What was a major change that occurred during the Mexican national era in Texas?

During the Mexican national era in Texas, a major change that occurred was the influx of American settlers into the region. The Mexican government actively encouraged the migration of American settlers into Texas, offering land grants and incentives to attract settlers. This led to a rapid increase in the American population in Texas, which eventually outnumbered the Mexican population. The influx of American settlers brought new ideas and customs to Texas and helped shape its cultural and political landscape.
