Mier y Teran was a Mexican general and statesman who served as the Inspector General of the Provincias Internas, a region comprising much of present-day Mexico and the southwestern United States. In 1827, Mier y Teran was commissioned by the Mexican government to conduct a survey of the borderlands between Mexico and the United States and to report on the state of the region.
In his report to the Mexican government, Mier y Teran recommended that the Mexican government take a number of steps to strengthen its control over the borderlands, particularly the region of Texas. Specifically, he recommended that the government:
Increase the number of military garrisons and forts in the region to deter incursions by American settlers and to protect against Native American attacks.
Encourage the settlement of Mexican families in the region to establish a strong Mexican presence and to prevent the spread of American influence.
Promote the development of agriculture and other industries in the region to generate economic growth and to provide a source of revenue for the government.
Establish a system of grants and land subsidies to encourage Mexican settlers to move to the region and to discourage American settlers from moving into the area.
Implement stricter immigration policies and enforce existing laws more strictly to prevent American settlers from entering the region without proper documentation.
Overall, Mier y Teran's recommendations were designed to strengthen Mexico's control over the borderlands and to prevent the spread of American influence in the region.
