The Moorish occupation of Narbonne had ended in 759 after four decades, during which time the Jewish population had greatly increased.

Jews play a pivotal role in the formal occupation of the city by Charlemagne, who grants them a third of the town under their own ruler (nasi).

Pope Stephen III complains to the Bishops of Narbonne and Septimania about the Frankish kings allowing Jews to own land.

Stephen had continued throughout 769 and 770 to rely on the support and advice of Christophorus and Sergius who had placed him on the papal throne.

Their antipathy towards the Lombards and general pro-Frankish stance causes King Desiderius to engineer their downfall.

He bribed the Papal Chamberlain, Paulus Afiarta, and other members of the papal court to spread rumors about them to the pope.

When Desiderius attempts to enter Rome in 771 with an army, claiming to be on a pilgrimage to pray at the shrine of St. Peter, Christophorus and Sergius shut the gates of the city against them.

Arriving at the gates and seeing armed troops manning the walls, the Lombard king asks to speak to the Pope, who comes out to him.

During Stephen’s absence, Afiarta and his supporters seek to stir up a mob to overthrow Christophorus and Sergius, but the Primicerius and his son gain the upper hand, and force Afiarta and his colleagues to flee to the Lateran Palace.

Stephen had by this stage returned to the Lateran, and he is confronted in the Basilica of St. Theodore by the fleeing Afiarta and his co-conspirators being chased by Christophorus and his supporters.

Apparently at this point, a suspicious Christophorus, believing that Stephen had entered into some agreement with Desiderius, forces Stephen into taking an oath that he will not turn Christophorus or his son over to the Lombards.

After this, a furious Stephen berates Christophorus, demands he stop harassing Afiarta, and orders him and his followers to withdraw, to which Christophorus complies.

Stephen flees the next day to St. Peter’s Basilica to seek the protection of Desiderius.

The Lombard king, shutting Stephen up in his suites in the Basilica, makes it clear to the Pope that the price for his help is to be the handing over of Christophorus and Sergius.

The Pope sends two bishops to negotiate with Christophorus and Sergius, telling them that they must either retire to a monastery or come out to him at St. Peter’s.

A message is sent at the same time from Desiderius to the people of the city, declaring that Pope Stephen has bid them to expel Christophorus from the city and save themselves from harm.

This message from the Lombard king has the desired effect; Christophorus and Sergius begin to suspect their associates, who in turn rapidly abandon them.

Both are reluctant to leave the city, but eventually both make their way to the Pope during the night.

The next day, Stephen is allowed to return to the city, while Christophorus and Sergius are left in Lombard hands.

Negotiations to secure their release are unsuccessful, and before the day was out, Afiarta arrives with his partisans.

After discussing the situation with Desiderius, they have both men blinded.

Christophorus dies after three days, while Sergius is kept in a cell in the Lateran.

Desiderius, in an attempt to forestall the potential intervention of Charlemagne has Stephen write a letter to the Frankish king, wherein he declares that Christophorus and Sergius had been involved in a plot with an envoy of Charlemagne’s brother, Carloman, to kill the Pope.

Further, that Stephen had fled to Desiderius for protection, and that eventually Christophorus and Sergius were brought out against their will.

While Stephen managed to save their lives, later a group of men had them blinded, but not on Stephen’s orders.

He then concludes that if it wasn’t for “his most excellent son Desiderius”, he would have been in fatal danger, and that Desiderius had reached an agreement with him to restore to the Church all the lands which she had claims on that were still in Lombard hands.

That such a letter was a fiction is demonstrated very soon after; when Stephen asks Desiderius to fulfill the promises he had made over the body of Saint Peter, the Lombard king responds:

”Be content that I removed Christophorus and Sergius, who were ruling you, out of your way, and ask not for rights. Besides, if I do not continue to help you, great trouble will befall you. For Carloman, king of the Franks, is the friend of Christophorus and Sergius, and will be wishful to come to Rome and seize you.”

Desiderius continues to stir trouble in Italy; in 771, he manages to persuade the bishops of Istria to reject the authority of the Patriarch of Grado, and to have them place themselves under the Patriarch of Aquileia, which is directly under Lombard control.

Stephen writes to the rebellious bishops, suspending them and ordering them to place themselves once again under the authority of Grado, or face excommunication.

Carloman dies on December 4, 771, at the villa of Samoussy, and Charles seizes his late brother’s territories.

Carloman’s heirs, including his widow, Gerberga, his widow, take refuge among the Lombards, sheltered by Desiderius, who then asserts independence for Lombardy, currently a vassal of both the papacy and the Frankish kingdom.

An angered Charles divorces his Lombard queen and consolidates control of the territories wrested from his late brother’s family.

She has no known children and her ultimate fate is unknown.

East Central Europe (772–783 CE): Carolingian Expansion, Saxon Resistance, and Slavic State Consolidation

Between 772 and 783 CE, East Central Europe—encompassing Poland, Czechia, Slovakia, Hungary, and those portions of Germany and Austria lying east of 10°E and north of a line stretching from roughly 48.2°N at 10°E southeastward to the Austro-Slovenian border near 46.7°N, 15.4°E—entered a pivotal period marked by the rise of Carolingian influence under Charlemagne, intensified Saxon resistance to Frankish expansion, and continued political maturation of Slavic principalities. The Avar Khaganate remained internally stable yet increasingly wary of Carolingian power, while Thuringia maintained its practical autonomy, though increasingly under pressure from the west.

Political and Military Developments

Carolingian Conquests and Saxon Resistance

• Beginning in 772 CE, Charlemagne initiated campaigns to subdue the Saxons east of the Rhine and Elbe rivers, triggering fierce resistance and ongoing military conflicts that dramatically reshaped regional political dynamics in eastern Germany and western Poland.

Continued Bavarian Influence over Slavic Territories

• Bavaria maintained its established protectorate over Carantania, continuing to wield significant political influence and integrating the region economically and culturally, despite the increasing pressures of Carolingian expansion.

Consolidation of Slavic States

• Slavic principalities, particularly in Bohemia and Moravia, further solidified governance structures, clearly defining territorial boundaries and developing effective defensive strategies against external threats, preparing for future encounters with Frankish and Carolingian influence.

Thuringian Autonomy under Carolingian Pressure

• Thuringian rulers preserved autonomy yet faced increasing diplomatic and military pressure from the expanding Carolingian Empire, signaling an imminent change in their independent status.

Avar Diplomatic Caution

• The Avar Khaganate maintained internal stability but increasingly adopted cautious diplomatic relations, recognizing the rising Carolingian threat and potential regional instability resulting from Frankish–Saxon conflicts.

Economic and Technological Developments

Economic Prosperity Amid Conflict

• Despite military conflicts, regional economic networks remained active, sustaining trade exchanges among Saxon, Slavic, Bavarian, Thuringian, Avar, and Frankish communities, including agricultural goods, iron, precious metals, textiles, and luxury items.

Expansion of Fortifications and Military Infrastructure

• Ongoing conflicts prompted significant investment in defensive fortifications and military infrastructure by Saxon, Slavic, Bavarian, and Avar communities, enhancing regional security and technological sophistication.

Cultural and Artistic Developments

Increased Frankish–Germanic Influence

• Carolingian and Saxon military interactions introduced new Germanic cultural influences across eastern Germany, Poland, and western Slavic territories, reflected archaeologically through evolving burial customs, weaponry, and metalworking styles.

Slavic Cultural Distinction

• Bohemian and Moravian Slavic communities reinforced their distinct cultural identities, evident through differentiated archaeological finds, artistic styles, ceramics, jewelry, and settlement patterns.

Avar Artistic Continuity

• The Avars maintained their distinct cultural traditions, prominently influencing regional decorative arts, jewelry, metalworking techniques, and equestrian equipment.

Settlement and Urban Development

Urban Expansion under Saxon and Frankish Influence

• Saxon settlements, despite ongoing conflicts, continued their growth, reinforcing existing fortified towns and forming the basis of later medieval urban centers within eastern Germany and adjacent areas.

Slavic Administrative and Urban Growth

• Bohemian and Moravian urban centers expanded in response to growing political stability and economic activity, laying important groundwork for the medieval era.

Stability in Bavarian and Thuringian Settlements

• Bavarian-influenced Carantania and autonomous Thuringian territories continued enjoying relative economic stability, though increasingly influenced by Carolingian expansion and Saxon–Frankish conflicts.

Social and Religious Developments

Heightened Military Aristocracies

• Ongoing Saxon–Carolingian conflicts emphasized the role of warrior aristocracies among Saxon, Bavarian, and Frankish societies, reinforcing hierarchical social structures and military prowess.

Strengthened Slavic Leadership

• Slavic principalities in Bohemia and Moravia continued centralizing leadership, improving governance, administrative efficiency, and defensive capabilities amid growing external pressures.

Continued Stability of Avar Society

• The Avars retained stable societal structures, maintaining internal cohesion through effective elite governance and careful diplomacy.

Long-Term Consequences and Historical Significance

The era 772–783 CE marked a transformative phase for East Central Europe, characterized by Charlemagne's aggressive eastward expansion, persistent Saxon resistance, and reinforced Slavic state formation. These events significantly reshaped regional power dynamics, preparing the ground for subsequent Carolingian dominion and dramatically influencing the medieval political, cultural, and economic trajectory of the region.

The Saxon Wars are the campaigns and insurrections of the more than thirty years from 772, when Charlemagne first enters Saxony with the intent to conquer, to 804, when the last rebellion of disaffected tribesmen is crushed.

Emperor Constantine V, whose military achievements make him enormously popular despite his persecution of monks who oppose his iconoclastic position, consolidates imperial power. (In later centuries, the folk of Constantinople will stand by his tomb, seeking his aid against whatever enemy imperils the city's defenses.)
