What are the effects of the Mexican -american war

The Mexican-American War (1846-1848) had a number of effects on both the United States and Mexico.

For the United States, the war resulted in the acquisition of a large amount of land, including the present-day states of California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming. This land acquisition greatly increased the size of the United States and helped to fulfill the idea of Manifest Destiny. The war also helped to solidify the United States as a major power in the Western Hemisphere.

For Mexico, the war was a major setback. Mexico lost a large amount of land to the United States, and the war also caused a great deal of economic and political instability. The war also caused a great deal of resentment towards the United States, which has lasted to this day.
