The Mexican-American War: An Exercise In American Imperialism

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 United States had emerged as a modern capitalist nation, and the spirit of nationalism in the country was strong and growing” (Henderson 71). As tensions grew between the Unites States and Mexico, there was a thirst for war. The Unites States declared war with Mexico, because they owned land that Americans desired, resulting in America’s fulfillment of achieving their philosophy of “Manifest Destiny”. The blood boil of both countries caused a lot of bloodshed. The dispute lasted for a long two year battle which was for huge amounts of land. The Americans were victorious and claimed new territories from the conflict.

The United States of America has been through many wars, wars concerning many things such as land oil, pride and respect. However, when the United States went to war with Mexico, it was planned over greed. The Mexican- American war was a war provoked by the United States, in efforts to expand the coasts of the country. Mexico was a small under privileged country who had previously to the war had already lost part of their country (Texas). Needless to say this war was cut throat and violent, it was however one of the smartest business decisions America has ever made.

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 perception of history is often crafted by the information given and the information available, however, almost too often the facts accessible are warped by the viewpoints of others before they can be properly assessed. Differing outlooks thus explicate the controversial nature of historical events and why the motives and conclusions behind certain occurrences are called into question. The Mexican American war as many American historians would call it ushers a contrary tone in Mexico as their own historians would claim the “war” as United States invasion; the difference in referral is based on the different perceptions of the conflict. In the American viewpoint, the Mexican American War was driven by economic, social and political pressures to bolster United States territories, through the annexation of Texas. In the converse, it could be argued that Mexico did not declare a formal war against the United States but rather was interested in defending their country’s territorial integrity and resisting United State’s invasion. In a Mexican viewpoint then, the war was not a result of arrogance but a consequence of defending Mexican territory from United States invasion. Nonetheless the aftermath of the war produced immense repercussions, furthering American exceptionalism, slavery, and disregard for international borders prompting the inquiry of not only the unjust methods applied but the unjustified results.

     The factors that started the Mexican War lay heavily on American shoulders. Whether if the factors were created by social, political or economical needs, they have all become the center of attention for the question of being a national interest or disgrace. However, the Americans felt that they existed for “…spreading the blessings of peace.” according to Andrew Jackson. There will always be controversy between the two sides of this matter, the Americans who feel that it had to be done, to the Mexicans who felt that it was an injustice done to their nation.

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

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).

The Mexican-American war fought between 1846 and 1848 remains a topic of much contention amongst modern historians. Differing accounts and conclusions of the war are often presented and one must remain pragmatic when analysing both primary and secondary sources regarding the war. There is a clear time line of events that led to the outbreak of the war, but there is one major event, and one minor action, which directly resulted in the declarations of war on both sides of the conflict between Mexico and the United States. Most scholars agree that the annexation of the Republic of Texas by

Mexico and the United States have a rough history, as tension from the U.S. annexing Texas strained their relationship. The U.S. and Mexico couldn’t agree on a border, the U.S. believing it was the Rio Grande and Mexico believing they had all the land to the Nueces River. The remaining land in between was called undisputed land, or territory both countries shared. On May 9, 1846, Mexican soldiers shot a group of Americans patrolling the Rio Grande, inducing one of the more arguable wars, The Mexican War. In Mexico, this war is referred to as “The U.S. Invasion”, but in reality, both sides were in the wrong.

{The Mexican War’s causes date as far back as 1821, when Mexico declared independence from Spain. The Mexican government then allowed American immigrants to settle Texas to increase population. The new Texans however, did not want to be under Mexico’s control, and revolted. After several battles, the most famous being the Alamo, Texas was an independent country in 1836. However, tension between Mexico and America rose after America annexed Texas in 1844, the year President Polk, a believer in Manifest Destiny, won the election.

Dr. Henderson’s purpose for writing A Glorious Defeat: Mexico and its War with the United States is to explain the causes of Mexico going to war with the United States in 1846, and the reasons Mexico suffered severely from it. Dr. Henderson’s focus throughout the book is not solely on the military tactics, but rather on the political and diplomatic maneuvering. This approach to the book is to provide to the reader the conflict’s real significance, as to the how and why the United States and Mexico went to war. This book does not point blame at either side, but tells the war from the Mexican point of view. Furthermore, Dr. Henderson explores Mexico’s weaknesses at the time and how those weaknesses led to the war with the United States.

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

The Spanish-American war was called “a splendid little war,” due to its short duration which lasted four months. Nonetheless, it was not as a little as said; African American soldiers who fought in the war received many discriminations; also, about 2,000 Americans died from tropical illnesses. Thanks to the secretary of state, John Hay, the 100-day war on Spain was called “the splendid little war.” Hay wrote to Roosevelt, July 27, 1898: "It has been a splendid little war, begun with the highest motives, carried on with magnificent intelligence and spirit, favored by that Fortune which loves the brave" (Credit Splendid Little War on John Hay, 1991).

The war with Mexico is long remembered as an episode, and by no means is it an unimportant one. With the events that led up to its happening, from the Manifest Destiny to the disputes on territory, it has severely marked the United States. American historians regard the Mexican-American war as “the foulest blot on our national honor”. (sfmuseum.org) Unethical actions were taken gain Mexican territory. Polk and his hunger for land drove him to find some devious way to fight a war with Mexico. His belligerent attitude in regard to this war was the “foulest blot on our national honor.” However, as one studies the events that led to it, was it an unprovoked act of aggression? Or did the US unjustifiably lure Mexico into one of the bloodiest wars on American soil?
