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.
History of Mexico
The fact that there was an existing prehispanic tradition of writing meant that when the Spanish friars taught Mexican Indians to write their own languages, particularly Nahuatl, an alphabetic tradition took hold. It was used in official documents for legal cases and other legal instruments. The formal use of native language documentation lasted until Mexican independence in 1821. Beginning in the late twentieth century, scholars have mined these native language documents for information about colonial-era economics, culture, and language. The New Philology is the current name for this particular branch of colonial-era Mesoamerican ethnohistory.
