Describe the historical circumstances that led to the mexico american war

Causes of The Mexico American war.

Explanation:

In 1836, Texas gained independence from Mexico.The United States initially declined to integrate it into the union, mainly because northern political interests were resistant to a new slave state being created. Furthermore, the Mexican government sponsored border raids and threatened that any effort to invade would lead to war.

On April 25, 1846, under General Zachary Taylor's orders, Mexican cavalry attacked a group of U.S. soldiers in the disputed area, killing around a dozen. They then laid siege along the Rio Grande to an American fort. Taylor called for reinforcements and was able to defeat the Mexicans in the battles of Palo Alto and Resaca de la Palma with the aid of superior arms and cannons.
