The Mexican American War was a conflict between the United States and Mexico. This was a war over land, Mexico was fighting to keep the land that they had acquired from their independence over Spain. The U.S. wanted more of Mexico’s northern lands and especially Texas. One of the main causes of the Mexican American War was the “Manifest destiny” that meant that the U.S. had a God-given right to colonize the whole continent of North America. Another major cause of the Mexican American War started with the Texas War of independence. In the 1820s Mexico had actually permitted Americans to live in Mexican territory, Mexico needed settlers and started to colonize it but the only difference was that the Mexican government was taxing and controlling the population in their territory. Americans having this Manifest destiny idea did not want to live over Mexican dominance. A large number of Americans migrated west searching for land, most of those areas had people living in them but that didn’t stop them, they thought that Americans would do a better job of governing the land then the Native Indians and Mexicans. Manifest Destiny was a view that most Americans and especially President Polk had in the 18th century, which led to America stealing a territory that wasn’t rightfully theirs.
This conviction that the U.S. had the God-given right to assume control and "humanize" the North American continent came to be more famous as additional Americans settled in western lands. The way that the majority of the prior regions as of recently had people living on them was typically overlooked, with the state of mind that Americans, with its high standards and Christian morals, might improve way to govern than the Native Americans and Mexicans. Manifest Destiny wasn't supposed to be violent. In 1835 and 1845, the U.S. offered to buy California from Mexico, for 30 million dollars. The Mexican government rejected the chance to offer 50% of its nation to Mexico's most threatening neighbor.
The second main explanation for the war was the Texas War of Independence and the resulting addition of that territory to the United States. In 1835, Texas revolted, and there were numerous battles, the Mexican President was captured and compelled to sign the Treaty of Velasco in 1836. This treaty gave Texas its independence, however numerous Mexicans declined to acknowledge the lawfulness of this report, Santa Anna was imprisoned. The Mexican government continued to attack U.S. troops around the border and many Americans agreed with the Texans in these clashes with the Mexicans. As an effect of the continuous attacks, the American people became very racist and stereotypical against the Mexican individuals and government. Mostly because of the continuous dangers with Mexico, on July 4, 1845, Texas chose to join the United States and the U.S. congress approved the annexation.
Mexico obviously did not like the thought of its breakaway territory turning into an American...
