Canada and the War of 1812
A by-product of the Napoleonic Wars that preoccupied most of Europe at the beginning of the 19th century, the War of 1812, declared by the United States on Great Britain under President James Madison on 18 June 1812.
The war was primarily caused by the British Navy's boarding of American ships to forcibly enlist any sailors of British origin and its attempts to prevent the United States from trading with France.
The United States planned to take over Upper Canada (the basis of modern-day Ontario) and Lower Canada (the basis of modern-day Québec) in a single mass attack. The invasion was to occur at four strategic locations: across from Detroit, in the Niagara area, at Kingston, and south of Montréal. If they succeeded, they would isolate and then capture the stronghold of Québec City, thereby cutting off any further British troop movement up the St Lawrence River and into the Great Lakes.
There were wins and losses on both sides during the two years that the war lasted, with no clear victory for either of the warring parties (the Treaty of Ghent signed on 24 December 1814 maintained the status quo). The British colonies, however, remained independent of the United States and their inhabitants would continue to forge what would become some fifty years later the new Canadian nation.
