American victory

The Mexican–American War, also known as the Mexican War, the U.S.–Mexican War or the Invasion of Mexico, was an armed conflict between the United States of America and the United Mexican States from 1846 to 1848. It followed in the wake of the 1845 US annexation of Texas, which Mexico considered part of its territory, despite the 1836 Texas Revolution.

After its independence in 1821 and brief experiment with monarchy, Mexico became a republic in 1824. It was characterized by considerable instability, so that when war broke out in 1846, Mexico was ill-prepared for conflict. The war with the United States followed in the wake of decades of Native American raids in the sparsely settled north of Mexico, which prompted the Mexican government to sponsor migration from the US to the Mexican province of Texas to act as a buffer. Texans from both countries revolted against the Mexican government in the 1836 Texas Revolution, creating a republic not recognized by Mexico, which still claimed it as its national territory. The 1845 expansion of US territory with its annexation of Texas escalated the dispute between the United States and Mexico to open war.

In 1844 James K. Polk, the newly-elected president, made a proposition to the Mexican government to purchase the disputed lands between the Nueces River and the Rio Grande. When that offer was rejected, troops from the United States commanded by Major General Zachary Taylor were moved into the disputed territory of Coahuila. These troops were then attacked by Mexican troops, killing 12 US troops and taking 52 prisoners. These same Mexican troops later laid siege to a US fort along the Rio Grande. This would lead to the conflict that resulted in the loss of much of Mexico's northern territory.

US forces quickly occupied Santa Fe de Nuevo México and Alta California Territory, and then invaded parts of Central Mexico (modern-day Northeastern Mexico and Northwest Mexico); meanwhile, the Pacific Squadron conducted a blockade, and took control of several garrisons on the Pacific coast farther south in Baja California Territory. Another US army, under the command of Major General Winfield Scott, captured the capital Mexico City, marching from the port of Veracruz.
