Pope Anastasius IV, born Corrado Demetri della Suburra, was head of the Catholic Church and ruler of the Papal States from 8 July 1153 to his death. He is the most recent pope to take the name "Anastasius" upon his election.
Antipope Boniface VII, otherwise known as Franco Ferrucci, was a Catholic prelate who claimed the Holy See in 974 and from 984 until 985. A popular tumult compelled him to flee to Constantinople in 974; he carried off a vast treasure, and returned in 984 and removed Pope John XIV (983–984) from office. He is supposed to have put Pope Benedict VI to death. After a brief second rule, he died under suspicious circumstances. He is today considered an antipope.
Pope Stephen III was the bishop of Rome and ruler of the Papal States from 7 August 768 to his death. Stephen was a Benedictine monk who worked in the Lateran Palace during the reign of Pope Zachary. In the midst of a tumultuous contest by rival factions to name a successor to Pope Paul I, Stephen was elected with the support of the Roman officials. He summoned the Lateran Council of 769, which sought to limit the influence of the nobles in papal elections. The Council also opposed iconoclasm.
Pope Sergius I was the bishop of Rome from 15 December 687 to his death, and is revered as a saint by the Roman Catholic church. He was elected at a time when two rivals, Paschal and Theodore, were locked in dispute about which of them should become pope. His papacy was dominated by his response to the Quinisext Council, the canons of which he steadfastly refused to accept. Thereupon Emperor Justinian II ordered Sergius' arrest, but the Roman people and the Italian militia of the exarch of Ravenna refused to allow the exarch to bring Sergius to Constantinople.
Pope Sergius II was the bishop of Rome and ruler of the Papal States from January 844 to his death in 847. Sergius II's pontificate saw the Arab raid against Rome as well as the city's redevelopment.
Pope Sergius III was the bishop of Rome and nominal ruler of the Papal States from 29 January 904 to his death. He was pope during a period of violence and disorder in central Italy, when warring aristocratic factions sought to use the material and military resources of the papacy. At the behest of Theophylact I of Tusculum, Sergius seized the papal throne from Antipope Christopher, who in turn had deposed Pope Leo V. Sergius' reign was subsequently marked by Theophylact's influence. As pope, Sergius continued many ecclesiastical controversies of his predecessors, including conflict over Pope Formosus' legacy, annulling all ordinations made by the late pope, and the filioque controversy with eastern patriarchs. His pontificate was similarly marked by temporal conflicts, with Sergius' refusal to crown Berengar I of Italy as Holy Roman Emperor, and his support of Byzantine Emperor Leo VI the Wise's fourth marriage. Sergius also saw the restoration of the Lateran Palace.
Pope Innocent II, born Gregorio Papareschi, was head of the Catholic Church and ruler of the Papal States from 14 February 1130 to his death in 1143. His election as pope was controversial and the first eight years of his reign were marked by a struggle for recognition against the supporters of Anacletus II. He reached an understanding with King Lothair III of Germany who supported him against Anacletus and whom he crowned as Holy Roman emperor. Innocent went on to preside over the Second Lateran council.
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.
Pope Nicholas II, otherwise known as Gerard of Burgundy, was the head of the Catholic Church and ruler of the Papal States from 24 January 1059 until his death. At the time of his election, he was bishop of Florence. During his Papacy, Nicholas II successfully expanded the influence of the papacy in Milan and southern Italy. He was also responsible for passing papal election reforms which resulted in greater papal influence in electing new Popes.
Antipope Constantine II was a Roman prelate who claimed the papacy from 28 June 767 to 6 August 768. He was overthrown through the intervention of the Lombards and tortured before he was condemned and expelled from the Church during the Lateran Council of 769.
Saeculum obscurum was a period in the history of the Papacy during the first two-thirds of the 10th century, beginning with the installation of Pope Sergius III in 904 and lasting for sixty years until the death of Pope John XII in 964. During this period, the popes were influenced strongly by a powerful and allegedly corrupt aristocratic family, the Theophylacti, and their relatives and allies. The era is seen as one of the lowest points of the history of the Papal office.
Antipope Philip was an antipope who held office for just one day, on 31 July 768.
Sylvester IV, born Maginulf, was a claimant to the Papacy from 1105 to 1111 in opposition to Paschal II. A priest before his election, he was probably a native of Rome. He had the backing of the Roman militia and initially of the Holy Roman Emperor, Henry IV, who later forced him to abdicate. Today he is regarded as an antipope.
Theodore was a rival with Paschal for the papacy following the death of Pope Conon, and thus is considered an antipope of the Roman Catholic church.
Paschal was a rival with Theodore for Pope following the death of Pope Conon, and thus is considered an antipope of the Roman Catholic church.
The history of the papacy, the office held by the pope as head of the Catholic Church, spans from the time of Peter to the present day. Moreover, many of the bishops of Rome in the first three centuries of the Christian era are obscure figures. Most of Peter's successors in the first three centuries following his life suffered martyrdom along with members of their flock in periods of persecution.
The selection of the pope, the bishop of Rome and supreme pontiff of the Roman Catholic Church, prior to the promulgation of In nomine Domini in 1059 varied throughout history. Popes were often appointed by their predecessors or by political rulers. While some kind of election often characterized the procedure, an election that included meaningful participation of the laity was rare, especially as the popes' claims to temporal power solidified into the Papal States. The practice of papal appointment during this period would later result in the jus exclusivae, i.e., a right to veto the selection that Catholic monarchs exercised into the twentieth century.
The Byzantine Papacy was a period of Byzantine domination of the Roman papacy from 537 to 752, when popes required the approval of the Byzantine Emperor for episcopal consecration, and many popes were chosen from the apocrisiarii or the inhabitants of Byzantine-ruled Greece, Syria, or Sicily. Justinian I conquered the Italian peninsula in the Gothic War (535–554) and appointed the next three popes, a practice that would be continued by his successors and later be delegated to the Exarchate of Ravenna.
From 756 to 857, the papacy shifted from the orbit of the Byzantine Empire to that of the kings of the Franks. Pepin the Short, Charlemagne, and Louis the Pious had considerable influence in the selection and administration of popes. The "Donation of Pepin" (756) ratified a new period of papal rule in central Italy, which became known as the Papal States.
The Lateran Council of 769 was a synod held in the Basilica of St. John Lateran to rectify perceived abuses in the papal electoral process which had led to the elevation of the antipopes Constantine II and Philip. It also condemned the rulings of the Council of Hieria. It is perhaps the most important Roman council held during the 8th century.
