Detailed explanation-2: -The Mexican Cession as ordinarily understood (i.e. excluding lands claimed by Texas) amounted to 525, 000 square miles (1, 400, 000 km2), or 14.9% of the total area of the current United States.

Detailed explanation-3: -His charge at the Alamo during the Texas Revolution is a famous Mexican victory, but his defeat at San Jacinto ultimately led to the state’s independence (1836) (49). Twelve years later, Santa Anna’s failed campaign in the Mexican-American War caused Mexico to cede half of its territory (50).

Detailed explanation-4: -On February 2, 1848, the Treaty of Guadalupe Hidalgo was signed, by which Mexico “sold” half of its territory to the United States. With this agreement, the current states of California, Arizona, Nevada, Utah, as well as part of Colorado, New Mexico, and Wyoming became part of the United States.
