Final answer:
Santa Anna's rule resulted in the loss of Texas to the United States and political instability due to the dissolution of Congress. This centralization of power led to the Texans' revolt and declaration of independence.
Step-by-step explanation:
Santa Anna's rule had several consequences, including the loss of Texas to the United States, a factor that later led to the Mexican-American War. Under Santa Anna's rule, the Mexican Constitution of 1824 was overturned, resulting in the dissolution of Congress and the establishment of a centralized government backed by the military. This centralization of power led to political instability and the loss of political voice for Texans, which ultimately fueled their revolt and declaration of independence.
