Mexican American Conquest

The Mexican American War was a very controversial event. The Americans believed in their “Manifest Destiny” which prompted them to annex the territory of Texas which, in turn, initiated the war on April 25, 1846. Texas was annexed to the Union as a slave state on December 29, 1845. This upset all of the Free states along with the Mexicans but the Southerners were in favor of the war because it gave them more strength when fighting for slavery. While there were many different beliefs about the Mexican-American War throughout the United States, these beliefs generally were the same within a region.

The Mexican War was viewed as one of the most controversial wars in United States history. Originating from the annexation of Texas, or the lack thereof in Mexico’s eyes, the final spark to cause the war was an incident between soldiers of both countries in disputed land. Both Mexico and the US claimed to have been provoked by the other, and that they were only protecting their country. Many US citizens argued the war, as it appeared President Polk was using it for reasons other than self defense. By going to war with Mexico, the US faced the possibility of gaining much more of Mexico’s land and extending slavery in the country. The United States' decision to go to war with Mexico was based on a desire to extend slavery, to gain land they had

The Treaty of Guadalupe Hidalgo in 1948 would have lasting negative effects on Mexican Americans. The Treaty was signed after America had won the Mexican American war. America gained possession of the southwest states that had been part of Mexico for the price of around eighteen million dollars. In Article IX of the Treaty, it states that the Mexicans "shall be maintained and protected in the free enjoyment of their liberty and property, and secured in the free exercise of their religion without restriction"(Vargas 139). And as Rachel Rivera points out Article VII promised the Mexicans the right to keep their land which previously belonged to Mexico. However, the Treaty would not grant the

The aftermath of the Mexican American warManifest Destiney, the annexation of Texas, and the actions of President John Polk are all factors leading up to the Mexican-american war. It is known that the annexation of Texas was what pushed Mexico leaders over the edge. In 1836 Texas gained independence from Mexico, after becoming an American State the relationship between Mexico and the U.S quickly came to an end. Polk not only had his eyes on Texas but also on California and New Mexico. Polk won the support of the american people by declaring he would complete Americas Manifest Destiny, to reach the West coast. Mexico denied Polk’s offer to buy these lands, leading America to send troops onto disputed territory. April 25, 1846 Mexican troops killed american soldiers on the disputed land, marking the beginning of the war, this was the battle of Palo Alto. The Mexican-American war had a major impact on both Mexico and U.S history. This essay will discuss the political, social, and economical effects between Mexico and the U.S after the Mexican American war.

Polk had said that Mexico were planning on an invasion and declared war on Mexico. This didn’t show that we show not be afraid or fear military ambition. It showed how selfish man can be just to gain more territory because they believed that it was their right to expand the country. Mexico only wanted what was theirs after claiming independence from Spain, and not have it taken away. Texas was under Mexico law, and Mexico banned slavery. Many Americans settlers did live in Texas at the time and knew it was against Mexico’s law but still had slaves anyways. The war lasted for three years, but soon Mexico decided to sign a peace treaty that gave territories to America. America paid Mexico 15 billion for lands that are known today as California, Arizona, Colorado, Nevada, New Mexico, Utah and

The Mexican-American War was driven by the idea of "Manifest Destiny" (Which is the belief that America had a God-given right to expand the country's borders from sea to sea) This belief would eventually cause a great deal of suffering for many Mexicans, Native Americans and United States citizens. Following the earlier Texas War of Independence from Mexico, tensions between the two largest independent nations on the North American continent grew as Texas eventually became a U.S. state. Disputes over the border lines sparked military confrontation, helped by the fact that President Polk eagerly sought a war in order to seize large tracts of land from Mexico.

The election of 1844 pitted James Polk, a Democrat expansionist, against Whig leader Henry Clay. One of Polk’s slogan was called, 54°40 or Flight, which supported pushing foreign troops past that latitude and out of the Oregon Territory. Fundamentally, that was jointly administered by the United States and British in Canada. Polk’s supporters also wanted the immediate annexation of Texas as well as expansion into the Mexican-claimed territories of New Mexico, Arizona, and California. Clay, too, favored expansion, but at a slower rate. He also hoped to avoid war by negotiating with Mexico and Britain for the land America wanted. The election was close, but in the end Polk won. In the last days of his administration, President Tyler proposed the annexation of Texas, arguing that Polk’s victory amounted to a mandate for annexation. The annexation vote was passed, the United States annexed Texas, and Mexico broke off diplomatic relations. Under these circumstances, war with Mexico seemed likely.

James K. Polk was the 11th presidents of the United states of America. His name is perhaps most closely associated with Manifest Destiny, because a year before he became the president, the Manifest destiny started the embody the governing philosophy of the Polk administration and its ardently expansionist aims. Polk’s campaigning methods is the leading cause to his victory of becoming the president of America. He campaigned on an expansionist platform, and vowed to not agree with the British on the dispute over the Oregon Territory's northern border. After Polk took office, the tension with Mexico over the annex of Texas continued to grow. In May 1846, Polk got his cabinet to approve of him to send a message of war against Mexico to Congress. In May 1847, president Polk had Nicholas P. Trist, the chief clerk in the state department, to Mexico with Gen. In spite of Polk's wish, Trist signed the Treaty of Guadalupe Hidalgo in early February 1848. This was the Treaty that ended the Mexican American War. Polk still was unhappy with the land he had just ceased- but polk had to settle with what the Treaty of Guadalupe Hidalgo had got him: California, Nevada, Utah, most of New Mexico and Arizona, and the disputed

The United States wanted to expand its territory toward the West and the Southwest during the Market Revolution in search for raw materials. After gaining its independence from Spain in 1821, Mexico was left “destitute, reducing its ability to supply the establecimientos as before.” Aside from that, Native groups such as the Apache and the Comanche returned to raid its supply. They continued to raid Mexico, especially Texas. Eventually, the Native groups reached the outskirts of Mexico City. To create a buffer zone between Mexico and the Natives, the Mexican government opened its border in Texas and welcomed new settlers. Most of these settlers were Anglo-American. By the end of the 1820s, “Anglo-American outnumbered Mexicans in Texas 12,000 to 5,000.” The Anglo-American brought with them cash crops that helped flourished the economy of Texas.

that President Polk had no right to do what he did. It is said that

Polk would not have the same peaceful negotiations with Mexico over disputed land as he did with Great Britain. Though General Santa Anna signed a treaty recognizing Texas' independence in 1836, both parties would dispute ownership of the land between the Nueces River and the Rio Grande until 1848. When the United States annexed Texas and stood behind its claim over the disputed land, the Mexican government became infuriated with America and broke off all diplomatic relations and started to prepare for war. The Mexican-American War would ultimately start over disputed land in Texas. It would turn into so much more. Polk's final goal was to gain control of all the Mexican territories to the west of Texas. Polk continued to try to resolve this problem peacefully through a treaty with Mexico, but they refused to hold any diplomatic talks with Polk's representatives. This forced Polk to have his military occupy the disputed land all the way to the Rio Grande. General Taylor informed Polk that soon after arrival to the Rio Grande the Mexican army attacked him and

The Mexican War of 1846-1848 was one of major importance to U.S. history, but has since fallen into annals of obscurity. It was the nation’s first war fought on foreign soil: a war that advocated the concept of “manifest destiny”, the United States God-given right to claim territory for the establishment of a free democratic society (Stevenson 2009). Even though many historians claim the war was forced on Mexico by slaveholders greedy for new territory, President John Polk viewed the war as an opportunity to defend the annexation of Texas, establish the Rio Grande as its border, and to acquire the Mexican territories of California and New Mexico (Stevenson 2009).

In 1845 Texas was annexed as a state, however disputes between America and Mexico remained concerning where the border would be located. President Polk at the time had no choice but to send troops due south to defend Texas and the Thornton affair, won by the Mexicans, would force congress to declare war on Mexico.

It is worth noting here that the Americans were concerned about appearances, and that they did their best to provoke Mexico into a war, without having to bear the responsibility of actually starting the war. In his Personal Memoirs, Grant explained the mission of the U.S. Army in south Texas, "We were sent to provoke a fight, but it was essential that Mexico should commence it." The plan worked. The U.S. annexed Texas in February of 1846, and Polk immediately ordered Taylor to proceed to the Rio Grande. One of Taylor's patrols skirmished with a Mexican detachment and lost over twenty soldiers, including eleven dead, five wounded, and several captured. Polk immediately called for war. In his bellicose message to the U.S. Congress, the President announced that, "American blood had been shed upon American soil." He got his declaration of war.

The Mexican-American war determined the destiny of the United States of America, it determined whether or not it would become a world power and it established the size of the United States of America. Perhaps the war was inevitable due to the idea of Manifest Destiny - Americans thought they had the divine right to extend their territory. The Mexican-American War started mainly because of the annexation of the Republic of Texas (established in 1836 after breaking away from Mexico). The United States and Mexico still had conflicts on what the borders of Texas was, the United States claimed that the Texas border with Mexico was the Rio Grande, but the Mexicans said that it was the Nueces River, so the land in between were disputed and
