How did the Mexican-American war change America?

Answer 1

There is no doubt in anyone's mind that California, one of the world's strongest self- sufficient economies, if it was a separate country all by itself; was the main prize that changed the United States for the better.

Answer 2

After America won the Mexican-American War, we signed the Treaty of Hidalgo Guadalupe in 1848; it was the treaty that ended the war. The United States paid Mexico 15 million dollars and agreed to protect the 100,000 Mexicans living in the territory. Mexico agreed to give up Texas and the areas known as the Mexican Cession.

Answer 3

The Treaty of Guadalupe Hidalgo provided a financial settlement for Mexico and the US acquired present day California, Arizona, Utah, Nevada, New Mexico and certain other Mexican claims.
