Final answer:
Maria y Teran would have reported on the complex situation in Texas, where American settlers were resisting Mexican laws and measures meant to curb their influence, ultimately leading to the establishment of the Republic of Texas despite Mexico's attempts to maintain control.
Step-by-step explanation:
The evidence provided by Maria y Teran to the Mexican government regarding Texas would have related to the growing tensions and the shifts in power dynamics in the region. During the early 19th century, the Mexican government was concerned about the increasing influence of American settlers in Texas. Mexico implemented measures to counter this influence, such as outlawing slavery, which was directed at weakening the position occupied by Texan settlers since slavery was an economic pillar only in Texas within Mexico. Despite this, American settlers continued to immigrate into Texas, and these punitive measures often backfired, further fueling the desire for Texas's independence.
The eventual rise of the Texan push for independence saw the making of two treaties post the Battle of San Jacinto - one public and one private. The public treaty established the cessation of hostilities between Mexico and Texas but didn't recognize Texas as an independent republic, while the private treaty, signed by Santa Anna, was for Mexico to recognize Texas's independence, although Santa Anna later denounced it once he was back in Mexico City.
Various significant events took place during this time, such as the Republic of Fredonia declaration and the writing of a constitution for an independent Texas that included stipulations for a judicial system similar to the American one and the continuation of slavery, showcasing the settlers' intent to align more with the United States than with Mexican governance.
