We have all heard of the term Manifest Destiny. Many of us had some rudimentary education about the American expansion to the West and the great cultural legacy that the West left on the American image. Interestingly, the West we imagine today could have very easily been the Mexican state of Baja California, or the vast Canadian province of British Columbia. Those who sought to expand the United States during the early 19th century clearly had no mental image of how expansive the Republic would become . Like children, the early United States and her politicians held grandiose dreams of continental conquest. Unsurprisingly, the objects of this desire were our friendly neighbors, Mexico and Canada.
As many are already aware, Mexico was a clear target of U.S. land interests. Though referred to as a sister republic by some, no American statesman denied that Mexico was in the way of the Jeffersonian ideal of the Empire of Liberty. The Mexican Republic maintained flimsy authority over her northern territories, unable to suppress local Native American hostilities, nor send enough settlers in to make a profit.
Through interpreting what was then thought of as divine will, and egging Mexican forces into taking the first shot, the U.S. took the Northern Mexican territories as the spoils of the Mexican American war. What is less known, is that the U.S. briefly considered the annexation of the entirety of Mexico. The movement, known as the All-Mexico movement, was popularized after the American invasion of Mexico proper. With U.S. forces successful in the field, American politicians became bold enough to suggest that the United States could incorporate the entirety of Mexico. Why not? It was said that some Mexicans felt more secure under the leadership of General Zachary Taylor than his Mexican counterparts, and Kearney seemed to be liberating Mexicans in the northern provinces from religious conservatism and political corruption. The answer to that question came in two parts.. As one of manifest destiny’s premises was to display the civic virtue of the United States, forcing American democracy on another nation-state was seen as abhorrent. Perhaps the more notable argument was John C. Calhoun’s “Our’s, sir, is the government of the white race.”
Evident to us of the 21st century, the U.S. did not annex Mexico. Though one could attribute this result to the consensus of white supremacy in the U.S. government, it is also notable that Mexico was the land of continuing dissent. In fact, Mexican factions quarreled amongst themselves, even as U.S. troops marched closer and closer to Mexico City. In this aspect, we can see the practicality in the U.S. government’s position to not annex Mexico, as it would simply put the burden of political instability on the U.S.
American desire for the occupation of Canada was almost as old as the U.S. herself. Unlike Mexico however, Canada’s image in the eyes of the United States was not one that required “civilization.” Of course, this could be due to the common cultural heritage that Canada and the United States derived from Britain, but the focal point on U.S. policy seemed to always link back to security. Some historians argue that the insecurity of the Northern borders of Colonial North America induced colonials to believe that Canada was a strategically critical position. The Revolutionary War saw the coming of American invitations to not only the Canadians, but Floridans, and West Indians to join the cause. Canada always prickled the imagination of our founding fathers as a security liability. Much like the way that Britain viewed Ireland during the rise of Napoleon, Americans viewed Canada as a potential staging point for a British Invasion and military tactics. This proved to be true after the War of American Independence as Canada became an important base of operations for British harassment of American frontiersman.
In the early years of the United States, Canada was viewed more as an object of hate that the Americans could lash out against to protest British actions. The most famous incident of this would be the War of 1812, where the American armed forces took the liberty of striking Canada while the bulk of the British forces were occupied with Napoleon’s France. Many American statesmen were under the impression that a successful invasion of Canada would shock the British government enough to force it into reckoning with American rights and neutrality. Even so, William Hull, the American general in charge of the invasion of Canada (and also famous for losing fort Detroit without firing a single shot) proclaimed that the Canadians would be liberated from British sovereignty. Such rhetoric was one of the foundations of Manifest Destiny. The premise goes back to Thomas Jefferson’s concept of an Empire of Liberty. As many Americans know, the invasion was a failure, and to some extent, an embarrassment to the American forces. Afterwards, military threats directed at Canada came not in the hands of the American government, but private entities that had qualm with British policies. A famous example would be the Fenian Brotherhood’s actions in Canada to pressure Britain’s withdrawal from Ireland in the late 19th century. The question of Canada’s involvement rose again when the British and American governments disputed over the ownership of the Oregon territory. Stretching as far north into British Columbia and far south to Oregon, the Oregon territory had been jointly occupied by the U.S. and the U.K. Becoming increasingly aggressive, the U.S. statesmen urged then President Polk to claim all of the territory. Though tempted, the dark horse president settled for the 49th parallel which divides Washington and British Columbia today.
