Answer:
1. Santa Anna dissolved the social pact that guaranteed the sovereignty of Mexican states.
2. He revoked the Mexican constitution, giving the federal government sovereignty over state governments.
3. Because Texans had to submit to the guidelines of the federal government that ended some privileges that they had such as tax exemption, self-government and government tariffs
Step-by-step explanation:
Santa Anna revoked the Mexican constitution, which saddened Mexicans who saw it as a betrayal and started the Texan revolution that sought to declare Texan territory as independent from the Mexican government.
This was because the Mexican constitution stated that Mexico was a country with "a federal government of sovereign states." This allowed Mexican states to self-govern and have no relationship of submission to the federal government. In addition to the privilege of self-government, states had the privilege of not paying federal taxes or financing government regulations that did not apply to their territory. However, Santa Anna revoked that and established that Mexico would have a central government, the federal government, to which all states would submit. This infuriated the Texans and started the Texan revolution.
