History of Hispanic and Latino Americans in the United States
In 1821, Mexico gained independence from Spain, annexing the southwest of the present United States, including Arizona. As missions began to wither, Mexico began auctioning off more land, causing the Pimería Alta and the Apachería to shrink as territory expanded. In the meantime, American mountain men began to enter the region, looking to trap beavers for their pelts. In 1836, Texas declared independence from Mexico and claimed much of the territory in the northern lands of Mexico. When the United States annexed Texas in 1846 over the strong objections of the Mexican government, U.S. troops moved into disputed territory. The hostilities erupted in the Mexican–American War (1846–1848). The U.S. occupied Mexico City and forced the newly founded Mexican Republic to give up its northern half, including the later Arizona.
Ignacio Elizondo
The Mexican War of Independence from Spain began with the "grito" of the Roman Catholic priest, Miguel Hidalgo y Costilla, on September 16, 1810. Initially Elizondo, stationed in Texas, took the side of the rebels in the Casas Revolt. Elizondo had the responsibility of guarding royalist prisoners in Monclova, Coahuila. There, or possibly earlier, he was persuaded to join the royalists. Some historians debate whether General Ramon Díaz de Bustamante or Bishop Primo Feliciano Marín de Porras won Elizondo over to the royalists. Others believe he was converted by Manuel María de Salcedo of Texas and Simón de Herrera of Nuevo León, while the two royalist governors were his prisoners.
