It is possible to claim that the secession of Texas was not caused by a coordinated effort from the United States to undermine the relationship between the province and the Mexican government. The two entities might have had a loose relationship due to the high population of U.S. migrants when compared to Hispanic settlers. Then, the dominant majority might have chosen to separate from the state that did not share its religion or view on slavery and to join the northern country, which was home for many of the migrants. Ultimately, Mexico might not have had enough power to compete with the United States in its influence on distant territories such as Texas.
The U.S. had established a relationship of power with the Native Americans in the area due to the length of time it had spent working with them. Mexico, however, had not had to contend with native tribes since it had devastated the Aztec empire during the initial colonization. Thus, the nation lacked the resources to deal with continued raids in the North, which may have been provoked by the States to weaken the Hispanic state. The Anglo-American settlers watched the Mexican government’s failure to perform its duties and grew disillusioned with their new nation. They recalled the state of Native Americans in the States and chose to merge with the more powerful country.
However, the resources of the U.S. were superior in more regards than just the removal and containment of Native Americans. Furthermore, the larger nation believed itself to be justified in aggressive expansion, claiming that it would benefit the world at large. When Texas eventually left Mexico and joined its other neighbor, the southern country declared war on the United States, which is lost. In peace terms, the United States of America and the United Mexican States agreed that the territory would go to the former, and Mexicans who lived there could either leave or become U.S. citizens. Mexico was outmatched by the other nation in every regard, and so there was little it could have done to prevent the eventual change of ownership of Texas.
Mexico was never able to establish a close and binding relationship with its Texan territories, as the colonization plans were interrupted soon after their inception by the independence war. The States, however, had both designs for the land and the manpower to conquer and colonize it. It likely caused the intensification of Native American attacks to emphasize the inability of the Mexican government to deal with the issue. Then, it influenced the Anglo-American majority of the population and convinced it to join the more secure nation. The acquisition was defended from Mexico by force, which might have been employed to annex Texas had the subtle design failed.
