General Mier y Terán's 1828 Inspection of Texas: Key Findings

In 1828, Mexican General Manuel de Mier y Terán led a boundary commission to assess conditions in Texas. His report profoundly influenced Mexican policy.

Critical Observations

1. Demographic Imbalance: Anglo-American settlers vastly outnumbered Mexican citizens (est. 10:1 to 20:1 in some areas). Most entered illegally after 1824 colonization laws.
2. Non-Assimilation: Settlers retained U.S. language, laws, religion (Protestant), and cultural practices. Few converted to Catholicism or learned Spanish as required.
3. Land Speculation & Fraud: Empresario grants abused; speculators claimed vast tracts without settling families. Squatting on public lands rampant.
4. Economic Orientation: Trade flowed north to New Orleans (via Nacogdoches), not south to Mexico. U.S. currency dominated.
5. Weak Mexican Authority: Few garrisons, minimal customs enforcement, local alcaldes often Anglo appointees. Central government had little real control.
6. Slavery Expansion: Despite Mexican abolition (1829), settlers brought enslaved people, calling them "indentured servants" to circumvent law.

Policy Consequences

Mier y Terán's alarming report led directly to the Law of April 6, 1830, which:

• Banned further U.S. immigration.
• Suspended unfulfilled empresario contracts.
• Established new presidios (forts) and customs houses.
• Encouraged Mexican/European colonization with incentives.
• Prohibited import of enslaved people.

Outcome

The law inflamed Anglo colonists, fueled the "Texas Revolution" narrative of oppression, and was a proximate cause of the 1835–36 rebellion. Mier y Terán, despondent over Texas's trajectory, committed suicide in 1832.
