Lucius II, pope of the Catholic Church

Pope Lucius II, born Gherardo Caccianemici dal Orso, was head of the Catholic Church and ruler of the Papal States from 9 March 1144 to his death in 1145. His pontificate was notable for the unrest in Rome associated with the Commune of Rome and its attempts to wrest control of the city from the papacy. He supported Empress Matilda's claim to England in the Anarchy, and had a tense relationship with King Roger II of Sicily.
