Manifest Destiny is the belief that Americans had the right, or even the duty, to expand westward across the North American continent from the Atlantic Ocean to the Pacific Ocean. This would spread the glorious institutions of civilization and democracy to the barbaric Native Americans. In order to accomplish this destiny, Americans did not flinch at atrocities such as provoking war with Mexico or slaughtering Indians.
Great American Desert: The "Great American Desert" was a nickname for the Great Plains. This area, the present -day Midwest, was characterized by its arid climate, a flat topography, and lack of trees. Because of these features, it was considered inhospitable and early settlers chose to cross it on the way to the Willamette Valley of Oregon rather than settling there.
"MANIFEST DESTINY": "Manifest Destiny" was the term used, throughout the 1840s, to describe Americans’ belief that they were destined by God to spread their beliefs across the continent. This sense of duty created a sense of unity among the nation and stimulated westward expansion. The term itself was coined by John O’Sullivan in an 1845 magazine article. The concept justified westward expansion in all its forms and ramifications, including the Mexican War, the persecution of the Indians, and other such ethnocentric acts.
Was it Imperialism?: American annexation of territories such as Oregon are generally not considered imperialistic because these lands were obtained by negotiation between two equal powers and the people there were not opposed to joining the Union. However, lands gained by force, such as the Mexican cession, are considered imperialistic conquests.

This treaty was defeated in the Senate, but later, in early 1845, Congress passed a joint resolution to annex Texas because of the growing popularity of annexation.
Reoccupation of Texas: After Congress voted to annex Texas, the Mexican governmen began war preparations when Texans accepted annexation. In response, Polk sent troops to occupy Texas and the disputed territory south of the Nueces River. Polk believed that the land was part of the Louisiana Purchase, and therefore it belonged to the United States.
Reannexation of Oregon: Prior to 1846, America and Great Britain had jointly occupied the Oregon Country. However, in 1844, Polk began to demand that America obtain the entire territory. In compromise, a treaty was signed in 1846 giving the United States all of Oregon south of the 49th parallel.
ELECTION OF 1844: In the election of 1844, the Whigs nominated Henry Clay. The Democrats, however, were divided between Martin Van Buren and Lewis Cass. A deadlock at the Democratic national convention resulted in the nomination of dark-horse candidate James K. Polk. The Liberty party, consisting of a small group of northern antislavery Whigs who were alienated by Clay’s indecisiveness, nominated James G. Birney. Also, large numbers of Irish immigrants turned out to vote for Polk, and he won by a small margin.

54 40’ or Fight!: In the election of 1844, Polk used "54 40’ or Fight!" as a campaign slogan, implying that the he would declare war if Britain did not give the United States all the Oregon territory up to its northern boundary, the line 54 40’ N. latitude. However, in 1846 Polk agreed to negotiate, and the two countries divided Oregon at the 49th parallel.
Slidell Mission to Mexico: Slidell was a negotiator sent to Mexico by James Polk with orders to gain Mexico’s recognition of the independence of Texas and to purchase California and New Mexico. However, he was not received by the Mexican government because the threat of military revolt left the Mexican president to weak to negotiate.
Rio Grande, Nueces River, Disputed Territory: A dispute over the southern boundary of Texas contributed to the Mexican War. Mexico claimed that the Nueces River was boundary of Texas, but Polk insisted that the Rio Grande River was the boundary line. The land between these two rivers was uninhabited, but it was a significant slice of Mexican territory.
MEXICAN WAR: The Mexican war lasted from 1846 to 1848. The main cause of the war was American desire for territory, especially Texas and California. The war took place mainly on Mexican soil. Partially because of disorganization and instability in the Mexican government, the war resulted in and American victory. The Treaty of Guadalupe Hidalgo, ending the war, made the southern boundary of Texas the Rio Grande, gave California and New Mexico to the United States, and gave $15 million to Mexico in compensation.
General Zachary Taylor: Taylor was an American major general who became a war hero during the Mexican War. His troops won important victories in northern Mexico at Matamoros, Monterrey, and Buena Vista, and his resulting popularity helped him win the presidential election in 1848.

Nicholas Trist: Trist was the chief clerk of state department and a peace officer. He was sent to Mexico by Polk to negotiate with Mexican president Herrera. They wanted Trist to convince Herrera to lower the price he was asking for California and to give Americans the right of movement over the Isthmus of Tehuantepec. In 1846, Herrera rejected the offer.
All Mexico Movement: Many Senators in Congress wanted the Treaty of Guadalupe Hidalgo to include all of Mexico, because they believed that to have control of all of Mexico would give the United States more power. However, this movement failed because the acquisition of California and her ports satisfied Polk.
MEXICAN CESSION: The Mexican Cession was the land that Mexico ceded to the United States in the Treaty of Guadelupe Hidalgo in 1848. This territory included California, New Mexico, Nevada, Arizona, Utah, Texas, and parts of Colorado and Wyoming.

OREGON FEVER: During the 1830s and 1840s, many Americans traveled to the Oregon Territory in order to start a new life. The fertile farmland available in the Willamette Valley attracted many farmers. People in the East heard exaggerated, enthusiastic reports from missionaries and pioneers, convincing them that Oregon was a "pioneer’s paradise." Many settlers traveled to Oregon overland by way of the Oregon Trail or around Cape Horn in the newly invented clipper ships. This was an important part of westward expansion.
John Jacob Astor: Astor was a wealthy New York merchant who invested in real estate. He became involved in the fur business and organized a fur trading empire from the Great Lakes to the Pacific Ocean and to China and Japan. He created the American Fur Company and established Astoria, the first major fur trading post in Oregon.

forty-niners: In 1849, 100,000 Americans, along with immigrants from Europe, Asia and South America rushed to California in search of easy riches. Competition led to violence and greed. As a result of inadequate shelter and food and the lack of medical supplies, 10,000 died the first year and few even benefited from the expedition.
Walker Tariff, 1846: The Walker tariff was created by Robert J. Walker, Polk’s secretary of the treasury, in 1846. The bill slashed all duties to the minimum necessary for revenue. It also reversed the trend of replacing certain specifics for ad value duties and dropped the minimum valuation principle. The tariff was signed July 30, 1846.
Independent Treasury System, Van Buren: The system was introduced by Martin Van Buren in 1837 and it passed through Congress in 1840.
