What did the U.S. gain by winning the Mexican-American War? Mexico ceded nearly all the territory now included in the U.S. states of New Mexico, Utah, Nevada, Arizona, California, Texas, and western Colorado for $15 million and U.S. assumption of its citizens’ claims against Mexico.

The US won the war, and Mexico signed the Treaty of Guadalupe Hidalgo in 1848, which gave the US the area that would become the states of Arizona, California, New Mexico, Nevada, Utah, southwestern Colorado, and southwestern Wyoming. Mexico received 15 million US dollars and gave up its claims to Texas.

The Americans won the Mexican-American War, gaining the Mexican Cession and Mexico lost about one third of its territory. The Mexican Cession was what the Americans gained after the Mexican American war.

The fighting was at an end. By the Treaty of Guadalupe-Hidalgo (February 2, 1848), Mexico accepted the Rio Grande as its boundary. The treaty also gave the United States Mexico’s northern provinces of California and New Mexico.

The war affected the US, specifically Texas, and Mexico. For Mexico, there was loss of life, economic ruin, and huge damage to property. For the US, they gained huge new pieces of land. However the fight over what to do with it took center stage.

The Mexican-American war (1846-1848) changed the slavery debate. It almost doubled the size of the United States and began a debate, between Northerners and Southerners, over what to do with the newly acquired land.

On May 12, 1846, the United States Senate voted 40 to 2 to go to war with Mexico. President James K. Polk had accused Mexican troops of having attacked Americans on U.S. soil, north of the Rio Grande. But Mexico claimed this land as its own territory and accused the American military of having invaded.

The Mexican-American War, waged between the United States and Mexico from 1846 to 1848, helped to fulfill America’s “manifest destiny” to expand its territory across the entire North American continent.

The Mexican-American War marked a turning point in the debate over slavery in the U.S. by unleashing a massive tension between the North and South on what land would be free and what land would be slave.

The Mexican Cession (Spanish: Cesión mexicana) is the region in the modern-day southwestern United States that Mexico ceded to the U.S. in the Treaty of Guadalupe Hidalgo in 1848 after the Mexican–American War.

It abolished slavery in the new Arizona Territory, but did not abolish it in the portion that remained the New Mexico Territory. During the 1850s, Congress had resisted a demand for Arizona statehood because of a well-grounded fear that it would become a slave state.

Arizona. Arizona, formerly part of the Territory of New Mexico, was organized as a separate territory on February 24, 1863. The U.S. acquired the region under the terms of the 1848 Treaty of Guadalupe Hidalgo and the 1853 Gadsden Purchase. Arizona became the forty-eighth state in 1912.
