 Manifest Destiny In 1845, John O'Sullivan asserted the right of America's manifest destiny to possess the whole continent for the great experiment of liberty. Manifest destiny is the phrase most associated with America's conquest of the West. In historical context, it referred to the belief that Americans were destined by God to govern the entire continent, including Canada, Mexico, and beyond. At the country's founding, Alexander Hamilton wanted to acquire Louisiana to, secure to the United States, the key to the Western country, and regretted that the preparation of an adequate military force does not advance more rapidly. Even Thomas Jefferson wanted to send troops to the frontier to add to the Empire of Liberty an extensive and fertile country. As president, Jefferson purchased the Louisiana Territory, despite his conviction that he was violating the Constitution. By adding nearly one million square miles to the nation's Western boundary, the Louisiana Purchase revealed the first characteristic of Empire, expansionism. The U.S. similarly purchased Oregon in 1846 and Alaska in 1867, reflecting the imperial characteristic of centralization. In Alaska's century as a territory, its governance was decided by politicians 3700 miles away. That's 500 miles further than London is from Boston. Western expansion was also territorial and coercive. America's annexation of Texas instigated the Mexican War, a boundary dispute that cost upwards of 38,000 lives, but resulted in the acquisition of territory far beyond the Texas borders. The war also helped consolidate a national standing army, which provided the impetus for aggressive diplomacy toward Indians. Early Western settlers frequently traded peacefully with Indians, but as the U.S. Army took over Indian relations, frontier warfare intensified. Manifest destiny is not confined to American expansion. The core concept is the belief that a nation is morally obligated to forcefully spread its superior culture, and this has been repackaged to justify imperial warfare throughout history. In theocratic societies, these conflicts took the form of holy wars, such as Crusades and Jihad. In the U.S., Manifest Destiny has traditionally expressed political ideals, such as Jefferson's dream of an empire of liberty and Woodrow Wilson's promise to keep the world safe for democracy. In 1899, British writer Rudyard Kipling characterized Manifest Destiny as the white man's burden. This was his title for a poem intended to encourage Americans to join European empires in spreading Western civilization across the ocean. Kipling published the poem in the aftermath of a conflict that marked the beginning of America's overseas empire, the Spanish American War.
