Why did Santa Anna jail Stephan Austin?

Santa Anna jailed Stephen Austin in 1834 primarily due to Austin's role as a leader in the Texan fight for greater autonomy from Mexican rule. Austin had traveled to Mexico City to negotiate with the Mexican government for reforms and to address the grievances of American settlers in Texas. His advocacy for Texian interests was viewed by Santa Anna as a threat to his authority, leading to Austin's arrest on charges of inciting rebellion. This action further fueled tensions between the Texians and the Mexican government, ultimately contributing to the Texas Revolution.
