Pope Celestine IV, born Goffredo da Castiglione, was head of the Catholic Church and ruler of the Papal States for only a few days from 25 October 1241 to his death in 10 November 1241.
Pope Gregory X, born Teobaldo Visconti, was head of the Catholic Church and ruler of the Papal States from 1 September 1271 to his death and was a member of the Secular Franciscan Order. He was elected at the conclusion of a papal election that ran from 1268 to 1271, the longest papal election in the history of the Catholic Church.
Pope Nicholas III, born Giovanni Gaetano Orsini, was head of the Catholic Church and ruler of the Papal States from 25 November 1277 to his death on 22 August 1280.
Sede vacante is a term for the state of a diocese while without a bishop. In the canon law of the Catholic Church, the term is used to refer to the vacancy of the bishop's or Pope's authority upon his death or resignation.
A papal conclave is a gathering of the College of Cardinals convened to elect a bishop of Rome, also known as the pope. Catholics consider the pope to be the apostolic successor of Saint Peter and the earthly head of the Catholic Church.
In the papal conclave held from 14 to 16 June 1846, Giovanni Maria Mastai Ferretti was elected to succeed the recently deceased Gregory XVI as pope. He took the name Pius IX and had the longest pontificate since Saint Peter.
The papal conclave held from 18 to 20 February 1878 saw the election of Vincenzo Pecci, who took the name Leo XIII as pope. Held after the death of Pius IX, who had had the longest pontificate since Saint Peter, it was the first election of a pope who would not rule the Papal States. It was the first to meet in the Apostolic Palace in the Vatican because the venue used earlier in the 19th century, the Quirinal Palace, was now the palace of the king of Italy, Umberto I.
Jus exclusivae was the right claimed by several Catholic monarchs of Europe to veto a candidate for the papacy. Although never formally recognized by the Catholic Church, the monarchs of France, Spain and Austria claimed this right at various times, making known to a papal conclave, through a crown-cardinal, that the monarch deemed a particular candidate for the papacy objectionable.
Carlo de' Medici was the son of Ferdinando I de' Medici, Grand Duke of Tuscany and Christina of Lorraine.
Hugh of Evesham was a 13th-century English churchman, physician and alchemist. Given his name, it is likely that he came from Evesham, Worcestershire.
The 1492 papal conclave was convened after the death of Pope Innocent VIII. It was the first papal conclave to be held in the Sistine Chapel.
The 1268–71 papal election, 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", that is, by the appointment of 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 removed the roof of the Palazzo dei Papi di Viterbo where the election took place.
The 1406 papal conclave, the papal conclave of the time of the Great Western Schism, convened after the death of Pope Innocent VII. It elected Cardinal Angelo Correr, who under the name of Gregory XII became the fourth pope of the Roman Obedience.
The papal conclave held from 16 to 18 December 1352 was convened after the death of Pope Clement VI and elected as his successor Cardinal Etienne Aubert. The fifth pope of the period of the Avignon Papacy, he took the name Innocent VI. This conclave is remarkable because during its celebration cardinals for the first time in history subscribed the electoral capitulation, which limited the power of elect.
The January 1276 papal conclave, was the 1st papal conclave. held under the rules of constitution Ubi periculum issued by Pope Gregory X in 1274, which established papal conclaves. According to Ubi periculum Cardinals were to be secluded in a closed area; they were not even accorded separate rooms. No cardinal was allowed to be attended by more than one servant unless ill. Food was to be supplied through a window; after three days of the meeting, the cardinals were to receive only one dish a day; after five days, they were to receive just bread and water. During the conclave, no cardinal was to receive any ecclesiastical revenue. These provisions were regularly disregarded, at the discretion of the cardinals, particularly the requirement of being incommunicado.
The 1241 papal election saw the election of 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 and the Lombard League and deceased pontiff, Pope Gregory IX, with Italy divided between pro-Papal and pro-Imperial factions known as the Guelphs and Ghibellines.
The 1294 papal conclave was convoked in Naples after the resignation of Pope Celestine V on 13 December 1294. Celestine V had only months earlier restored the election procedures set forth in the papal bull Ubi periculum of Pope Gregory X, which had been suspended by Pope Adrian V in July 1276. Every papal election since then has been a papal conclave. It was the first papal conclave held during the lifetime of the preceding pontiff, an event not repeated until the 2013 papal conclave following the resignation of Pope Benedict XVI.
Ubi periculum is a papal bull promulgated by Pope Gregory X during the Second Council of Lyon on 7 July 1274 that established the papal conclave format as the method for selecting a pope, specifically the confinement and isolation of the cardinals in conditions designed to speed them to reach a broad consensus. Its title, as is traditional for such documents, is taken from the opening words of the original Latin text, Ubi periculum maius intenditur, 'Where greater danger lies'. Its adoption was supported by the hundreds of bishops at that council over the objections of the cardinals. The regulations were formulated in response to the tactics used against the cardinals by the magistrates of Viterbo during the protracted papal election of 1268–1271, which took almost three years to elect Gregory X. In requiring that the cardinals meet in isolation, Gregory was not innovating but implementing a practice that the cardinals had either adopted on their own initiative or had forced upon them by civil authorities. After later popes suspended the rules of Ubi periculum and several were elected in traditional elections rather than conclaves, Pope Boniface VIII incorporated Ubi periculum into canon law in 1298.
In the papal conclave held from 8 to 16 May 1605 Cardinal Camillo Borghes was elected to succeed Leo XI as pope. Borghes took the name Paul V. This was the second conclave of 1605, with the one that had elected Leo XI having concluded just 37 days earlier. It is significant for having the only recorded case of an injury at a papal conclave, which was the result of a physical fight amongst the cardinals over who should be elected pope.
The 1243 papal election elected Cardinal Sinibaldo Fieschi of Genoa to succeed Pope Celestine IV. The conclave began after the Holy See had been vacant for 18 months and six days, therefore ca. May 16, 1243. There were nine cardinals present. Six votes were needed, therefore, for a canonical election. It took some five weeks for the cardinals to agree on an acceptable candidate. Fieschi took the name Innocent IV.
