagements; Britain held the field. The Battle of New Orleans on January 8, 1815 was fought after the Treaty of Ghent was signed but before news arrived in America.
The war's outcomes for British North America were significant. The territorial integrity of the Canadian colonies was preserved. Indigenous resistance to American expansion collapsed after Tecumseh's death, and Britain abandoned its Indigenous allies in the Great Lakes region in the Treaty of Ghent. Canadian identity was strengthened by shared experience of resisting American invasion. The war produced enduring Canadian heroes including Brock (the 'Hero of Upper Canada'), Charles-Michel de Salaberry (who repulsed the Americans at Châteauguay on October 26, 1813), Laura Secord, and Tecumseh. The Battle of Queenston Heights, the Battle of the Châteauguay, the Battle of Crysler's Farm (November 11, 1813), and other Canadian victories are commemorated by Parks Canada national historic sites.
Why this matters for your test
The War of 1812 secured Canada's territorial integrity from American invasion and helped shape Canadian identity. Recognising the 1812 to 1815 dates and the Treaty of Ghent ending the war gives candidates two specific anchors.
