Why was Stephen f Austin arrested in Saltillo Mexico?

Stephen F. Austin was arrested in Saltillo, Mexico, in 1833 due to his efforts to negotiate greater autonomy for Texas within Mexico. He had traveled to Mexico City to present a petition for reforms, but upon his arrival, political tensions were high, and the Mexican government viewed his actions with suspicion. Austin was detained for several months, accused of being part of a conspiracy against the Mexican government, but he was eventually released and returned to Texas. His arrest heightened tensions between Texan settlers and the Mexican authorities, contributing to the eventual Texas Revolution.
