Why did the coup led by Antonio Lopez de Santa Anna anger Anglo Texans and Taejon's?

The coup led by Antonio Lopez de Santa Anna angered Anglo Texans and Tejanos because it centralized power in the Mexican government and curtailed the autonomy that Texas had enjoyed under the Constitution of 1824. Santa Anna's abolition of the federalist system and imposition of a more authoritarian regime threatened their rights and freedoms. Additionally, the increased military presence and enforcement of Mexican laws alienated many Anglo settlers, leading to rising tensions and ultimately contributing to the Texas Revolution.
