Pope Sergius III (c. 860 − 14 April 911) was Pope from 29 January 904 to his death in 911. He was pope during a period of feudal violence and disorder in central Italy, when warring aristocratic factions sought to use the material and military resources of the Papacy. [1] Because Sergius III had reputedly ordered the murder of his two immediate predecessors, Leo V and Christopher, and allegedly fathered an illegitimate son who later became pope (John XI), his pontificate has been variously described as "dismal and disgraceful", [2] and "efficient and ruthless". [3]

Pope leader of the Catholic Church

The pope, also known as the supreme pontiff, is the bishop of Rome and ex officio leader of the worldwide Catholic Church. Since 1929, the pope has also been head of state of Vatican City, a city-state enclaved within Rome, Italy. The current pope is Francis, who was elected on 13 March 2013, succeeding Benedict XVI.

Feudalism combination of legal and military customs in medieval Europe

Feudalism was a combination of legal and military customs in medieval Europe that flourished between the 9th and 15th centuries. Broadly defined, it was a way of structuring society around relationships derived from the holding of land in exchange for service or labour. Although derived from the Latin word feodum or feudum (fief), then in use, the term feudalism and the system it describes were not conceived of as a formal political system by the people living in the Middle Ages. In its classic definition, by François-Louis Ganshof (1944), feudalism describes a set of reciprocal legal and military obligations among the warrior nobility revolving around the three key concepts of lords, vassals and fiefs.

Pope Leo V pope

Pope Leo V was Pope from July 903 to his death in 904. He was pope during the period known as the Saeculum obscurum. He was thrown into prison in September 903 by the Antipope Christopher, and was probably killed at the start of the pontificate of Pope Sergius III. If his deposition is not considered valid, then his papacy may be considered to have ended with his death in 904.


Early career

Sergius was the son of Benedictus, [4] and traditionally was believed descended from a noble Roman family, although it has been speculated that he was in fact related to the family of Theophylact, Count of Tusculum. He was ordained as a subdeacon by Pope Marinus I, followed by his being raised to the deaconate by Pope Stephen V. [5] During the pontificate of Pope Formosus (891–896), he was a member of the party of nobles who supported the Emperor Lambert, who was the opponent of Formosus and the pope's preferred imperial candidate, Arnulf of Carinthia. [6] Formosus consecrated Sergius as bishop of Caere (Cerveteri) in 893, apparently in order to remove him from Rome. [7] Sergius ceased to act as bishop of Caere with the death of Formosus in 896, as all of the ordinations conferred by Formosus were declared null and void, [8] although Formosus’ ordination of Sergius was later reconfirmed by Theodore II. [9] He also actively participated in the farcical Cadaver synod that condemned the pontificate of Formosus. [10]

Subdeacon is a title used in various branches of Christianity.

Pope Marinus I pope

Pope Marinus I was Pope from 16 December 882 until his death in 884. He succeeded John VIII from around the end of December 882.

Pope Stephen V pope

Pope Stephen V was Pope from September 885 to his death in 891. He succeeded Pope Adrian III, and was in turn succeeded by Pope Formosus. In his dealings with Constantinople in the matter of Photius, as also in his relations with the young Slavic Orthodox church, he pursued the policy of Pope Nicholas I.

With the death of Theodore in 898, Sergius, with a small following of Roman nobility led by his father Benedictus, attempted to have himself elected pope, contrary to the wishes of the emperor Lambert, who was also duke of Spoleto. Although Sergius was actually elected, a rival candidate, Pope John IX (898–900), was also elected. [11] With Lambert's support, John was successfully installed as pope, and one of his first acts was to convene a synod which excommunicated Sergius and his followers. [12] Sergius was then forcibly exiled by Lambert, fleeing to his see at Caere, where he placed himself under the protection of Adalbert II, Margrave of Tuscany. [13]

Lambert of Italy King of Italy, Holy Roman Emperor, and Duke of Spoleto and Camerino

Lambert was the King of Italy from 891, Holy Roman Emperor, co-ruling with his father from 892, and Duke of Spoleto and Camerino from his father's death in 894. He was the son of Guy III of Spoleto and Ageltrude, born in San Rufino. He was the last ruler to issue a capitulary in the Carolingian tradition.

Duchy of Spoleto

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.

Pope John IX pope

Pope John IX was Pope from January 898 to his death in 900.

By the time the Antipope Christopher (903–904) seized the chair of Saint Peter by force, circumstances had changed at Rome, with the rise of the magister militum Theophylact, Count of Tusculum, who had been stationed at Rome by the retreating emperor Louis the Blind in 902. Putting himself at the head of a faction of the nobility, Theophylact revolted against Christopher, and asked Sergius to return to Rome to become pope. [14] Sergius accepted, and with the armed backing of Adalbert II, he entered Rome, by which stage Christopher had already been cast into prison by Theophylact. Sergius was then consecrated Pope on 29 January 904. [15]

Antipope Christopher Antipope

Christopher held the (anti)papacy from October 903 to January 904. Although he was listed as a legitimate Pope in most modern lists of Popes until the first half of the 20th century, the apparently uncanonical method by which he obtained the papacy led to his being removed from the quasi-official roster of popes, the Annuario pontificio. As such, he is now considered an antipope by the Catholic Church.

Saint Peter apostle and first pope

Saint Peter, also known as Simon Peter, Simeon, Simon, Cephas, or Peter the Apostle, was one of the Twelve Apostles of Jesus Christ, and the first leader of the early Church.

<i>Magister militum</i> position

Magister militum was a top-level military command used in the later Roman Empire, dating from the reign of Constantine the Great. Used alone, the term referred to the senior military officer of the Empire. In Greek sources, the term is translated either as strategos or as stratelates.

Sergius III owed his rise to the power of his new patron Theophylact, and rewarded him with the position of sacri palatii vestararius , the principal official at the top of papal patronage in control of the disbursements, and thus of patronage. All real power now devolved onto Theophylact, and Sergius essentially became his puppet. Perhaps the first clear sign of this shift in power was the fate of Sergius’ two predecessors, Pope Leo V and the Antipope Christopher. According to the pro-Formosan Eugenius Vulgarius, Sergius ordered both men to be strangled in prison sometime in early 904. [16] That both men were murdered during Sergius’ pontificate appears probable, although other accounts state that Christopher at least was allowed to retire to a monastery. [17] Given where the real power lay, it seems more likely that either Theophylact gave the orders directly, or that he directed Sergius to give the orders. [18] For the remainder of his pontificate, Sergius promoted his family and members of his aristocratic party to positions of authority and prominence within the church. [19]


The vestararius was the manager of the medieval Roman Curia office of the vestiarium, responsible for the management of papal finances as well as the papal wardrobe. The vestiarium is mentioned as the papal treasury as early as the seventh century, during the period of Byzantine cultural hegemony in the West called the "Byzantine Papacy", but the vestararius itself is attested to only from the eighth century.

Eugenius Vulgarius was an Italian priest and poet.

Activity in Italy

Pope Sergius III

Pope Sergius III convoked a synod which annulled all the ordinations of Formosus and required all bishops ordained by Formosus to be re-ordained. It was alleged that Sergius managed to get the consent of the Roman clergy at the synod by threatening them with exile, violence or through the use of bribery. [20] The decision to require reordination was very unpopular, and those affected at sees distant from Rome not only ignored the synod's instructions, but wrote letters both condemning the revoking of ordinations and justifying validity of the original ordinations. [21] The ruling was subsequently reversed again after his death.[ citation needed ]

Ordination religious process by which individuals are consecrated as clergy

Ordination is the process by which individuals are consecrated, that is, set apart and elevated from the laity class to the clergy, who are thus then authorized to perform various religious rites and ceremonies. The process and ceremonies of ordination vary by religion and denomination. One who is in preparation for, or who is undergoing the process of ordination is sometimes called an ordinand. The liturgy used at an ordination is sometimes referred to as an ordination.

A bishop is an ordained, consecrated, or appointed member of the Christian clergy who is generally entrusted with a position of authority and oversight.

Confirming his continued support of the anti-Formosus faction, Sergius honoured the murdered Pope Stephen VI (896–897), who had been responsible for the "Cadaver Synod" that had condemned and mutilated the corpse of Pope Formosus, by writing a laudatory epitaph on Stephen VI's tombstone. [22] For centuries it was believed that Sergius then had the much-abused corpse of Formosus exhumed once more, tried, found guilty again, and beheaded, thus in effect conducting a second Cadaver Synod. [23] However, the source for this was Liutprand of Cremona, who mistakenly placed the cadaver synod in the pontificate of Sergius III, instead of Stephen VI. [24]

Although neither Sergius nor Theophylact supported the continued nominal rule of Emperor Louis, they were somewhat unwilling to grant the imperial title to the only other contender, Berengar I of Italy. On the one occasion that Sergius agreed to crown Berengar in around 906, Berengar was prevented from reaching Rome by the forces of Alberic I of Spoleto and Adalbert II of Tuscany, both of whom had been supporters of Sergius, but were unhappy with his decision to support Berengar. Nevertheless, Berengar's unwillingness to control his vassals also contributed to the papal reluctance; when Albuinus, the Margrave of Istria began taking papal territory off John, the Archbishop of Ravenna in 907, Sergius had written to Albuinus asking for him to desist. [25] When Sergius was ignored, the pope wrote to the bishop of Pola in 910, making it clear that: ”he would never bestow the (imperial) crown on Berenger till he promised to take the (Istrian) March from Albuinus, and give it to some better man.” [26]

Sergius rebuilt the Lateran Palace, which had been shattered by an earthquake in 896, and then stripped of its treasures by the Antipope Christopher. Sergius refurbished it with objects, images and crucifixes, and decorated its newly built walls with frescos. [27] In 905 he provided funds to the Church of Silva Candida, which had been devastated by a Saracen raid. [28] He also helped with the rebuilding of Nonantola Abbey, which had suffered attacks from the Magyars, [29] and finally he granted privileges to some monasteries and churches in West and East Francia.

Relations with Constantinople

Sergius, like his predecessors, continued to defend the Filioque interpolation into the Nicene Creed, which was at odds with the position of the eastern church. Papal legates who attended the Synod of Trosle in June 909 attacked the Byzantine position, which the synod then condemned in the fourteenth canon:

As the Holy Apostolic See has made known to us that the blasphemous errors of a certain Photius against the Holy Ghost are still vigorous in the East, errors which teach that the Holy Spirit proceeds not from the Son but from the Father only we exhort you venerable brethren, together with us, in accordance with the admonition of the ruler of the Roman See, after a careful study of the works of the Fathers, to draw from the quiver of Holy Writ arrows sharp enough to slay the monster which is again springing into life. [30]

Almost a century later, this decision led to the removal of Sergius's name from the Diptychs by Patriarch Sergius II of Constantinople. [31]

However, the major issue with Constantinople that presented itself during Sergius’ pontificate was the question over the fourth marriage of the Byzantine Emperor Leo VI. Both the emperor, who wanted to marry Zoe Karbonopsina and the Patriarch of Constantinople, Nicholas Mystikos, appealed to Sergius; the pope sent papal legates to Constantinople, who confirmed the pope's ruling in favour of the emperor, on the grounds that fourth marriages had not been condemned by the Church as a whole. [32] Nicholas’ refusal to accept this ruling saw him deposed by Leo VI, upon which he too appealed to Sergius, claiming his deposition was unjustified.

Alleged affair with Marozia

Sergius’ ties with the family of Theophylact were made even closer, at least according to rumour, by Sergius’ supposed affair with Theophylact's daughter, Marozia. This relationship was promoted by Marozia's mother, Theodora, and the result of this affair was a male child who in time became Pope John XI (931–935). [33] The only source of this affair is the chronicler Liutprand of Cremona, writing some 50 years after the events of Sergius’ pontificate. Neither Auxilius of Naples nor Eugenius Vulgarius, both of whom were exact contemporaries of Sergius, and both of whom were hostile towards Sergius for his attacks on Formosus, mention this allegation at all. [34]

The affair, while not an impossibility, would certainly not have persisted beyond Marozia's marriage to Alberic I of Spoleto in 909. The question of whether Theophylact and Theodora needed to tie Sergius to them by such means, particularly when Sergius was already deeply indebted to them for his elevation to the papacy, as well as wasting Marozia in a relationship when, as the daughter of an important house, she would have been a valuable tool to link via marriage to another noble house, is open to debate. The birth of the future John XI in 910, after her marriage to Alberic, would seem to indicate that Sergius was not the father. [35] However, it was highly unusual that the eldest son of a noble house would be destined for a career in the church, instead of inheriting his father's title. That the younger brother Alberic took his father's place as duke of Spoleto, suggests the possibility that the elder brother John was illegitimate, with Sergius being the most likely candidate for his father.[ citation needed ]


Sergius III died on 14 April 911, and was succeeded by Pope Anastasius III. He was buried in the Church of St. Peter, between the Silver gate and the gate of Ravenna. [36]


Much of Sergius’ pontificate has been maligned throughout history, principally through the reporting of his character and the state of Rome at the time by Liutprand of Cremona. His recounting of the period was remarkable for the rise of what 19th century papal historians saw as a "pornocracy",[ citation needed ] or "rule of the harlots",[ citation needed ] a reversal of the natural order as they saw it, according to Liber pontificalis and a later chronicler who was also biased against Sergius III. This "pornocracy"[ citation needed ] was an age with women in power: Theodora, whom Liutprand characterized as a "shameless whore... [who] exercised power on the Roman citizenry like a man"[ citation needed ] and her daughter Marozia, the mother of Pope John XI and reputed to be the mistress of Sergius III, largely upon a remark by Liutprand.[ citation needed ]

Caesar Baronius, writing in the 16th century, and basing himself on Liutprand, was particularly scathing, describing Sergius as: ”a wretch, worthy of the rope and of fire... flames could not have caused this execrable monster to suffer the punishments which he merited. It is impossible to believe that such a pope was a lawful one.” [37]

However, the reality is that when Sergius was forcibly exiled by Lambert, duke of Spoleto, all the official records were destroyed; consequently, most of the surviving documentation about Sergius comes from his pro-Formosan opponents who had fled to Naples. [38] Horace Mann, writing in the Catholic Encyclopedia states the following concerning the alleged illicit relationship of Pope Sergius III with Marozia: "that he put his two predecessors to death, and by illicit relations with Marozia had a son, who was afterwards John XI, must be regarded as highly doubtful. These assertions are only made by bitter or ill-informed adversaries, and are inconsistent with what is said of him by respectable contemporaries." [39]

Nevertheless, most modern opinions about Sergius’ pontificate remain poor. According to Horace K. Mann, “Sergius was, unfortunately, a pronounced party-man, and anxious for the supremacy of his party.” [40]

The best that Ferdinand Gregorovius could say of him was: “That Sergius, who remained Pope throughout the storms of seven years, was at least a man of energy must be admitted, although apostolic virtues are scarcely to be looked for in a character such as his.” [41]

James S. Packer described him as malignant and ferocious, slaughtering his enemies with a private army, [42] while Walter Ullmann described Sergius as a typical representative of the House of Theophylact, concerned with power and sexual liaisons. [43]
