There were several immediate stated causes for the American declaration of war: • A series of trade restrictions, the
Orders in Council (1807), were introduced by Britain to impede American trade with
France, which was at war with Britain. The US contested those restrictions as illegal under
international law. Britain had ceded the area to the United States in the
Treaty of Paris (1783) but had the long-term goal of creating a "neutral" or buffer Indian state in the area to block further American growth. The Indian nations generally followed
Tenskwatawa, the Shawnee Prophet and the brother of
Tecumseh. Since 1805, he had preached his vision of purifying his society by expelling the "Children of the Evil Spirit" (the American settlers). According to Pratt, There is ample proof that the British authorities did all in their power to hold or win the allegiance of the Indians of the Northwest with the expectation of using them as allies in the event of war. Indian allegiance could be held only by gifts, and, to an Indian, no gift was as acceptable as a lethal weapon. Guns and ammunition, tomahawks and scalping knives were dealt out with some liberality by British agents. Raiding grew more common in 1810 and 1811. Westerners in Congress found the raids intolerable and wanted them to be permanently ended.
American expansionism Historians have considered the idea that
American expansionism was one cause of the war. The American expansion into the Northwest Territory (now Ohio, Indiana, Illinois, Michigan, and Wisconsin) was being blocked by Indians, which was a major cause animating the Westerners. The American historian Walter Nugent, in his history of American expansionism, argues that expansion into the Midwest "was not the only American objective, and indeed not the immediate one area but it was an objective."
Annexation More controversial is whether an American war goal was to acquire Canadian lands, especially what is now
Western Ontario, permanently or whether it was planned to seize the area temporarily as a
bargaining chip. The American desire for
Canada has been a staple in Canadian public opinion since the 1830s and was much discussed among historians before 1940 but has since become less popular. The idea was first developed by historian
Louis M. Hacker and refined by the diplomatic specialist Julius Pratt. In 1925, Pratt argued that Western Americans were incited to war by the prospect of seizing Canada. Pratt's argument supported the belief of many Canadians, especially in Ontario, where fear of American expansionism was a major political element, and the notion still survives among Canadians. In 2010, the American historian
Alan Taylor examined the political dimension of the annexation issue as Congress debated whether to declare war in 1811 and 1812. The
Federalist Party was strongly opposed to war and to annexation, as were the Northeastern states. The majority in Congress was held by the
Democratic-Republican Party, which was split on the issue. One faction wanted the permanent expulsion of Britain and the annexation of Canada.
John Randolph of Roanoke, representing Virginia, commented, "Agrarian greed, not maritime right, urges this war. We have heard but one word - like the whippoorwill's one monotonous tone: Canada! Canada! Canada!" The other faction, based in the South, said that acquiring new territory in the North would give it too much power and so opposed the incorporation of Canada since its Catholic population was viewed as "unfit by faith, language and illiteracy for republican citizenship." The Senate held a series of debates and twice voted on proposals that explicitly endorsed annexation, neither of which passed. However, the second failed only because of a proviso stating that Canada could be returned to British rule after it had been annexed. War was declared with no mention of annexation, but widespread support existed among the War Hawks for it. Some Southerners supported expansionism; Tennessee Senator
Felix Grundy considered it essential to acquire Canada to preserve domestic political balance and argued that annexing Canada would maintain the free state-slave state balance, which might otherwise be ended by the acquisition of Florida and the settlement of the southern areas of the new
Louisiana Purchase. Even
James Monroe and
Henry Clay, key officials in the government, expected to gain at least
Upper Canada from a successful war. American commanders like General
William Hull and
Alexander Smyth issued proclamations to Canadians stating that the war was aimed at liberating them from British oppression and announcing an intention to annex the Canadas into the United States. Hull's proclamation also threatened them with "the horrors & calamities of war" and promised to kill out of hand any white found fighting with an Indian. Smythe wrote to his troops that when they entered Canada, "You enter a country that is to become one with the United States. You will arrive among a people who are to become your fellow-citizens." These proclamations echoed similar appeals made during the American Revolution, such as the Continental Army's
Letters to the Inhabitants of Canada.
Seizing Canada as a bargaining chip Historians now generally agree that an invasion and seizure of Canada was the main American military strategy once the war had begun. With British control of the oceans, there was no other way to fight against British interests actively. President James Madison believed that food supplies from Canada were essential to the British Overseas Empire in the
West Indies and that an American seizure would be an excellent bargaining chip at the peace conference. During the war, some Americans speculated that they might as well keep all of Canada. Thomas Jefferson, for example, was now out of power but argued that the expulsion of British interests from nearby Canada would remove a long-term threat to American republicanism. The New Zealander historian J.C.A. Stagg argued that Madison and his advisers believed that the conquest of Canada would be easy and that economic coercion would force the British to come to terms by cutting off the food supply for their highly-valuable West Indies sugar colonies. Furthermore, the possession of Canada would be a valuable bargaining chip. Stagg suggested that frontiersmen demanded the seizure of Canada not because they wanted the land, since they had plenty of it, but because the British were thought to be arming the Indians and thus blocked settlement of the West. Hickey flatly stated, "The desire to annex Canada did not bring on the war." Brown (1964) concluded, "The purpose of the Canadian expedition was to serve negotiation not to annex Canada."
Alfred Leroy Burt, a Canadian scholar but also a professor at an American university, agreed completely by noting that Foster, the British minister to Washington, also rejected the argument that annexation of Canada was a war goal. However, Foster also rejected the possibility of a declaration of war but had dinner with several of the more prominent War Hawks and so his judgement on such matters can be questioned. However, Stagg stated that "had the War 1812 been a successful military venture, the Madison administration would have been reluctant to have returned occupied Canadian territory to the enemy." Other authors concur, with one stating, "Expansion was not the only American objective, and indeed not the immediate one. But it was an objective." "The American yearning to absorb Canada was long-standing.... In 1812 it became part of a grand strategy." Another suggested, "Americans harbored '
manifest destiny' ideas of Canadian annexation throughout the Nineteenth Century." A third stated, "The [American] belief that the United States would one day annex Canada had a continuous existence from the early days of the War of Independence to the War of 1812 [and] was a factor of primary importance in bringing on the war." Another stated that "acquiring Canada would satisfy America's expansionist desires". The historian Spencer Tucker wrote, "War Hawks were eager to wage war with the British, not only to end Indian depredations in the Midwest but also to seize Canada and perhaps Spanish Florida."
Inhabitants of Ontario Most of the inhabitants of Upper Canada (now
Ontario) were Americans, but some of them were exiled
United Empire Loyalists, and most of them were recent immigrants. The Loyalists were extremely hostile to American annexation, and the other settlers seem to have been uninterested and to have remained neutral during the war. The Canadian colonies were thinly populated and only lightly defended by the British Army, and some Americans believed that the many in Upper Canada would rise and greet the American invading army as liberators. The combination implied an easy conquest. Once the war began, ex-President
Thomas Jefferson warned that the British presence posed a grave threat and pointed to "The infamous intrigues of Great Britain to destroy our government... and with the Indians to Tomahawk our women and children, prove that the cession of Canada, their fulcrum for these Machiavellian levers, must be a
sine qua non at a treaty of peace." He predicted in late 1812 that "the acquisition of Canada this year, as far as the neighborhood of Quebec, will be a mere matter of marching, and will give us the experience for the attack on Halifax, the next and final expulsion of England from the American continent." ==Violations of U.S. rights==
