  • Texas Revolution was the American tendency to expand and their longing to satisfy Manifest Destiny. Because of their desire to make the United States a transcontinental nation that stretched from the Atlantic to the Pacific Ocean. - Americans under Stephen Austin were aliens to the Mexicans. The Americans ignored all the stipulations of their settlement in the region -Some three hundred Americans were invited by the Mexican government to populate Mexico in order to help the Mexican government ride its population of Native Americans. But the Americans took over.
  • The President at the time was James K Polk, He was for the idea of Manifest destiny, which was the desire to expand the united stats. He wanted Mexican land and offered to pay for it buy sending Slidell to make the Mexican gov. their offer, know as Slidells mission, When Mexico refused Polk put solders along the Rio Grande, which was the Boarder between the to lands, In his attempt to get Mexico to start the war. On April 25 th 1846 Mexican troops crossed the Rio Grande and attacked general Taylor’s command. 16 American troops were killed or wounded. Polk got what he wanted, the congress agreed to declare war on Mexico. The purpose of the war was to gain the Mexican land before the Europeans could get a hold of it and Americans desire of Manifest destiny.
  • domestic effects of the war in America : total expansion, increased by about one – third, greater then the Louisiana Purchas. The new lands gained meant new states and with new states the issue of slavery became prevalent. Further conflicts in congress arose as to how to decide whether or not the new land would be slave territory or not. If slavery would or would not be permitted then the delicate balance of northern and southern states political power would tip. Foreign effects of the war were: Mexicans that lived in the newly won territory of the US were given citizenship, Mexico lost about half of its country. The war also marked an ugly turning point in US and Latin America as a whole. Mexicans had animosity built up for the US for coming in and taking there land. But the fact that they were given some money and still had some land left eased the animosity slightly. The war also gave more international respect to the American military.
  • The Mexicans wanted the war because they thought they were going to destroy the US military and embarrass them. Teach them a lesson and free the black slaves. When in all of actuality Mexicans were upset that they lost their land and when the south began to secede from the union and the civil war began. Americas reaction : The idea of manifest destiny became a reality and new states were added , Texas and California. The only problem was that the south wanted to use the newly acquired land as slave territory for agriculture. The north did not want this so once again conflict arose in the US which would eventually lead to the civil war.
  • As a result of the war, militarily, the Spanish army was ravished and they lost ALL the battles. See chart. They also had a higher casualty rate. Their country was cut in half and once again the US was doubled. See map.
  • The lone term domestic effects of the war were: The issue of whether or not the new states would be slave stats because it lead to the civil war which caused the greatest amount devastation in American history it tore apart a nation. there was now an ability to connect with California and eventually railroads would be built and tread would expand. Foreign long term effects were: Mexico was devastated it Leader ship struggled it could not revive its self politically economically and socially. There were civil wars turmoil and foreign intrusion. Mexican Americans relations were forever hindered. And New leaders tried to unite Mexico and drive out invaders.
