Article

Pope Gregory IX (Latin: Gregorius IX; born Ugolino di Conti; 1145 – 22 August 1241) was head of the Catholic Church and the ruler of the Papal States from 19 March 1227 until his death in 1241. He is known for issuing the Decretales and instituting the Papal Inquisition, in response to the failures of the episcopal inquisitions established during the time of Pope Lucius III, by means of the papal bull Ad abolendam, issued in 1184.

He worked initially as a cardinal, and after becoming the successor of Honorius III, he fully inherited the traditions of Gregory VII and of his own cousin Innocent III, and zealously continued their policy of papal supremacy.
