Question

1. what was the cause of the mexican war?

Explanation:

The Mexican - American War (1846 - 1848) was mainly caused by the dispute over the territory of Texas and the border between Texas (after its annexation by the US) and Mexico. The US annexed Texas in 1845, and Mexico still considered Texas its territory. Also, the US had expansionist desires to acquire more territory, especially the Southwest (including present - day California, Nevada, Utah, etc.). The US sent troops to the disputed area (between the Nueces River and the Rio Grande), and when Mexican troops clashed with US troops, the US declared war.

Answer:

The main cause of the Mexican - American War was the territorial dispute over Texas (after the US annexed Texas, Mexico still claimed it) and the border between Texas and Mexico, along with US expansionist ambitions to acquire the Mexican - controlled Southwest territory. The immediate trigger was the military clash between US and Mexican troops in the disputed border region, which led the US to declare war on Mexico.
