Question: The papal election of 1159 followed the death of which pope, who ruled from 1154 until 1159?

full_context: Document 1: Papal election, 1061: The papal election of 1061 was held on 30 September 1061 in San Pietro in Vincoli ("Saint Peter in Chains") in Rome, following the death of Pope Nicholas II. In accordance with Nicholas II's bull, "In Nomine Domini", the cardinal bishops were the sole electors of the pope for the first time in the history of the Roman Catholic Church. Bishop Anselmo de Baggio of Lucca, a non-cardinal and one of the founders of the Pataria, was elected Pope Alexander II and crowned at nightfall on 1 October 1061 in San Pietro in Vincoli Basilica because opposition to the election made a coronation in St. Peter's Basilica impossible.
Document 2: Papal election, 1159: The Papal election of 4–7 September 1159 followed the death of Pope Adrian IV. It resulted in a double election. A majority of the cardinals elected Cardinal Rolando of Siena as Pope Alexander III, but a minority refused to recognize him and elected their own candidate Ottaviano de Monticelli, who took the name Victor IV, creating a schism which lasted until 1178.
Document 3: Papal election, 1268–71: The papal election from November 1268 to September 1, 1271, following the death of Pope Clement IV, was the longest papal election in the history of the Catholic Church. This was due primarily to political infighting between the cardinals. The election of Teobaldo Visconti as Pope Gregory X was the first example of a papal election by "Compromise." The election was effected by a Committee of six cardinals agreed to by the other remaining ten. The election occurred more than a year after the magistrates of Viterbo locked the cardinals in, reduced their rations to bread and water, and legendarily removed the roof of the Palazzo dei Papi di Viterbo.
Document 4: Nicholas Kanabos: Nicholaus Kanabus was elected Emperor of the Byzantine Empire during the 4th Crusade on 25 or 27 January 1204 by an assembly of the Byzantine Senate, priests, and the mob of Constantinople in direct opposition to co-emperors Isaac II and Alexios IV. Nicholaus was a young noble (probably a relative of Angelid emperors) who was chosen after three days of sorting through several unwilling candidates and refused to assume the lofty position. Though popularly chosen, he never accepted imperial power, and took Sanctuary in the bowels of Hagia Sophia. Alexios V "Mourtzouphlos", who had deposed Emperors Isaac II and Alexios IV, offered him a prominent position in his own administration, but Nicholaus adamantly rejected these terms. On February 8, after rebuffing an imperial summons, Emperor Nicholaus Kanabus was dragged out of the church, in which he had sought refuge, and strangled on the ornate marble steps of Hagia Sophia.
Document 5: Papal election, 1292–94: The papal election from April 5, 1292 to July 5, 1294 was the last papal election which did not take the form of a papal conclave (in which the electors are locked in seclusion "cum clave"—Latin for "with a key"—and not permitted to leave until a new Bishop of Rome has been elected). After the death of Pope Nicholas IV on April 4, 1292, the eleven surviving cardinals (a twelfth died during the "sede vacante") deliberated for more than two years before electing the third of six non-cardinals to be elected pope during the Late Middle Ages: Pietro da Morrone, who took the name Pope Celestine V.

Document 7: Papal election, 1241: The papal election, following the death of Pope Gregory IX, from September 21 to October 25, 1241 elected Cardinal Goffredo da Castiglione as Pope Celestine IV. The election took place during the first of many protracted "sede vacantes" of the Middle Ages, and like many of them was characterized by disputes between popes and the Holy Roman Emperor. Specifically, the election took place during the war between Frederick II, Holy Roman Emperor against the Lombard League and the deceased pontiff, Pope Gregory IX, with Italy divided between pro-Papal and pro-Imperial factions known as the Guelphs and Ghibellines.
Document 8: Johannes Hymonides: Johannes Hymonides, known as John the Deacon of Rome (d. between 876 and 882), was a deacon of the Roman Church. Few details are known of his life: after the death of St Nicholas I, he was briefly exiled from Rome at the behest of the emperor Louis II, but was recalled by Adrian II. Possessed of considerable learning, he was closely associated with Anastasius, Librarian of the Roman Church (died 879).
Document 9: Archdeacon George of the Cross: Archdeacon George (Geevarghese) of the cross was the son of the elder brother of Archdeacon Geevarghese of Christ. By the last year of Bishop Mar Abraham, he became the Archdeacon. After the death of Persian Bishop Mar Abraham in 1597, he led the Indian Church. He led the church amidst Portuguese intervention. The synod of Diamper 1599 was held during his time. In 1601 Francis Roz became Bishop appointed by Menezis of Goa. In the beginning there was cordiality. But the deliberate downgradation of Angamaly and the inertia of Bishop Roz frustrated him. When the Archdeacon protested, Roz ex-communicated him. In 1615 Bishop and Archdeacon reconciled each other, but again fell out later. The next Bishop Britto also did not recognize the Archdeacon's ecclesiastical status. He led the church in a period of severe stress turmoil. He led the church in a period of severe stress and held it together. After his time and his brother's time the root family of Pakalomattam became heirless. The only son shifted residence to Alappatt house. He is believed to have been buried in the forefront of Pakalomattam Thravadu (Kuravilangadu).
Document 10: Papal election, 1181: The papal election of 1181 followed the death of Pope Alexander III and resulted in the election of Pope Lucius III.

Document 11: Edward the Confessor: Edward the Confessor (Old English: "Ēadƿeard Andettere" ] , Latin: "Eduardus Confessor" ] ; c. 1003 – 5 January 1066), also known as Saint Edward the Confessor, was among the last Anglo-Saxon kings of England. Usually considered the last king of the House of Wessex, he ruled from 1042 to 1066.
Document 12: Papal election, 1154: The papal election of 1154 followed the death of Pope Anastasius IV and resulted in the election of Pope Adrian IV, the only Englishman to become pope.
Document 13: Papal election, 1243: The election which took place around the death of Pope Gregory IX on August 22, 1241, was a particularly stressful one. There were military operations, both inside and outside the City of Rome, towns and properties were destroyed, Guelphs and Ghibellines warred against each other, and two of the cardinals were captured in battle and were held prisoner by the Emperor Frederick II. When the electoral meeting began, only ten of the twelve cardinals participated. The cardinals were tightly confined, on orders of the Senator of Rome, Matteo Rosso Orsini, and during that conclave one cardinal died. After seven weeks of deadlocked negotiations in the summer heat of Rome, the cardinals finally managed to produce the required two-thirds majority on October 25 for Cardinal Goffredo Castiglione, who chose the name Celestine IV. Pope Celestine was never crowned. It is also said that he was never consecrated, which is pointless, since he was already a bishop, and that he never issued a bull, which is contested. He died, old and ill, only seventeen days after his election, on November 10, 1241.
Document 14: Elisaeus Adougan: Elisaeus Adougan was a late 14th century and early 15th century Scottish cleric. His name has been said to have occurred for the first time in a papal letter datable to 25 November 1390, but this letter is simply a repetition of another addressed to him, dated 2 August that year; both letters address him as the rector of the parish church of Kirkmahoe, and authorise him to take up the position of provost of the Collegiate Church of Lincluden providing he resigned Kirkmahoe within a period of two years.
Document 15: Pietro di Miso: Pietro di Miso (died September 17, 1174) was Italian cardinal. He was elevated to the cardinalate by Pope Adrian IV in the consistory of February 1158. Initially he was cardinal-deacon of S. Eustachio, but in 1166 he was promoted to the order of cardinal-priests and received "titulus" San Lorenzo in Damaso. After the double papal election in 1159 he supported the obedience of Pope Alexander III and served as his legate in Hungary. He signed the papal bulls between April 24, 1158 and July 17, 1174.
