Step-by-step explanation:
Mier y Teran listed three problems in his report to the Mexican government:
Slavery: The Mexican government's 1829 abolition of slavery caused discontent among American settlers who had brought enslaved people to Texas.
Mexicans outnumber Anglos 4:1: The disparity in population created tensions, with American settlers regarding Mexicans as dishonest, ignorant, and backward.
Anglos not converting to Catholicism or practicing Mexican citizenship: Many American settlers refused to be naturalized as Mexican citizens and ignored Mexican laws, including those related to religion and citizenship.
