Pope John X

Pope John X (Latin: Ioannes X; died 28 May 928) 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.

[3] He was made a deacon by Peter IV, the bishop of Bologna, where he attracted the attention of Theodora, the wife of Theophylact I of Tusculum, the most powerful noble in Rome.

[5] Liutprand of Cremona alleged that John became her lover during a visit to Rome;[6] However, Johann Peter Kirsch says, "This statement is, however, generally and rightly rejected as a calumny.

During his eight years as archbishop, John worked hard with Sergius in an unsuccessful attempt to depose Louis the Blind and have Berengar of Friuli, who claimed the Kingdom of Italy, crowned emperor in his stead.

[3] He also had to defend himself from a usurper who tried to take his episcopal see away, as well as confirming his authority over Nonantola Abbey when the abbot attempted to free it from the jurisdiction of the archbishop of Ravenna.

[8] After the death of Pope Lando in 914, a faction of the Roman nobility, headed by Theophylact of Tusculum, summoned John to Rome to assume the vacant papal chair.

[9] Since switching sees was considered an infraction of canon law, as well as contravening the decrees of the Lateran Council of 769, which prohibited the installation of a pope without election, John’s appointment was criticised by his contemporaries.

Meanwhile, Berengar brought with him troops from the northern parts of Italy, and the campaign was coordinated by John X, who took to the field in person, alongside Duke Alberic I of Spoleto.

There, at the Battle of Garigliano, the allies proceeded to lay siege to them for three months, at the end of which the Saracens burnt their houses and attempted to burst out of the encirclement.

With John leading the way, all were eventually caught and killed, achieving a great victory and removing the ongoing Saracen threat on the Italian mainland.

[15] So in December 915, Berengar approached Rome, and after being greeted by the family of Theophylact (whose support he secured), he met Pope John at St. Peter’s Basilica.

In 920, he was asked by the Byzantine Emperors Romanos I and Constantine VII and the Patriarch of Constantinople Nicholas Mystikos to send some legates to Constantinople to confirm the acts of a synod which condemned fourth marriages (a legacy of the conflict which embroiled Constantine’s father Leo VI the Wise) thereby ending a schism between the two churches.

He wrote to Tomislav, "king (rex) of the Croats", and to Duke Michael of Zahumlje, asking them to follow the instructions as articulated by John’s legates.

[26] Around the same time, Tsar Simeon I of Bulgaria made overtures to John, offering the renounce his nation’s obedience to the Patriarch of Constantinople, and place his kingdom under the ecclesiastical authority of the popes at Rome.

As to how far, inasmuch as they are uncultured, and but novices in the faith, they are to be subjected to severe canonical penances for their relapsing, killing of priests, and sacrificing to idols, we leave to your judgment to decide, as no one will know better than you the manners and customs of this people.

[34] He then wrote to King Rudolph of France, as well as local bishops and counts, with instructions to restore to Cluny the property of which Guido, abbot of Gigny Abbey, had taken without permission, and to put the monastery under their protection.

[48] While according to Louis Marie DeCormenin, John was: "The son of a nun and a priest... more occupied with his lusts and debauchery than with the affairs of Christendom... he was ambitious, avaricious, an apostate, destitute of shame, faith and honour, and sacrificed everything to his passions; he held the Holy See about sixteen years, to the disgrace of humanity.

"[49] However, in recent times, his pontificate has been re-evaluated, and he is now seen as a man who attempted to stand against the aristocratic domination of the papacy, who promoted a unified Italy under an imperial ruler, only to be murdered for his efforts.

He wrote: "John X, however, the man whose sins are known only by report, whose great qualities are conspicuous in history, stands forth amid the darkness of the time as one of the most memorable figures among the Popes.
