The itself, and Texas was endeavoring to become

   The United States of America in the 1800’s was a quickly developing nation. Many individuals moved west for religious opportunity while others were solid adherents to the Manifest Destiny. Keeping in mind the end goal to possess more land, pioneers wanted to venture westward because there was more undeveloped land. Since the vast majority of the west was part of Mexico, this was a difficult task. Fortunately, Mexicans likewise needed pilgrims in their western terrains since that region was not created. Mexico welcomed Americans to settle in their property. In any case, the two nations had numerous distinctions. It was only a matter of time until the United States and Mexico went to war. The United States was advocated in going to war since Mexico had shed American blood on American soil, Texas was a free republic and had the privilege to oversee itself, and Texas was endeavoring to become apart of the United States.   Mexico had urged Americans to settle in the territory of Texas, which was a piece of Mexico at the time. After the Texans and Mexicans battled, Texas won its independence from Mexico in 1836. In 1846, America sent a troop of men lead by General Zachary Taylor to the Texan fringe to ensure the Mexicans weren’t endeavoring to attack Texas (Doc B). This angered Mexicans since it influenced it to appear as though Texas was allied with America. The debate that took after prompted the demise of sixteen Americans. Additionally, the Mexicans believed that the entry of General Zachary Taylor was an assault, which prompt the battles of Palo Alto and Resaca de la Palma (Doc C). This demonstrates Mexico had ventured out battling the United States. In the long run, the Mexicans were compelled to surrender. As to which side let go to begin with, this can’t be resolved. In one letter to Congress, James Polk expressed, “We have attempted each exertion at compromise. The measure of patience had been depleted even before the current data from the boondocks of the Del Norte. Be that as it may, now, … Mexico has passed the limit of the United States, has attacked our domain and shed American blood upon the American soil” (Doc B).    Before Texas became a part of the United States, it was a free republic. An autonomous republic has the privilege to represent itself and set itself apart from different countries. Texas respected the Rio del Norte to be the Texan fringe (Doc B). This implies Texas now has the decision to do whatever they wish. Charles Sumner, a state lawmaker from Massachusetts, stated, “… in looking for augmentation of bondage, (our own subjects denied) the colossal certainties of American opportunity” (Doc D). In the event that Texas is free, it has the privilege to claim slaves. Likewise, states in the United States effectively possessed slaves, so the point can’t be contended any further. Sumner likewise said Americans got slaves Mexico in resistance of Mexican law (Doc D). Be that as it may, Mexico welcomed Americans into Mexico and Mexico ought to have understood that Americans would have diverse ways. Likewise, Texas was endeavoring to wind up some portion of the United States, which implied that the United States had a privilege to go to war with Mexico.    Since Mexico couldn’t represent the greater part of its domain, they welcomed Americans in. Since Americans were settling in a uninhabited Mexican area, the proportion of Americans to Mexicans expanded (Doc A). In the end, the American way of life assumed control, and requested distinctive rights. In Document C, Velasco-Marquez said the arrangement marked among Texas and the U.S. and furthermore the way that Texas needed to be attached to the U.S. was a demonstration of war. Texas had the privilege to be a piece of the U.S., and if Mexico thought about this a demonstration of war with Texas, at that point the U.S. had the privilege to be included as well (Doc C). At long last, James Polk stated, “The attack was undermined exclusively in light of the fact that Texas had decided… to add herself to our Union” (Doc B). At that point America had the privilege to pronounce war.     When Mexico demonstrated hostility to Texas, the United States had a privilege to go to war with Mexico since Texas was a free republic and needed to become a part of the United States. From these advocates, it can be presumed that the United States was justified into going to war with Mexico.
