Mexican War

The Mexican war was fought in 1845-1848 mainly in U.S. interests, and due to the American belief of manifest Destiny; that expansion was the destiny of their growth.

This war was viewed differently from Mexican point of view as an invasion; this showed that they little power and the U.S. had chosen the right time for attacking and using Manifest destiny to encourage people to expand their territory. Having James Polk as president the U.S. was moving in to a territorial expansion, especially having the right resources and has chosen the correct period of time, time during which Mexico had social, political, and economic problems. A great influence in for which the U.S. chose this period was that Mexico had gained its independence from Spain not to long ago and they were still trying to become stable. The U.S. was far more developed and well established than Mexico; the U.S.'s economy, government, and economic status were by far some of the best during this period.

The American interest in the western expansion was supported by most of the northern part of the United States. This expansion also brought conflict to the U.S. because the citizens of the north said that the expansion was not only a territorial expansion, it was the expansion for slavery also. The period of 1845-1848 was a perfect period to expand due to the conflicts that Mexico had with cities like Monterrey, and Buena Vista. Mexico had a political instability as too many parties ran for presidency and during this period there was an exchange of presidency. The annexation of Texas began it all though Mexico knew they had no chance compared to the U.S.'s great economy useful to provide weaponry, and a society willing to fight for what they believe in "Manifest Destiny".

In a way the U.S. was also forced to expand because competition such as Great Britain, Russia and especially Mexico the owners of the land also wanted that land.
