American-Mexican War (Napoleon's World)

The American-Mexican War, in the United States known simply as the Mexican War and in Mexico as the Second Texan War, was a conflict between 1839 and 1845 involving the United States of America and the Empire of Mexico. The war was fought primarily in the future state of Texas and the states of Arkansas and Louisiana, although some conflict did emerge in what would one day become California as well as in current territories of Mexico.

The war resulted in an American victory following Taylor's Gambit, a brave landing at Veracruz that caught the Mexicans by surprise and with their capital at Ciudad Mexico unprotected. The American government demanded enormous concessions from the Mexican government resulting in the cessation of vast amounts of territory, including the modern states of Texas, New Mexico, California, Peninsula, Apachia, Nevada, Deseret, and parts of Sequoyah and Kansas. The war, to some historians, represents the moment that the United States cemented itself as the major New World power, as opposed to allowing then-mighty Mexico from achieving that role.
