Mexican War: causes, results
Causes: annexation of Texas, diplomatic ineptness of U.S./Mexican relations in the 1840's and particularly the provocation of U.S. troops on the Rio Grande. The first half of the war was fought in northern Mexico near the Texas border, with the U.S. Army led by Zachary Taylor. The second half of the war was fought in central Mexico after U.S. troops seized the port of Veracruz, with the Army being led by Winfield Scott. Results: U.S. captured Mexico City, Zachary Taylor was elected president, Santa Ana abdicated, and Mexico ceded large parts of the West, including New Mexico, Colorado, Utah, Arizona, Nevada and California, to the U.S.
