The Mexican War: The Causes Of The Mexican American War

War with Mexico In the year 1846 the US thought that it was their duty to God that they should expand to California, this was called Manifest Destiny. The US was a small country wanting to expand. They had rejected Texas offer to become part of the US several times, but suddenly President Polk is elected and uses Manifest Destiny as a way to get Texas and California. The US was not justified in going to war with mexico because Americans broke mexican laws set in place, they were trying to start a war to get Texas and California for themselves, and Mexico thought they were being invaded and land was stolen.

Polk still having in mind the idea about manifest destiny, thought that he had to defend Texas’ land and to do this he sent troops, but Mexico

However, because he was so stubborn, he was willing to go to war to obtain it, thinking that the Mexicans would not put up much of a fight. Polk had, at first, hoped he could gain California from Mexico the same way he had gotten Oregon from Great Britain--with what is called “eyeball diplomacy,” staring at the opponent and expecting he would blink first. This tactic obviously did not work, which angered him. Economically, the United States was not fit for a war, especially a war in a foreign country. Though the Americans did win the war, their relationship with the Mexicans became poor.

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 Mexican War was a violent and devastating event between United States and Mexico that lasted from 1846-1848. President Polk had to lie to congress, to make United States declare war on Mexico. Lincoln considered President Polk provoked as a vote-fixing device and hoped the arguments against the war would cause his reputation in the United States House of Representative. Lincoln claims President Polk misrepresented the whole thing that the Presidents Polk evidence was not true by any means. Lincoln lays out evidence that president Polk gave is either incorrect or irrelevant reasons to gain support from congress.

This egoistic mind of the US was another reason why the US was unjustified to go to war with Mexico. Polk should not have made decisions with the weak belief of “manifest destiny” which,

“Polk was a strong believer in Manifest Destiny. He believed it was God’s plan that America extend its territory all the way to the Pacific Ocean. Polk did not just want to annex Texas. He also had his eye on California” (Background Essay). A man named John L. Sullivan believed that Mexico was still too

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.

and Mexican forces had taken place in U.S. territory.” “Further, legislators were at odds over whether Polk had the right to unilaterally declare that a state of war

It was April 25, 1846. The Mexican military invaded Texas, a disputed territory. When the U.S. military came to attack, the Mexicans killed 16 Americans. This is one of the many events leading to the Mexican American War. The Mexican-American War was a major war over Mexico’s land.

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.

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

The US did not not have solid reasons to do so besides their own greed, so the US hid behind the idea of Manifest Destiny and tried to justify their actions. John O’Sullivan was the New York City journalist who coined the term Manifest Destiny. He said, “Imbecile and distracted, Mexico never can exert any real government authority over such a country…’’ (O’Sullivan, 8). O’Sullivan and the US suggested that Mexico “needed” the US to come and take over, because otherwise Mexico was going to fall apart. Although this was somewhat true, the US did not try to help Mexico through this difficult time; instead, the US took advantage of Mexico’s weakness and tried to take over completely.

The Mexican-American War changed the Unites States of America in a monumental way. This war changed The U.S.A.’s relationship with foreign powers and the economic standpoint of the nation. The Mexican- American war, and its strong ties to manifest destiny, shaped the nation in a country bordered by two seas with a chance for common folk and foreigners to have a sustainable life due to the gold rush. The war can also be accounted for the downfall leading to the Civil War over the conflict of slavery due to the land purchased in the wars treaty. Conflict between Mexico and the United States began when Texas, previously part of Mexico, became part of the United States.

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. To begin, the Texans began an unreasonable war because they didn’t follow Mexico’s laws and conditions. When Mexico started selling cheap land, they set conditions for the people moving in. The people had to convert to Catholicism, learn Spanish, become a Mexican citizen, and have no slaves. Many Americans didn’t like being told what to do, and disobeyed the rules and laws.
