took place in the Lateran Basilica (4 June 1133), but otherwise the expedition proved abortive. Innocent II invested Lothair as emperor and the territories belonging to Matilda of Tuscany in return for an annuity of 100 pounds of silver paid to the pope. After Lothar's hasty departure from Rome, Innocent fled to Pisa. In May 1135, Innocent convened the council of Pisa, which was attended by over one hundred clerics and abbots. Innocent II had the council declare antipope Anacletus II and his supporters excommunicated. The second expedition by Lothar III in 1136 was no more decisive in its results, and the protracted struggle between the rival pontiffs was terminated only by the death of Anacletus II on 25 January 1138. In March 1139, in the Omne Datum Optimum, Innocent II declared that the Knights Templar—a religious and military organization then twenty-one years old—should in the future be answerable only to the papacy. Second Lateran Council At the Second Lateran council of April 1139, King Roger II of Sicily, Innocent II's most uncompromising foe, was excommunicated. Can. 29 of the Second Lateran Council under Pope Innocent II in 1139 banned the use of crossbows, as well as slings and bows, against Christians. Treaty of Mignano On 22 July 1139, at Galluccio, Roger II's son Roger III of Apulia ambushed the papal troops with a thousand knights and captured Innocent. On 25 July 1139, Innocent was forced to acknowledge the kingship and possessions of Roger with the Treaty of Mignano. Innocent II died on 24 September 1143 and was succeeded by Pope Celestine II. Legacy In 1134, Innocent elevated as cardinal-nephew his nephew, Gregorio Papareschi. He did the same for his brother Pietro Papareschi, whom he made cardinal in 1142. Another nephew, Cinthio Capellus (died 1182), was also a cardinal, raised to the cardinalate in 1158, after Innocent's death. Aside from the complete rebuilding of the ancient church of Santa Maria in Trastevere, which boldly features Ionic capitals from former colonnades in the Baths of Caracalla and other richly detailed spolia from Roman monuments, the remaining years of Innocent's life were almost as barren of permanent political results as the first had been. In the Lateran palace, he had a portrait painted depicting Lothar's oath to preserve the privileges of the city of Rome. Innocent's efforts to undo the mischief wrought in Rome by the long schism were almost entirely neutralized
