Reasons For The Mexican American War

American-Mexican War The Mexican-American War marked the first American military battle to be fought on foreign soil. The Mexican American War was mainly driven by the idea of “Manifest Destiny”; the belief that the United States had a right to spread across the continent to the Pacific Ocean. The motives that were really behind Manifest Destiny was the acquisition of new territory ,and the Americans wanted territories which were relatively uninhabited by people they considered inferior, such as Indians, blacks and Mexicans. President Pork provoked war with Mexicans with the aim of pushing Mexico into negotiating with Americans. To achieve this, he was willing to threaten them with war. His aim was to convince Mexicans

With the end of the Mexican War, the United States absorbed one third of that nation’s total area. Even though American’s gained a considerable amount of land, it created great political sectionalism in America. Mexico was fighting to keep what they thought was their property and the U.S desired to retain the disputed land of Texas and obtain more of Mexico’s northern lands. This fast expansion of the size of America combined with a number of other military successes and improvement of the country’s infrastructure and communication powered ideas of Anglo-Saxon sovereignty, which merged with America’s pride to create a manifest destiny.

Abraham Lincoln also gave a speech questioning the Mexican American war that he believed was unnecessary. Lincoln wanted to know if blood was indeed shed on United States soil. In addition, some northerners oppose the war because they were against slavery. David Wilmot proposed a resolution prohibiting slavery from all territory acquired from Mexico. Northerners supported the Wilmot Proviso, but Southerners felt that prohibiting slavery was a violation of their rights .Manifest Destiny was a justification used by southerners for extending slavery. The southern states had the desire to gain more slave states and this was a view held by many Northern states.
