How did the views of mexican and american differ about texas

Anglo (meaning non-Hispanic white) migration to Texas began in earnest after Mexico secured its independence from Spain in 1821. In the new republic, Texas was just one part of the state of Coahuila-Texas, a region in Mexico's northern borderlands in which Native communities were powerful. Mexican families lived throughout the northern portion of Coahuila-Texas—the wealthiest of whom were known as Tejanos—and to the Comanche and Lipan Apache they were unwelcome. Viewed from the perspective of the region's Native communities, both Tejano and Anglo settlers were undocumented immigrants.
