What was one effect of US expansion in the 1890s?

A significant push toward the west coast of North America began in the 1810s. It was intensified by the belief in manifest destiny, federally issued Indian removal acts, and economic promise. Pioneers traveled to Oregon and California using a network of trails leading west. In 1893 historian Frederick Jackson Turner declared the frontier closed, citing the 1890 census as evidence, and with that, the period of westward expansion ended.

In the nineteenth century, the United States expanded its territory westward at a dramatic pace, leading to conflict, national growth, and ongoing cultural exchange within a transformed continent.

Background

The expansion of the United States into the territory west of the Mississippi River began with the Louisiana Purchase in 1803. President Thomas Jefferson nearly doubled the size of the nation by negotiating a price of $15 million to purchase 828,800 square miles from France, including all or part of 14 current states. In 1804, Jefferson sent an expedition led by Meriwether Lewis and William Clark to explore the area. The three-year expedition produced new understanding of the geography and resources of the western part of the continent. In the 1830s and 1840s, “manifest destiny”, the idea that the United States was destined to expand across the entire continent, was used to promote further territorial expansion. And the nation expanded quickly:

• In 1845 the United States annexed Texas;
• In 1846 the Oregon Treaty ended British claims to Oregon Territory;
• In 1848, following the Mexican-American War, Mexico ceded much of the Southwest to the United States;
• In 1853 the United States bought an additional tract of land from Mexico.

States joined the Union at a relatively fast pace: California became a state in 1850 and Oregon in 1859, Nevada in 1864, Nebraska in 1867, Colorado in 1876, South and North Dakota, Montana, and Washington in 1889, Wyoming and Idaho in 1890, and Utah in 1896. As new towns like Denver and Phoenix sprang up in these new states, established towns and cities grew to accommodate the new industries and new populations that westward expansion brought with it.

A number of factors fueled migration west. Trappers, settlers, and miners headed West from the eastern United States prior to the Civil War. The Homestead Act, passed in 1862, allowed settlers to claim 160 acres of land for free. Another important factor was completion of the first transcontinental railroad in 1869; the railroad led to much more rapid western migration and also facilitated economic development.

In looking at the history of the American West, it is important to keep in mind the myths that arose around the settling of the West in the second half of the nineteenth century. The influential historian Frederick Jackson Turner described a uniquely American personality forged by the experience of taming the wilderness and critical to the success and growth of the United States. That view of the West as a frontier where heroic white settlers and cowboys struggled to bring civilization to a savage land framed popular and scholarly thinking for years to come.

More recently, however, historians have questioned the notion of the frontier. Instead, they have argued that the nineteenth-century West was a crossroads of cultures. The trans-Mississippi West was home to countless Native American communities. The lifeways of the Native American groups varied considerably. Some with nomadic lifestyles required large amounts of rangeland to maintain their families; other groups lived in settled communities, where they farmed and raised livestock brought to the West by the Spanish. The cultural diversity was heightened by the addition of tens of thousands of Native Americans forced west from the eastern areas of the United States.

Spain ruled what is today the southwestern United States between 1598 and 1821; it used land grants to promote settlement and protect this remote region of its empire. Spanish policy was to give settlers free land owned by the government. The Republic of Mexico followed many of the same policies when it governed the Southwest between 1821 and 1848.

Thus, when white settlers began pouring into the West, they were entering a region in which indigenous peoples and Spanish settlers had been living for hundreds of years. Nor was east the only direction from which settlers came into the American West.

African Americans came from the southeast, Spanish settlers came from Mexico in the south, and workers came from the west, across the Pacific from China.

The hope for economic advancement that brought white settlers to the West also brought workers from Asia. Chinese immigrants worked in mining, ran small businesses, and helped build railroads across the West; however, they were often met with hostility and violent attacks when they attempted to settle into communities.

Expansion in the American West continues today, as its population centers continue to expand into even the most remote areas of the region. Cultural encounters also continue to have an impact on everyday life in the United States, and may prove to be among the most important legacies of the great era of westward expansion.

Additional Resources

Manifest Destiny, a phrase coined in 1845, is the idea that the United States is destined—by God, its advocates believed—to expand its dominion and spread democracy and capitalism across the entire North American continent. The philosophy drove 19th-century U.S. territorial expansion and was used to justify the forced removal of Native Americans and other groups from their homes. The rapid expansion of the United States intensified the issue of slavery as new states were added to the Union, leading to the outbreak of the Civil War.

Louisiana Purchase

Thanks to a high birth rate and brisk immigration, the U.S. population exploded in the first half of the 19th century, from around 5 million people in 1800 to more than 23 million by 1850.

Such rapid growth—as well as two economic depressions in 1819 and 1839—would drive millions of Americans westward in search of new land and new opportunities.

President Thomas Jefferson kicked off the country’s westward expansion in 1803 with the Louisiana Purchase, which at some 828,000 square miles nearly doubled the size of the United States and stretched from the Mississippi River to the Rocky Mountains. In addition to sponsoring the western expedition of Lewis and Clark of 1805-07, Jefferson also set his sights on Spanish Florida, a process that was finally concluded in 1819 under President James Monroe.

But critics of that treaty faulted Monroe and his secretary of state, John Quincy Adams, for yielding to Spain what they considered legitimate claims on Texas, where many Americans continued to settle.

In 1823, Monroe invoked Manifest Destiny when he spoke before Congress to warn European nations not to interfere with America’s Westward expansion, threatening that any attempt by Europeans to colonize the “American continents” would be seen as an act of war. This policy of an American sphere of influence and of non-intervention in European affairs became known as the “Monroe Doctrine.” After 1870, it would be used as a rationale for U.S. intervention in Latin America.

Texas Independence

Cries for the “re-annexation” of Texas increased after Mexico, having won its independence from Spain, passed a law suspending U.S. immigration into Texas in 1830.

Nonetheless, there were still more Anglo settlers in Texas than Hispanic ones, and in 1836, after Texas won its own independence, its new leaders sought to join the United States. The administrations of both Andrew Jackson and Martin Van Buren resisted such calls, fearing both war with Mexico and opposition from Americans who believed calls for annexation were linked with the desire to expand slavery in the Southwest.

But John Tyler, who won the presidency in 1840, was determined to proceed with the annexation. An agreement concluded in April 1844 made Texas eligible for admission as a U.S. territory, and possibly later as one or more states.

Despite opposition to this agreement in Congress, the pro-annexation candidate James K. Polk won the 1844 election, and Tyler was able to push the bill through and sign it before he left office.

The Coining of 'Manifest Destiny'

By the time Texas was admitted to the Union as a state in December 1845, the idea that the United States must inevitably expand westward all the way to the Pacific Ocean had taken firm hold among people from different regions, classes and political persuasions.

The phrase “Manifest Destiny,” which emerged as the best-known expression of this mindset, first appeared in an editorial published in the July-August 1845 issue of The Democratic Review.

In it, the writer criticized the opposition that still lingered against the annexation of Texas, urging national unity on behalf of “the fulfillment of our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions.”

As the phrase also appeared in a nearly identical context in a July 1845 article in the New York Morning News, its originator is believed to be John O’Sullivan, the editor of both the Democratic Review and the Morning News at the time. That December, another Morning News article mentioned “manifest destiny” in reference to the Oregon Territory, another new frontier over which the United States was eager to assert its dominion.

Oregon Territory

An 1842 treaty between Great Britain and the United States partially resolved the question of where to draw the Canadian border, but left open the question of the Oregon Territory, which stretched from the Pacific Coast to the Rocky Mountains over an area including what is now Oregon, Idaho, Washington State and most of British Columbia.

Polk, an ardent proponent of Manifest Destiny, had won election with the slogan “54˚ 40’ or fight!” (a reference to the potential northern boundary of Oregon as latitude 54˚ 40’) and called U.S. claims to Oregon “clear and unquestionable” in his inaugural address.

But as president, Polk wanted to get the issue resolved so the United States could move on to acquiring California from Mexico. In mid-1846, his administration agreed to a compromise whereby Oregon would be split along the 49th parallel, narrowly avoiding a crisis with Britain.

Impact of Manifest Destiny: The Civil War, Native American Wars

By the time the Oregon question was settled, the United States had entered into all-out war with Mexico, driven by the spirit of Manifest Destiny and territorial expansion.

The Treaty of Guadalupe Hidalgo, which ended the Mexican-American War in 1848, added an additional 525,000 square miles of U.S. territory, including all or parts of what is now California, Arizona, Colorado, New Mexico, Nevada, Utah and Wyoming.

Despite the lofty idealism of Manifest Destiny, the rapid territorial expansion over the first half of the 19th century resulted not only in war with Mexico, but in the dislocation and brutal mistreatment of Native American, Hispanic and other non-European occupants of the territories now being occupied by the United States.

U.S. expansion also fueled the growing debate over slavery, by raising the pressing question of whether new states being admitted to the Union would allow slavery or not—a conflict that would eventually lead to the Civil War.
