But there were additional forces and political agendas at work. As the population of the original 13 Colonies grew and the U.S. economy developed, the desire and attempts to expand into new land increased. For many colonists, land represented potential income, wealth, self-sufficiency and freedom. Expansion into the western frontiers offered opportunities for self-advancement. See also Monroe Doctrine.

To understand Manifest Destiny, it's important to understand the United States' need, desire and justification to expand. The following points illustrate some of the economic, social and political pressures promoting U.S. expansion:

Recommended Reading: Seizing Destiny: The Relentless Expansion of American Territory. From Publishers Weekly: In an admirable and important addition to his distinguished oeuvre, Pulitzer Prize–winner Kluger (Ashes to Ashes, a history of the tobacco wars) focuses on the darker side of America's rapid expansion westward. He begins with European settlement of the so-called New World, explaining that Britain's successful colonization depended not so much on conquest of or friendship with the Indians, but on encouraging emigration. Kluger then fruitfully situates the American Revolution as part of the story of expansion: the Founding Fathers based their bid for independence on assertions about the expanse of American virgin earth and after the war that very land became the new country's main economic resource. Continued below...

The heart of the book, not surprisingly, covers the 19th century, lingering in detail over such well-known episodes as the Louisiana Purchase and William Seward's acquisition of Alaska. The final chapter looks at expansion in the 20th century. Kluger provocatively suggests that, compared with western European powers, the United States engaged in relatively little global colonization, because the closing of the western frontier sated America's expansionist hunger. Each chapter of this long, absorbing book is rewarding as Kluger meets the high standard set by his earlier work. Includes 10 detailed maps.

Recommended Viewing: Lewis & Clark - The Journey of the Corps of Discovery (1997) (DVD) (240 minutes) (PBS) (September 28, 2004). Review: Another reliably well-crafted, generally engrossing documentary from Ken Burns, Lewis & Clark employs the director's now-familiar approach to his subjects, from its elegant juxtaposition of period illustrations and portraits against newly filmed footage of historic sites to Burns's repertory of accomplished actors to provide gravitas for quotes from the key figures. Granted the formula has become familiar enough to allow parody, but Burns knows how to invest his historical investigations with movement and drama, making this four-hour journey a worthwhile trip. Continued below…

As narrated by Hal Holbrook, Dayton Duncan's script explicates the agenda presented by Thomas Jefferson to Meriwether Lewis and William Clark, placing it in the context of the young country's gamble in Jefferson's Louisiana Purchase, and the expedition's goals for opening the West. While preserving the heroic scale of the undertaking, Burns also finds time to delve into the politics of the venture and the disparate personalities of the two explorers; in particular, Duncan and Burns look at the career of Lewis, the presidential protégé, his moody demeanor, and his untimely death. The film also looks beyond its titular leaders to examine the personalities of their corps of soldiers, their boatmen, and the Indians they met and depended on, most notably their female Shosone guide, Sacagawea. --Sam Sutherland

 

Recommended Reading: What Hath God Wrought: The Transformation of America, 1815-1848 (Oxford History of the United States) (Hardcover: 928 pages). Review: The newest volume in the renowned Oxford History of the United States-- A brilliant portrait of an era that saw dramatic transformations in American life The Oxford History of the United States is by far the most respected multi-volume history of our nation. The series includes two Pulitzer Prize winners, two New York Times bestsellers, and winners of the Bancroft and Parkman Prizes. Now, in What Hath God Wrought, historian Daniel Walker Howe illuminates the period from the battle of New Orleans to the end of the Mexican-American War, an era when the United States expanded to the Pacific and won control over the richest part of the North American continent. Continued below…

Howe's panoramic narrative portrays revolutionary improvements in transportation and communications that accelerated the extension of the American empire. Railroads, canals, newspapers, and the telegraph dramatically lowered travel times and spurred the spread of information. These innovations prompted the emergence of mass political parties and stimulated America's economic development from an overwhelmingly rural country to a diversified economy in which commerce and industry took their place alongside agriculture. In his story, the author weaves together political and military events with social, economic, and cultural history. He examines the rise of Andrew Jackson and his Democratic party, but contends that John Quincy Adams and other Whigs--advocates of public education and economic integration, defenders of the rights of Indians, women, and African-Americans--were the true prophets of America's future. He reveals the power of religion to shape many aspects of American life during this period, including slavery and antislavery, women's rights and other reform movements, politics, education, and literature. Howe's story of American expansion -- Manifest Destiny -- culminates in the bitterly controversial but brilliantly executed war waged against Mexico to gain California and Texas for the United States. By 1848, America had been transformed. What Hath God Wrought provides a monumental narrative of this formative period in United States history.

 

Recommended Reading: The Impending Crisis, 1848-1861 (Paperback), by David M. Potter. Review: Professor Potter treats an incredibly complicated and misinterpreted time period with unparalleled objectivity and insight. Potter masterfully explains the climatic events that led to Southern secession – a greatly divided nation – and the Civil War: the social, political and ideological conflicts; culture; American expansionism, sectionalism and popular sovereignty; economic and tariff systems; and slavery. In other words, Potter places under the microscope the root causes and origins of the Civil War. He conveys the subjects in easy to understand language to edify the reader's understanding (it's not like reading some dry old history book). Delving beyond surface meanings and interpretations, this book analyzes not only the history, but the historiography of the time period as well. Continued below…

Professor Potter rejects the historian's tendency to review the period with all the benefits of hindsight. He simply traces the events, allowing the reader a step-by-step walk through time, the various views, and contemplates the interpretations of contemporaries and other historians. Potter then moves forward with his analysis. The Impending Crisis is the absolute gold-standard of historical writing… This simply is the book by which, not only other antebellum era books, but all history books should be judged.

 

Recommended Reading: Manifest Destiny and Mission in American History (Harvard University Press). Description: "Before this book first appeared in 1963, most historians wrote as if the continental expansion of the United States was inevitable. 'What is most impressive,' Henry Steele Commager and Richard Morris declared in 1956, 'is the ease, the simplicity, and seeming inevitability of the whole process.' Continued below...

The notion of 'inevitability,' however, is perhaps only a secular variation on the theme of the expansionist editor John L. O'Sullivan, who in 1845 coined one of the most famous phrases in American history when he wrote of 'our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions.' Frederick Merk rejected inevitability in favor of a more contingent interpretation of American expansionism in the 1840s. As his student Henry May later recalled, Merk 'loved to get the facts straight.'"  --From the Foreword by John Mack Faragher About the Author: Frederick Merk was Gurney Professor of American History, Harvard University.

 

Recommended Reading: Manifest Destiny: American Expansion and the Empire of Right (Critical Issue Book). From Booklist: In this concise essay, Stephanson explores the religious antecedents to America's quest to control a continent and then an empire. He interprets the two competing definitions of destiny that sprang from the Puritans' millenarian view toward the wilderness they settled (and natives they expelled). Here was the God-given chance to redeem the Christian world, and that sense of a special world-historical role and opportunity has never deserted the American national self-regard. But would that role be realized in an exemplary fashion, with America a model for liberty, or through expansionist means to create what Jefferson called "the empire of liberty"? Continued below…

The antagonism bubbles in two periods Stephanson examines closely, the 1840s and 1890s. In those times, the journalists, intellectuals, and presidents he quotes wrestled with America's purpose in fighting each decade's war, which added territory and peoples that somehow had to be reconciled with the predestined future. …A sophisticated analysis of American exceptionalism for ruminators on the country's purpose in the world.
