The Mexican Indian Wars[1] were a series of conflicts fought between Spanish, and later Mexican, Guatemalan, Honduran, Salvadoran and Belizean forces against Amerindians in what is now called Mexico and surrounding areas such as Belize, Guatemala, Honduras, El Salvador and Southern/Western United States. The period begins with Spanish conquest of the Aztec Empire in 1519[2] and continued until the end of the Caste War of Yucatán in 1933.[3]
