Pope Boniface III was the bishop of Rome from 19 February 607 to his death on 12 November of the same year. Despite his short pontificate, he made a significant contribution to the Catholic Church.
Pope Gregory II was the bishop of Rome from 19 May 715 to his death. His defiance of Emperor Leo III the Isaurian as a result of the iconoclastic controversy in the Eastern Empire prepared the way for a long series of revolts, schisms, and civil wars that eventually led to the establishment of the temporal power of the popes.
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 a 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 Constantine was the bishop of Rome from 25 March 708 to his death. One of the last popes of the Byzantine Papacy, the defining moment of his pontificate was his 710/711 visit to Constantinople, where he compromised with Justinian II on the Trullan canons of the Quinisext Council. The city's next papal visit occurred in 1967.
Pope John V was the bishop of Rome from 23 July 685 to his death on 2 August 686. He was the first pope of the Byzantine Papacy consecrated without prior imperial consent, and the first in a line of ten consecutive popes of Eastern origin. His papacy was marked by reconciliation between the city of Rome and the Empire.
Pope John X was the bishop of Rome and nominal ruler of the Papal States from March 914 to his death. A candidate of the counts of Tusculum, he attempted to unify Italy under the leadership of Berengar of Friuli, and was instrumental in the defeat of the Saracens at the Battle of Garigliano. He eventually fell out with Marozia, who had him deposed, imprisoned, and finally murdered. John’s pontificate occurred during the period known as the Saeculum obscurum.
Pope Conon was the bishop of Rome from 21 October 686 to his death. He had been put forward as a compromise candidate, there being a conflict between the two factions resident in Rome — the military and the clerical. He consecrated the Irish missionary St Kilian and commissioned him to preach in Franconia.
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.
The Duchy of Spoleto was a Lombard territory founded about 570 in central Italy by the Lombard dux Faroald. Its capital was the city of Spoleto.
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.
According to Roman Catholicism, 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.
The Duchy of Rome was a state within the Byzantine Exarchate of Ravenna. Like other Byzantine states in Italy, it was ruled by an imperial functionary with the title of dux. The duchy often came into conflict with the Papacy over supremacy within Rome. After the founding of the Papal States in 756, the Duchy of Rome ceased to be an administrative unit and 'dukes of Rome', appointed by the popes rather than emperors, are only rarely attested.
The selection of the Pope, the Bishop of Rome and Supreme Pontiff of the Catholic Church, prior to the promulgation of In Nomine Domini in AD 1059 varied throughout history. Popes were often putatively 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 putative jus exclusivae, i.e., the claimed but invalid right to veto the selection that Catholic monarchs exercised into the twentieth century.
Toto was the self-styled duke of Nepi, the leading magnate of Etruria, who staged a coup d'état in Rome in 767. He became Duke of Rome for a year until his death. The principal sources documenting his takeover are the vita of Pope Stephen III in the Liber Pontificalis and a surviving deposition of the primicerius Christopher from 769, preserved in a ninth-century manuscript of Verona, the Depositio Christophori.
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 their episcopal consecration, and many popes were chosen from the apocrisiarii or the inhabitants of Byzantine-ruled Greece, Syria, or Sicily. Justinian I reconquered 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.
The Lateran Council of 649 was a synod held in the Basilica of St. John Lateran to condemn Monothelitism, a Christology espoused by many Eastern Christians, and Pope Honorius. The Council did not achieve ecumenical status in either East or West, but represented the first attempt of a pope to convene an ecumenical council independent of the Roman emperor.
From 756 to 857, the papacy shifted from the influence 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 Placidia Palace was the official residence of the papal apocrisiarius, the ambassador from the pope to the patriarch of Constantinople, and the intermittent home of the pope himself when in residence at Constantinople. The apocrisiarius held "considerable influence as a conduit for both public and covert communications" between pope and Byzantine emperor.
The apocrisiarius or apocrisiary was the legate from the pope to the patriarch of Constantinople, circa 452–743, equivalent to the modern nunciature.
