At the end of the century, the Blue Penitents worshiped at the Saint-Jérome church. The local parlement condemned the Protestants, exercising its power in the trial and execution of Jean Calas. Toulouse's population supported the parlement when it felt threatened by the monarchy, and the eight Capitouls were now chosen by the parlement. 19th century The French Revolution changed Toulouse's role and its political and social structure.
