Mexican American War Research Paper

The Mexican American War started in 1846 because of Mexican resentment caused by the 1836 loss of Texas and the American’s desire for Mexico’s more northern territory. “On September 9, 1847 after two years of fighting, the Mexican American war essentially ended when the American Army captured Mexico City after the Battle of Chapultepec”( 6). The Treaty of Guadalupe Hidalgo ended the war. United States leaders then acted morally superior in their negotiations of the treaty 1. During negotiations, United States officials viewed the “forcible incorporations” (1) of almost one half of Mexico’s land as an “event foreordained by providence and Manifest Destiny” (1). The Treaty of Guadalupe Hidalgo is written evidence of the biggest land acquisition in American history.

INTRODUCTION Throughout the 1840s and 1850s a major war happened called the Mexican American War which drastically changed the U.S. and Mexico and lead to the Treaty of Guadalupe Hidalgo to be signed and which established the Rio Grande and not the Nueces River as the U.S Border. This also lead to the U.S. annexation of Texas and lead to the Mexico agreeing to sell California and the rest of the territory for 15 million. So you 're probably wondering why the war was fought but you 'll find that out later.

The causes of the Mexican-American war were the Annexation of Texas, Land Disputes between Mexico and the United States of America and President Polk’s Greed. The country of Mexico was upset and angry with the United States of America because they took the state of Texas away from them. The two continued to dispute over Southern Texas and the land between the rivers Rio Grande and Nueces. President Polk later sent a messenger to offer thirty-million dollars for the SouthWest. Mexico declined the offer and President Polk declared war on Mexico.

The United States war with Mexico continues to be a divisive topic among many people because of its background. The Mexican-American war was a fight between Mexico and America for land. America’s belief at the time was Manifest Destiny, which meant that they believed that America should extend from the Atlantic Ocean to the Pacific ocean. In the end, America benefited from the war and got the land. The United States expanded its size, achieving their dream of Manifest Destiny. Although the United States war against Mexico resulted in the gaining of America’s most valuable land, the war itself wasn’t legitimate because of the revolution in Texas, motivation for superiority, and the U.S. government’s actions.

More so because of the Texas revolution that happened years earlier. The border of Texas had not been originally confirmed or settled. The U.S then as written, journeyed out to claim the land there selves The Mexican war began at the time and year when James Polk was elected as president. Year 1845, James Polk offered a proposition to the Mexican government.

As stated before, the US was justified in going to war with Mexico because of three reasons, Americans were killed, Texas was already annexed, and Manifest Destiny allows it. The United states had many superb reasons for going to war with Mexico. This essay is significant because it helps explain the United States’ choice to go to war with

When Mexico gained its independence from Spain in 1821, a string of ruthless dictators and weak presidents made Mexico an easy target for its powerful neighbor, the United States. The US swooped in to expand its territory and its popular institution of slavery. By doing so, the US started a war with Mexico that was justified for illegitimate reasons. The Mexican-American War was not justified because the US took Mexico’s land for the expansion of slavery, and justified their taking advantage of Mexico when it was politically weak by hiding behind Manifest Destiny.

Manifest destiny also affected the relationship with Mexico. Several factors led to the Mexican- American War in 1846. The factors were that the U.S citizens were moving into California and Mexico. Since there were many revolutions happening in Mexico throughout this time period the Mexican government was not able to protect the U.S citizens in this region. Another factor was that Mexico was upset that Texas declared independence from them and then the U. S annexed Texas in 1845.

The Mexican-American war altered the United States environmentally, culturally and politically. First, on February 2, 1848, Mexico signed the Treaty of Guadalupe Hidalgo two years post the beginning of the war. The treaty not only achieved President Polk’s goal to achieve California from Mexico but also granted the U.S. over 500,000 square miles of new territory. The new land caused approximately 90,000 spanish speaking, mostly Catholic Mexicans under American jurisdiction. Second, Nativism, a rising anti-catholic and anti-immigrant deemed the Mexicans inferior.

Americans were outraged over the border dispute at the Nueces and the Rio Grande rivers, and Mexicans were irate with America’s annexation of Texas. President James K. Polk availed in the atmosphere of animosity, hurrying to place troops on conflicted land. On May 9, 1846, he found his cause for war. Mexican and American troops had engaged in combat on April 24, which led American blood spilt on contended soil. However, through all their fighting spirit, the Americans faithfully ignored their own mistreatment of the Mexicans.

This war happened mainly because the U.S. wanted to expand to the Pacific Ocean to fulfill their Manifest Destiny, trying to take away Mexico’s land. Mexico refused to to give land to the U.S. The big question is whether the U.S. was justified in fighting Mexico in the Mexican-American War. The United States was justified in going to war with Mexico because Manifest Destiny, too much Mexican interference, and Texas was invaded. One reason the Mexican War was justified was Manifest Destiny. In Document A, John O’Sullivan writes: “Texas is now ours...Let their reception into the “family be frank, kindly, and cheerful….”

War is going on all the time and whether the causes are appropriate or not is debatable. Many times war is the last result, but for the US, in this case, armed conflict was the only option. On April 25th, 1846 a massive Mexican Army attacked Captain Seth Thornton and his US Army north of the Rio Grande. Many were overtaken by fear, of what was to come. War. However, the question still remains to this day, was the US justified in going to war with Mexico? Justified means to have good reason or be right about a decision. Did the US have good reason to start a war with Mexico? As far as the US-Mexican War is concerned the Americans did have appropriate causes for war. They 're acceptable reasons were Manifest Destiny, wanting to protect Texas, and the Mexicans ' strike on America because of a border dispute.

Thirdly, a second reason the Mexican War was not justified because US soldiers were in a disputed area. According to Jesus Velasco Marquez from “A Mexican Viewpoint on the War With the United States,” he states that “From Mexico’s point of view, the annexation of Texas to the United States was inadmissible for both legal and security reasons.” As well as, “The American government acted like a bandit who came upon a

The big debate across the growing United States was the debate of slavery and which states would come in as free or slavery states. The Mexican-American War was a major turning point in this debate because it settled the debate over which states would become free or slavery states. This war lasted a little over a year and 9 months long on the border of the United States and Mexico (Texas and Mexico City). This war would helped settle many disputes, but the main debate it would settle would be the huge slavery debate. The Mexican-American War helped the United States gain new territory is the south-western part of the United States.

There have been many events that shaped the history on Mexico. The majority of the times it always comes at the expense of a human life. The Mexican American War in 1846 not only changed Mexico geographically but also let to many casualties. The drug cartels that are in search of power and land also take the lives of many in order for them to obtain their power. These are a couple of events that have shaped the history if Mexico, but in my opinion on of the most important one is the Cristeros War. This was a war between the Catholic Church and Mexican government. I wanted to be more informed about how large groups of religious people were able to defeat a Mexican military that was led by the President.
