How did Mexico view the American annexation of Texas?

The annexation of Texas by the United States in 1845 was a controversial event that had significant implications for Mexico. The annexation was perceived by many Mexicans as an act of aggression and expansionism by the United States. Here's how Mexico viewed the American annexation of Texas:

1. Violation of the Treaties: Mexico viewed the annexation as a violation of the 1831 Treaty of Limits between Mexico and the United States, which established the boundary between the two countries. Mexico argued that the United States had no legal right to annex Texas, as it was considered part of Mexico's territory.

2. Diplomatic Tensions: The annexation led to heightened diplomatic tensions between Mexico and the United States. Diplomatic relations were severed, and both countries engaged in a series of diplomatic protests and threats of war.

3. Fear of Further Expansion: Mexico feared that the annexation of Texas was just the first step in a broader plan by the United States to expand its territory further into Mexico. The Mexican government and public saw this as a threat to their sovereignty and territorial integrity.

4. Loss of Territory: The annexation meant that Mexico lost a significant portion of its northern territory. Texas was a vast region that encompassed present-day Texas, as well as parts of Oklahoma, Kansas, Colorado, Wyoming, and New Mexico.

5. Historical and Cultural Ties: Texas had been part of Mexico for several centuries, and many Mexicans had historical, cultural, and familial connections to the region. The annexation meant the loss of a beloved and significant part of Mexico's national identity.

6. Economic Impact: The annexation of Texas also had economic consequences for Mexico. Texas had been an important source of revenue for Mexico, with major agricultural and livestock industries. Losing Texas meant a loss of economic resources and potential future economic growth for Mexico.

In summary, Mexico viewed the American annexation of Texas with a combination of anger, resentment, and fear. It was seen as an unjust act that violated international treaties and threatened Mexico's territorial integrity and sovereignty. The annexation had significant diplomatic, political, economic, and cultural implications, and played a major role in shaping the subsequent relationship between Mexico and the United States.
