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.
The vast majority were victims of diseases such as dysentery, yellow fever, malaria and smallpox. According to scholar V.J. Cirillo, a higher percentage of U.S. troops died from sickness during the Mexican invasion than any war in American history.
The Mexican–American War, also known in the United States as the Mexican War and in Mexico as the Intervención estadounidense en México (U.S. intervention in Mexico), was an armed conflict between the United States and
Mexico from 1846 to 1848.

The Mexican-American War was a conflict between the United States and Mexico, fought from April 1846 to February 1848. It stemmed from the annexation of the Republic of Texas by the U.S. in 1845 and from a dispute over whether Texas ended at the Nueces River (the Mexican claim) or the Rio Grande (the U.S. claim).
What were the 2 main causes of the Mexican-American war? Borders over TX and Mexico and Mexico being hostile over US annexing Texas.
It was started by a dispute by the Rio Grande and the Nueces River. The Mexican- American war was the first battle on foreign soil, fueled by the desire of James K. Polk to fulfill Manifest Destiny. The Americans won the Mexican-American War, gaining the Mexican Cession and Mexico lost about one third of its territory.
War with Mexico which began in 1846 when the U.S. annexed Texas and Mexico challenged the Border. Battles were fought in Texas, and Mexico was invaded from the Atlantic Ocean by General Winfield Scott. Scott attacked Mexico City and Chapultepec. The war ended with the treaty of Guadalupe Hidalgo in 1848.
The treaty effectively halved the size of Mexico and doubled the territory of the United States. This territorial exchange had long-term effects on both nations. The war and treaty extended the United States to the Pacific Ocean, and provided a bounty of ports, minerals, and natural resources for a growing country.
What led the United States to go to war with Mexico in 1846? No justification for war, Mexico had refused to sell the southwest. The Mexican War was inspired by the expansionist fervor manifest destiny, a majority of Americans supported the war. You just studied 13 terms!
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.
In the Mexican-American War, Mexico faced an enemy that was coming into its own as a military power. In March 1836, Mexican forces overran the Alamo in San Antonio, Texas, achieving victory over those who had declared Texas' independence from Mexico just a few weeks earlier.
The most immediate cause of the Texas Revolution was the refusal of many Texas, both Anglo and Mexican, to accept the governmental changes mandated by "Siete Leyes" which placed almost total power in the hands of the Mexican national government and Santa Anna. Many Mexicans felt exactly the same way.
The failure of the Wilmot Proviso only put off the issue of slavery for so long. With the Treaty of Guadalupe Hidalgo, Mexico ceded over 525,000 square miles of territory to the United States in exchange for $15 million and the assumption of Mexican debts to American citizens, which reopened the slavery issue. Area Mexico ceded to the United States in 1848, minus Texan claims. The Mexican Cession consisted of present-day U.S. states of California, Nevada, Utah, most of Arizona, the western half of New Mexico, the western quarter of Colorado, and the southwest corner of Wyoming.
Polk provoked it, the robbery of land, and the slavery expansion. Three main reasons America was unjustified in going into war with Mexico were that President James k. Polk provoked it, America's robbery of Mexico's land and the expansion of slavery. That is why America was unjustified to go into war with Mexico.
