Territorial expansion was one of the defining characteristics of early American history, and remained a major component of American life from the founding of the Jamestown and Plymouth colonies in the early 17th century until the director of the U.S. Census Bureau announced the frontier had closed in 1890. From 1791 to 1900, thirty-one new states joined the Union, as record numbers of Americans migrated annually and the United States government pursued an aggressive policy of territorial acquisition.

In 1845, the newspaper editor and writer John Louis O’Sullivan coined the term “manifest destiny” to describe the prevailing ideology that legitimized American expansion and encouraged so many Americans to move across the country. O’Sullivan argued that it was the nation’s “manifest destiny to overspread the continent” and spread democracy. He argued that westward expansion was ordained by god and, as a result, the inescapable destiny of the American people. Many Americans wholeheartedly bought into this sentiment, as millions of Americans heeded the words of John Babsone Lane Soule to “Go West, young man.” Americans migrated West to seek their fortunes, but not all Americans would find success in the West, and many Americans who migrated across the country would quickly realize that there was a large gap between the reality of life in the West and the burgeoning mythology that was developing about the West in American culture.

Manifest Destiny

John Louis O’Sullivan, a popular editor and columnist, articulated the long-standing American belief in the God-given mission of the United States to lead the world in the peaceful transition to democracy. In a little-read essay printed in The United States Magazine and Democratic Review, O’Sullivan outlined the importance of annexing Texas to the United States:

Why, were other reasoning wanting, in favor of now elevating this question of the reception of Texas into the Union, out of the lower region of our past party dissensions, up to its proper level of a high and broad nationality, it surely is to be found, found abundantly, in the manner in which other nations have undertaken to intrude themselves into it, between us and the proper parties to the case, in a spirit of hostile interference against us, for the avowed object of thwarting our policy and hampering our power, limiting our greatness and checking the fulfillment of our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions. John Louis O’Sullivan ((John O’Sullivan, “Annexation,” United States Magazine and Democratic Review 17, no.1 (July-August 1845), 5-10.))

O’Sullivan and many others viewed expansion as necessary to achieve America’s destiny and to protect American interests. The quasi-religious call to spread democracy coupled with the reality of thousands of settlers pressing westward. Manifest destiny was grounded in the belief that a democratic, agrarian republic would save the world.

Although called into name in 1845, manifest destiny was a widely held but vaguely defined belief that dated back to the founding of the nation. First, many Americans believed that the strength of American values and institutions justified moral claims to hemispheric leadership. Second, the lands on the North American continent west of the Mississippi River (and later into the Caribbean) were destined for American-led political and agricultural improvement. Third, God and the Constitution ordained an irrepressible destiny to accomplish redemption and democratization throughout the world. All three of these claims pushed many Americans, whether they uttered the words ‘manifest destiny’ or not, to actively seek the expansion the democracy. These beliefs and the resulting actions were often disastrous to anyone in the way of American expansion. The new religion of American democracy spread on the feet and in the wagons of those who moved west, imbued with the hope that their success would be the nation’s success.

The Young America movement, strongest among members of the Democratic Party but spanning the political spectrum, downplayed divisions over slavery and ethnicity by embracing national unity and emphasizing American exceptionalism, territorial expansion, democratic participation, and economic interdependence. Poet Ralph Waldo Emerson captured the political outlook of this new generation in a speech he delivered in 1844 entitled “The Young American”:

In every age of the world, there has been a leading nation, one of a more generous sentiment, whose eminent citizens were willing to stand for the interests of general justice and humanity, at the risk of being called, by the men of the moment, chimerical and fantastic. Which should be that nation but these States? Which should lead that movement, if not New England? Who should lead the leaders, but the Young American? Ralph Waldo Emerson

However, many Americans, including Emerson, disapproved of aggressive expansion. For opponents of manifest destiny, the lofty rhetoric of the Young Americans was nothing other than a kind of imperialism that the American Revolution was supposed to have repudiated. Many members of the Whig Party (and later the Republican Party) argued that the United States’ mission was to lead by example, not by conquest. Abraham Lincoln summed up this criticism with a fair amount of sarcasm during a speech in 1859:

He (the Young American) owns a large part of the world, by right of possessing it; and all the rest by right of wanting it, and intending to have it…Young America had “a pleasing hope — a fond desire — a longing after” territory. He has a great passion — a perfect rage — for the “new”; particularly new men for office, and the new earth mentioned in the revelations, in which, being no more sea, there must be about three times as much land as in the present. He is a great friend of humanity; and his desire for land is not selfish, but merely an impulse to extend the area of freedom. He is very anxious to fight for the liberation of enslaved nations and colonies, provided, always, they have land…As to those who have no land, and would be glad of help from any quarter, he considers they can afford to wait a few hundred years longer. In knowledge he is particularly rich. He knows all that can possibly be known; inclines to believe in spiritual trappings, and is the unquestioned inventor of “Manifest Destiny.” Abraham Lincoln

But Lincoln and other anti-expansionists would struggle to win popular opinion. The nation, fueled by the principles of manifest destiny, would continue westward. Along the way, Americans battled both native peoples and foreign nations, claiming territory to the very edges of the continent. But westward expansion did not come without a cost. It exacerbated the slavery question, pushed Americans toward civil war, and, ultimately, threatened the very mission of American democracy it was designed to aid.

Artistic propaganda like this promoted the national project of manifest destiny. Columbia, the female figure of America, leads Americans into the West and into the future by carrying the values of republicanism (as seen through her Roman garb) and progress (shown through the inclusion of technological innovations like the telegraph) and clearing native peoples and animals, seen being pushed into the darkness.

John O’Sullivan Declares America’s Manifest Destiny, 1845

John Louis O’Sullivan, a popular editor and columnist, articulated the long-standing American belief in the God-given mission of the United States to lead the world in the transition to democracy. He called this America’s “manifest destiny.” This idea motivated wars of American expansion. He explained this idea in the following essay where he advocated adding Texas to the United States.

Texas is now ours… Her star and her stripe may already be said to have taken their place in the glorious blazon of our common nationality; and the sweep of our eagle’s wing already includes within its circuit the wide extent of her fair and fertile land. She is no longer to us a mere geographical space–a certain combination of coast, plain, mountain, valley, forest and stream. She is no longer to us a mere country on the map. She comes within the dear and sacred designation of Our Country… other nations have undertaken to intrude themselves … in a spirit of hostile interference against us, for the avowed object of thwarting our policy and hampering our power, limiting our greatness and checking the fulfillment of our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions. This we have seen done by England, our old rival and enemy; and by France, strangely coupled with her against us….

The independence of Texas was complete and absolute. It was an independence, not only in fact, but of right. No obligation of duty towards Mexico tended in the least degree to restrain our right to effect the desired recovery of the fair province once our own–whatever motives of policy might have prompted a more deferential consideration of her feelings and her pride, as involved in the question. If Texas became peopled with an American population; it was by no contrivance of our government, but on the express invitation of that of Mexico herself…

California will, probably, next fall away from the loose adhesion which, in such a country as Mexico, holds a remote province in a slight equivocal kind of dependence on the metropolis. Imbecile and distracted, Mexico never can exert any real governmental authority over such a country. The impotence of the one and the distance of the other, must make the relation one of virtual independence; unless, by stunting the province of all natural growth, and forbidding that immigration which can alone develop its capabilities and fulfil the purposes of its creation, tyranny may retain a military dominion, which is no government in the, legitimate sense of the term. In the case of California this is now impossible. The Anglo-Saxon foot is already on its borders. Already the advance guard of the irresistible army of Anglo-Saxon emigration has begun to pour down upon it, armed with the plough and the rifle, and marking its trail with schools and colleges, courts and representative halls, mills and meeting-houses. A population will soon be in actual occupation of California, over which it will be idle for Mexico to dream of dominion. They will necessarily become independent. All this without agency of our government, without responsibility of our people–in the natural flow of events, the spontaneous working of principles, and the adaptation of the tendencies and wants of the human race to the elemental circumstances in the midst of which they find themselves placed. And they will have a right to independence–to self-government–to the possession of the homes conquered from the wilderness by their own labors and dangers, sufferings and sacrifices-a better and a truer right than the artificial tide of sovereignty in Mexico, a thousand miles distant, inheriting from Spain a title good only against those who have none better. Their right to independence will be the natural right of self-government belonging to any community strong enough to maintain it–distinct in position, origin and character, and free from any mutual obligations of membership of a common political body, binding it to others by the duty of loyalty and compact of public faith. This will be their title to independence; and by this title, there can be no doubt that the population now fast streaming down upon California win both assert and maintain that independence. Whether they will then attach themselves to our Union or not, is not to be predicted with any certainty. Unless the projected railroad across the continent to the Pacific be carried into effect, perhaps they may not; though even in that case, the day is not distant when the Empires of the Atlantic and Pacific would again flow together into one, as soon as their inland border should approach each other. But that great work, colossal as appears the plan on its first suggestion, cannot remain long unbuilt. Its necessity for this very purpose of binding and holding together in its iron clasp our fast-settling Pacific region with that of the Mississippi valley–the natural facility of the route–the ease with which any amount of labor for the construction can be drawn in from the overcrowded populations of Europe, to be paid in die lands made valuable by the progress of the work itself–and its immense utility to the commerce of the world with the whole eastern Asia, alone almost sufficient for the support of such a road–these coast of considerations give assurance that the day cannot be distant which shall witness the conveyance of the representatives from Oregon and California to Washington within less time than a few years ago was devoted to a similar journey by those from Ohio; while the magnetic telegraph will enable the editors of the “San Francisco Union,” the “Astoria Evening Post,” or the “Nootka Morning News,” to set up in type the first half of the President’s Inaugural before the echoes of the latter half shall have died away beneath the lofty porch of the Capitol, as spoken from his lips.

Away, then, with all idle French talk of balances of power on the American Continent. There is no growth in Spanish America! Whatever progress of population there may be in the British Canadas, is only for their own early severance of their present colonial relation to the little island three thousand miles across the Atlantic; soon to be followed by Annexation, and destined to swell the still accumulating momentum of our progress. And whosoever may hold the balance, though they should cast into the opposite scale all the bayonets and cannon, not only of France and England, but of Europe entire, how would it kick the beam against the simple, solid weight of the two hundred and fifty, or three hundred millions–and American millions–destined to gather beneath the flutter of the stripes and stars, in the fast hastening year of the Lord 1945!

Summary

Although for many Americans, the era of “Manifest Destiny” represented a truly exciting and prosperous time, for a variety of diverse groups of Americans westward expansion represented a challenge to American democratic ideals, and posed new questions about the role of Native-Americans in American society and the expansion of slavery that would challenge Americans for decades. Westward expansion also had enormous ramifications on the environment of North America, including the extinction or near extinction of several types of native western wildlife, such as the American buffalo, and the transformation of the native ecologies and environments west of the Mississippi River. Finally, Westward expansion impacted the politics and social and cultural norms of the nation, and by the middle of the 19th century the population of the United States living west of the Mississippi nearly rivaled the population of the country living east of the Mississippi. Based on the simple fact that nearly no American citizens lived west of the Appalachian Mountain range, let alone the Mississippi River, in the 18th century, westward expansion had clearly altered the demographics and territorial boundaries of the country. And the ideology of manifest destiny was largely responsible for justifying and legitimizing that expansion in the minds of the American people.
