1184
The Bull was issued by Pope Lucius III To abolish diverse malignant heresies. The Third Lateran Council of 1179 had set systems to re-establish powers threatened by the conflict between state and papal power, called the Investiture dispute, as well as condemn some heresies, and the Bull was a natural follow on. 1209 marks the beginning of the Albigensian Crusade, ostensibly against heretics; 1233 is the date of the decretal by Pope Gregory IX which established the Papal Inquisition to regularise the persecution of heresy; 1483 is the year Torquemada was appointed the first grand inquisitor of the Spanish Inquisition.
