Final answer:
General Mier y Terán reported the growing influence of Anglos in the Texas settlements to the Mexican government in 1828, impacting U.S.-Mexico relations and policies.
Step-by-step explanation:
General Mier y Terán from Mexico City conducted a tour of Texas in 1828 and reported to the Mexican government that there was a growing influence of Anglos in the Texas settlements. This observation led the Mexican government to take action in 1830 by forbidding future U.S. immigration and by increasing its military presence in the region. Despite these measures, settlers continued to illegally cross into Texas, significantly increasing their numbers by 1835.
The presence and conduct of the Anglo-American settlers in Texas contributed heavily to the uneasy relations between Mexico and Texas, eventually contributing to the lead-up to the Texas Revolution and subsequent events such as the Mexican-American War.
