Final answer:
American settlers in Texas disallowed further American immigration and plotted a revolution as a result of Mexican restrictions. They were dissatisfied with Mexican policies and laws, such as the prohibition of slavery and the requirement to practice Catholicism. The correct answer is option 1. and 2.
Step-by-step explanation:
As a result of Mexican restrictions in Texas, American settlers there plotted a revolution. The Mexican government, in an effort to control the burgeoning American populace, passed laws that aimed to integrate Americans into Mexican society. However, these Americans often held on to their own cultural, religious, and economic practices, notably in relation to slavery. American settlers in Texas were significantly different from the Mexican citizens, known as tejanos, in that many were slave owners and they remained religiously distinct as the majority were Protestant and opposed to Roman Catholicism, which was prevalent among tejanos.
The abolition of slavery by the Mexican government was the greatest source of discontent among settlers, most of whom were from southern states and desired to continue the institution of slavery. This, along with the prohibition of public practice of non-Catholic religions and the settlers' desire for Texas to join the United States as a new slave state, fomented revolutionary sentiments, eventually leading to the Texas Revolution.
