The Mexican-American War was a conflict between the United States and Mexico, lasting from 1846 to 1848. The U.S. declared war after Mexico refused to acknowledge America’s claims over disputed territories in Texas, New Mexico, and California.

The rebellion resulted in an independent Republic of Texas that later joined the United States in December 1845 as its 28th state ” much to Mexico’s displeasure. To punish this perceived slight by America, Mexican forces invaded several border towns in March 1846 leading President James K Polk to request Congress declare war on April 25th that year; it did so four days later sending 15,000 troops southward led by General Zachary Taylor (later 12th US president).
