Election of Alexander III , site of the 1159 conclave The cardinals assembled in the
Vatican Basilica on 4 September, three days after the death of Adrian IV. They had decided that, according to the custom, the election should be unanimous to be valid. It seems that the candidature of Bernard of Porto, recommended by Adrian as acceptable for both factions, had never been even advanced. Both parties put forward candidates mutually unacceptable: the imperial party proposed Ottaviano de Monticelli, while "Sicilians" proposed chancellor Rolando. The cardinals discussed for three days without achieving a compromise. However, the "Sicilian" party was able to join all the neutral cardinals and probably detached also some members of the imperial faction. On the fourth day (7 September), Cardinal Rolando of Siena was proclaimed pope by them and took the name Alexander III, although the unanimity had not been achieved and some cardinals still opposed his candidature. However, the version of the imperial cardinals is believed to be less reliable than the version of the Alexandrine party, even if the latter may be also not fully accurate; based on the subscriptions of the manifests of both parties issued shortly after the election, it is possible to assume that at least twenty-three electors voted for Rolando, and no more than six opposed him.
Election of Victor IV The electors of Cardinal Rolando, immediately after proclaiming him Pope, attempted to place upon him the purple mantle which symbolized the assumption of the papal office, but then the election entered the tumultuous stage. Cardinal Ottaviano Monticelli snatched the mantle from Alexander's back and his armed bands burst into the basilica. Alexander III and his supporters fled to the citadel of St. Peter, which was in the hands of Cardinal
Boso. In their absence, the few cardinals who remained in basilica elected Ottaviano of S. Cecilia to the papacy and enthroned him as Victor IV.
Consecration of Alexander III Pope Alexander III remained in the citadel for a week until he was rescued and escorted from Rome by
Odo Frangipane, and on September 18 he was eventually bestowed with the purple mantle. On 27 September he excommunicated Victor IV and his adherents.
Consecration of Victor IV Victor IV was consecrated on 4 October in the
abbey of Farfa by Cardinal-Bishop
Imar of Tusculum, dean of the Sacred College of Cardinals, assisted by the bishops
Ubaldo of Ferentino and
Riccardo of Melfi. With the armed assistance of Otto von Wittelsbach and his own armed groups in relatively short time he took control over the City of Rome and the Patrimony of St. Peter, while Alexander III took refuge in the territory of the
Kingdom of Sicily, and later in
France.
Manifests of both factions in October 1159 Both rivals together with their adherents defended the legality of their elections. In October 1159 cardinals of both obediences produced the manifests to the Emperor Frederick in favour of their elects. The “Alexandrine” manifest was subscribed by twenty three cardinals, while that of Victorine faction only by five. Supporters of Victor IV, admitting that they were in minority, justified their action by the fact that the opposite faction broke the rule of unanimity and – in consequence – the election of Rolando was invalid. The opposite party claimed that the principle of unanimity had been breached by the obstructive conduct of merely three cardinals of the Imperial faction, who stubbornly refused to recognize the candidate desired by the rest of the Sacred College. Raymond of S. Maria in Vi Lata did the same between February and April 1160. Besides, at the end of 1159 Victor IV created at least three new cardinal-deacons: Bernard of SS. Sergio e Bacco, Giovanni of S Maria in Aquiro and
Lando of S. Angelo, while Alexander III appointed on February 18, 1160, cardinal-deacon Milo of S. Maria in Aquiro. ==Schism==
