This is a Wikipedia topical outline of articles about the Mexican American War.

The Mexican–American War (April 25, 1846 – February 2, 1848), known in Mexico as the United States intervention in Mexico, was an invasion of Mexico by the United States. It followed the 1845 American annexation of Texas, which Mexico still claimed as its territory, and a dispute over the border: Texas and the U.S. asserted the Rio Grande, Mexico the more northerly Nueces River. President James K. Polk, elected in 1844 on a platform of territorial expansion, offered $25million for the disputed land and California; Mexico refused. He then sent troops into the disputed territory, where Mexican forces repelled them on April 25, 1846, giving Polk grounds to obtain a declaration of war from Congress.

U.S. forces occupied Santa Fe de Nuevo México and Alta California, the Pacific Squadron blockaded Mexico's Pacific coast, and Major General Winfield Scott landed at Veracruz and captured Mexico City in September 1847. The 1848 Treaty of Guadalupe Hidalgo, negotiated by Nicholas Trist after Polk had recalled him, ended the war: Mexico ceded the territory of present-day California, Nevada, and Utah and parts of Arizona, Colorado, New Mexico, and Wyoming, gave up its claims on Texas, and accepted the Rio Grande as its northern border with the United States, while the U.S. paid $15million and assumed $3.25million of Mexican debt to U.S. citizens. The acquisitions intensified the American debate over slavery and are seen by some scholars as a step toward the American Civil War, in which many officers who had gained experience in Mexico later held prominent commands. Mexico was left with heavy casualties, ruined finances, political turmoil, lost prestige, and the loss of more than half its territory.
