After visiting Ravenna on his way back from Reims, Stephen had returned before the end of November 816 to Rome, where he apparently discontinued Leo III’s policies of favoring clergy over lay aristocracy.

After holding the traditional ordination of priests and bishops in December and confirming Farfa Abbey’s possessions on condition that every day the monks would recite one hundred “Kyrie Eleisons” as well as a yearly payment to the Roman Church of ten golden solidi, Stephen dies on January 24, 817.

He is buried at St. Peter’s.

At some point, Stephen will be canonized as a saint of the Catholic Church.

The abbot of Santo Stefano Rotondo, Pascale Massimi, a native of Rome and son of Bonosus and Lady Theodora, is raised to the pontificate as Paschal I by the acclamation of the clergy less than a day after the death of Pope Stephen IV.

This decision occurs before the sanction of the emperor Louis the Pious has been obtained, and in a circumstance for which it is one of his first tasks to apologize.

He advises the emperor that the decision had been made to avoid factional strife in Rome, and his papal legate Theodore supposedly returned with a document titled Pactum cum Pashali pontiff, in which the Emperor congratulated Paschal, recognized his sovereignty over the Papal States and guaranteed the free election of future pontiffs.

This document will be challenged by later historians as a forgery as Paschal’s relations with the imperial house are never cordial, and he will have no success in winning the sympathy of the Roman nobles.

The appointment of 'Ali ar-Rida arouses varying reactions—few of them, even among the Shi'ites, wholly favorable—and Iraq, already irritated by al-Ma'mun's transfer of the capital from Baghdad to Merv and by other offenses, rises up in rebellion.

In July 817, after news reaches the city that Ma'mun has chosen an Alid, Ali ibn Musa al-Rida, as his heir-apparent, the city appoints his uncle, Ibrahim, son of the third caliph, al-Mahdi, as Caliph.

A requirement of Tantric Buddhism, that rites be performed in secret but with the congregation present, leads to the development of forehalls in Tantric “kondos,” such as the one built at Koryuji in about 818.

Ashot is the son of the Iberian nobleman Adarnase who had founded the Bagratoni hereditary fiefdom in Tao-Klarjeti (now northeast Turkey) and bequeathed to his son extensive possessions acquired upon the extinction of his Guaramid and Chosroid cousins.

Ashot initially had failed to gain a foothold in central Iberia (Shida Kartli), his efforts being dashed by the Arab control of Tiflis.

Ashot has established himself in his patrimonial duchy of Klarjeti, where he has restored the castle of Artanuji said to have been built by the Iberian king Vakhtang I Gorgasali in the fifth century, and received imperial protection, being recognized as the presiding prince and curopalates of Iberia.

To revive a country devastated by the Arabs and cholera epidemics, he patronized the local monastic communities established by Grigol Khandzteli, and encouraged the settlement of the Georgians in the region.

As a result, the political and religious center of Iberia is effectively transferred from central Iberia to the southwest, in Tao-Klarjeti.

From his base in Tao-Klarjeti, Ashot fights to recover more Georgian lands from the Arab hold and, though not always successful, succeeds in taking much of the adjoining lands from Tao in the southwest to Shida Kartli in the northeast, including Kola, Artani, Javakheti, Samtskhe, and Trialeti.

Of the former Chosroid possessions, only Kakheti to the east eludes him.

With local Arab emirs in the Caucasus growing ever more independent, the Caliph recognizes Ashot as the prince of Iberia in order to counter the rebellious emir of Tiflis Isma’il ibn Shu’aib around 818.

The emir had enlisted support of Ashot’s foe—the Kakhetian prince Grigol—and the Georgian highland tribes of Mtiulians and Tsanars.

Ashot, joined by Constantinople’s vassal king of Abasgia, Theodosius II, meets the emir on the Ksani, winning a victory and pushing the Kakhetians from central Iberian lands.

Al-Hakam crushes a rebellion led by clerics in the suburb (“arrabal” in Spanish; hence the incident’s name “Revolt of the Arrabal”) of al-Ribad on the south bank of the Guadalquivir river in 818.

The rebels storm the palace in March, but the palace guards slaughter the attackers.

Some three hundred of the suburb’s notables are captured and crucified.

The emir’s troops sack the suburb and demolish it, expelling the rest of its approximately sixty thousand inhabitants from Spain.

Some move to Alexandria in Egypt, some to Fez and Crete.

Others join the Levantine pirates.

The Revolt of Bernard of Italy and His Surrender (817)

In 817, Louis the Pious issues the Ordinatio Imperii, a decree intended to regulate the succession of the Frankish Empire and prevent dynastic fragmentation. The ordinance formally designates Lothair I, Louis’ eldest son, as co-emperor, while his younger sons Pepin and Louis the German receive Aquitaine and Bavaria as subordinate kingdoms.

However, the Ordinatio Imperii places Bernard of Italy, Charlemagne’s illegitimate grandson and ruler of the Kingdom of Italy, in an uncertain and subordinate position. Though still nominally King of Italy, Bernard is now clearly subordinate to Lothair I, threatening his autonomy. Upon learning of this development, Bernard begins plotting for independence, fearing the gradual absorption of his kingdom into the empire.

Louis the Pious’ Swift Response

Louis, learning of Bernard’s discontent and suspected rebellion, acts decisively. Instead of allowing time for Bernard to gather support, Louis mobilizes his army immediately and marches toward Italy. By moving swiftly, he prevents Bernard from organizing an effective resistance.

Stopping at Chalon-sur-Saône, Louis sends an invitation to Bernard, offering him a meeting. Realizing he is outmatched and unprepared for war, Bernard, intimidated by the emperor’s rapid action, has no choice but to surrender at Chalon.

This surrender, however, will not save him from Louis' wrath, as the emperor seeks to eliminate any potential challenge to his authority. What follows is one of the most tragic episodes of Louis the Pious' reign.

Bernard is taken to Aachen by Louis, who here has him tried and condemned to death for treason.

Louis has the sentence commuted to blinding, which is duly carried out; Bernard does not survive the ordeal, however, dying after two days of agony.

Others also suffer: Theodulf of Orléans, in eclipse since the death of Charles, is accused of having supported the rebellion, and is thrown into a monastic prison, where he dies soon after—poisoned, it is rumored.

The fate of his nephew will deeply mark Louis's conscience for the rest of his life.

A number of the exiled Córdoban revolutionaries sail to Alexandria and take control here until their expulsion, to Crete, in 827.

Many of the unsuccessful Spanish Muslim participants in the 818 “Revolt of the Arrabal” emigrate from Córdoba to North Africa to settle in Fés.

The vizier had been assassinated in February 818 during al-Fadl’s long journey from Merv to Baghdad, and 'Ali ar-Rida dies in August 818, after a brief illness, at Tus. (Shi'ite historians attribute his death to poison, possibly administered by the caliph himself. His shrine (mashhad) at Tus becomes a pilgrimage place and gives its name to the city Mashhad, or Meshed. The Shi'ites attribute many miracles to 'Ali ar-Rida.)
