USA HISTORY

Detailed explanation-1: -With its triumph in the Mexican-American War, the United States seemingly realized its Manifest Destiny by gaining an immense domain (more than 525, 000 square miles [1, 360, 000 square km] of land), including present-day Arizona, California, western Colorado, Nevada, New Mexico, Texas, and Utah.

Detailed explanation-2: -The Mexican-American War was the first major conflict driven by the idea of “Manifest Destiny"; the belief that America had a God-given right, or destiny, to expand the country’s borders from ‘sea to shining sea’.

Detailed explanation-3: -Under the terms of the treaty negotiated by Trist, Mexico ceded to the United States Upper California and New Mexico. This was known as the Mexican Cession and included present-day Arizona and New Mexico and parts of Utah, Nevada, and Colorado (see Article V of the treaty).

Detailed explanation-4: -From 1846 to 1848, U.S. and Mexican troops fought against one another in the Mexican-American War. Ultimately, it was a battle for land where Mexico was fighting to keep what they thought was their property and the U.S. desired to retain the disputed land of Texas and obtain more of Mexico’s northern lands.

Detailed explanation-5: -What did the Mexican-American War have to do with Manifest Destiny? The concept of Manifest Destiny held that the United States had the providential right to expand to the Pacific Ocean. In 1845 the U.S. annexed the Republic of Texas, which had won de facto independence from Mexico in the Texas Revolution (1835–36).
