A 1.2% growth of carbon-14 concentration recorded in tree rings suggests that a very strong radiation burst may have hit the earth in either 774 or 775.

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.)

Mediterranean Southwest Europe (772–783 CE): Charlemagne's Conquest and the End of Lombard Rule

The era 772–783 CE in Mediterranean Southwest Europe is dominated by Charlemagne’s decisive conquest of the Lombard Kingdom, fundamentally altering Italy's political landscape and setting the stage for a new imperial epoch under Frankish rule.

Charlemagne's Lombard Campaign

In 774 CE, Charlemagne, King of the Franks, successfully completes his campaign against the Lombards by capturing their capital, Pavia. His victory results in the deposition of Lombard King Desiderius and marks the definitive end of independent Lombard power in Italy. Charlemagne assumes the title King of the Lombards, integrating the Lombard territories into his expanding Frankish empire.

End of Lombard Autonomy and Regional Realignment

With Charlemagne’s conquest, the political autonomy the Lombards had enjoyed for over two centuries effectively ceases. The integration of the Lombard kingdom into Charlemagne’s dominion reshapes Italy’s political structure, reducing the influence of local Lombard elites and enhancing Frankish administrative control.

Strengthened Papal-Frankish Alliance

The conquest further consolidates the historic alliance between the papacy and the Frankish monarchy, initiated by Pepin the Short. Charlemagne reaffirms papal territorial claims, reinforcing the temporal authority of the Papal States and solidifying a powerful political and religious partnership central to medieval European politics.

Continued Mozarab Cultural Evolution in Iberia

In Iberia, Mozarab communities persist under stable Islamic governance, particularly in cultural hubs like Córdoba, Seville, and Toledo. These communities continue adapting culturally, blending their Latin-Christian traditions with the Arabic and Islamic influences of their Moorish rulers, further enriching the Iberian cultural landscape.

Technological and Economic Development

Technological advancements, particularly in metallurgy following the introduction of the Catalan forge, continue to enhance regional economic productivity. Increased iron production supports broader economic prosperity, facilitating improvements in agriculture, military technology, and craftsmanship throughout the region.

Legacy of the Era

The era 772–783 CE marks a transformative moment in Mediterranean Southwest Europe. Charlemagne’s conquest ends Lombard rule, reshapes Italy’s political map, and fortifies the papal-Frankish alliance. These developments lay the groundwork for the emergence of the Carolingian Empire, profoundly influencing the region’s medieval trajectory.

North Africa (772–783 CE)

Muhallabid Prosperity, Berber State Flourishing, and Regional Autonomy

Between 772 and 783 CE, North Africa experiences a period marked by continued Muhallabid administration in Ifriqiya, the consolidation of indigenous Berber states, and economic vibrancy driven by flourishing trade networks. This era showcases both Arab administrative achievements and the expanding independence of Berber political entities across the Maghreb.

From their base in Kairouan (Al Qayrawan), the Muhallabid dynasty, governors appointed by the Abbasid caliphs in Baghdad, maintain a largely autonomous but effective rule over Ifriqiya. Under Muhallabid stewardship, notably from Umar ibn Hafs al-Muhallabi (appointed governor in 771 CE), the region witnesses significant agricultural and economic growth, fostered by major expansions in irrigation and infrastructure projects. This economic revitalization secures relative prosperity and stability in Ifriqiya, despite persistent Berber discontent and sporadic uprisings along the periphery.

Concurrently, the Rustamid Dynasty, firmly established in the central Maghreb at Tahert (Tiaret) under Ibadi Kharijite principles, continues to mature into a prominent center of scholarship, religious learning, and trade. Its position as an elective imamate promoting justice and intellectual exchange significantly enhances its reputation, attracting merchants, scholars, and settlers across the region. Rustamid governance, recognized for its integrity and fairness, provides a stable alternative to direct Abbasid or Muhallabid control, further strengthening Berber regional autonomy.

Further west, in what is now Morocco, the Barghawata confederation consolidates its independent political and religious identity, combining indigenous Berber traditions with a unique interpretation of Islam. The city-state of Sijilmasa, strategically located on lucrative trans-Saharan trade routes controlled primarily by influential Tuareg tribes, similarly continues to thrive as a prosperous and autonomous economic hub, bolstered by flourishing trade connections with sub-Saharan Africa.

Despite their local successes, the Muhallabids in Ifriqiya find their regional authority constrained. They maintain stable governance within their immediate jurisdiction, but their ability to project power westward is limited. They remain unable to impede the solidification of independent states like the Rustamids, Barghawata, or the emergent Arab-led Idrisid Dynasty, founded by Idris I in 788 CE, whose early formation and influence begin to take shape toward the end of this era.

By the close of 783 CE, North Africa stands defined by a diverse political and economic mosaic. Muhallabid prosperity in Ifriqiya contrasts with—and exists alongside—the robust independence of increasingly influential Berber-led states. This dynamic blend of central stability and peripheral autonomy sets the stage for subsequent periods of vibrant regional interplay and cultural synthesis.

Atlantic Southwest Europe (772–783 CE): Asturian Territorial Stability and Internal Consolidation

Between 772 and 783 CE, Atlantic Southwest Europe—encompassing Galicia, northern and central Portugal, Asturias, Cantabria, and northern Spain south of the Franco-Spanish border (43.05548° N, 1.22924° W)—entered a period marked by internal consolidation and relative political stability under the Asturian monarchy. The reigns of King Aurelius (768–774 CE) and his successor, King Silo (774–783 CE), reinforced regional governance, economic resilience, and ecclesiastical authority, firmly embedding the Asturian kingdom’s political and cultural identity within the broader context of ongoing Christian resistance against Islamic al-Andalus.

Political and Military Developments

Aurelius and Diplomatic Consolidation
King Aurelius’s reign (768–774 CE) emphasized diplomatic stability, effectively easing internal tensions following Fruela I’s tumultuous rule. He prioritized internal harmony through strategic alliances and cautious diplomacy, solidifying cooperative relationships with regional aristocrats, tribal leaders, and influential bishops. This diplomatic approach ensured stable governance and continued support for central Asturian authority.

Silo’s Reign and Political Stability
Following Aurelius’s death, King Silo (774–783 CE) maintained this strategy of internal consolidation. His marriage to Adosinda, daughter of King Alfonso I, strengthened royal legitimacy and reinforced dynastic continuity. Silo concentrated primarily on internal governance rather than aggressive territorial expansion, ensuring regional unity, securing Asturian borders, and maintaining stable diplomatic relations with neighboring Vascones and Galician nobility.

Economic Developments

Economic Stability and Moderate Growth
The relative internal stability of Aurelius’s and Silo’s reigns enabled steady economic progress. Regional villa-based agriculture continued prospering, particularly in grain production, vineyards, olive cultivation, and livestock husbandry. Mining activities—especially gold and silver extraction in Galicia and Asturias—remained economically significant, bolstering regional prosperity.

Sustained Maritime and Regional Commerce
Coastal towns such as Bracara Augusta (Braga) and smaller ports along Galicia and northern Portugal maintained modest but consistent maritime trade networks. These trade connections linked Atlantic Southwest Europe with broader North Atlantic and Mediterranean markets, supporting sustained economic continuity.

Cultural and Religious Developments

Strengthening of Ecclesiastical Institutions
Influential bishoprics—especially Braga, Lugo, Iria Flavia, and Asturica Augusta—continued reinforcing their roles as central civic and administrative authorities. Bishops provided critical social leadership, fostering education, administering local justice, and deeply embedding orthodox Christian practices into community life.

Monastic Expansion and Cultural Preservation
Monastic communities expanded steadily, serving as key cultural and educational centers. Monasteries actively preserved manuscripts, promoted literacy and scholarship, fostered agricultural innovation, and provided crucial social welfare. Their influence significantly shaped regional cultural identity and resilience.

Continued Cultural Syncretism
The persistent blending of orthodox Christianity with indigenous Celtic and Iberian traditions continued robustly, particularly in rural and mountainous regions like Galicia, Asturias, and northern Portugal. This enduring cultural synthesis reinforced local identities, ensuring cultural continuity and regional cohesion.

Civic Identity and Governance

Increasing Centralization with Continued Regional Autonomy
Under Aurelius and Silo, Asturian governance became gradually more centralized, yet still respected considerable local autonomy. Civic identities increasingly coalesced around Asturian royal authority and ecclesiastical leadership, clearly establishing the kingdom as the nucleus of Iberian Christian resistance and cultural unity.

Notable Tribal Groups and Settlements

• Astures and Cantabri: Provided critical political and military stability, reinforcing Asturian governance structures and regional cohesion.

• Galicians and Lusitanians: Maintained effective local governance, economic stability, and cultural autonomy, cooperating pragmatically with Asturian authority.

• Vascones: Continued their longstanding political neutrality, territorial independence, and cultural distinctiveness, largely insulated from broader Iberian conflicts, though maintaining diplomatic relations with Asturias.

Long-Term Significance and Legacy

Between 772 and 783 CE, Atlantic Southwest Europe:

• Experienced internal consolidation and diplomatic stability under Asturian royal authority, reinforcing regional cohesion and political unity.

• Sustained resilient economies, ecclesiastical institutions, and strong local governance structures, shaping the medieval social and political fabric.

• Preserved distinctive regional cultural identities, laying lasting foundations for the development of enduring medieval Iberian societies.

This era solidified the internal structures and cultural identity of the Asturian kingdom, decisively influencing Atlantic Southwest Europe’s medieval historical trajectory.
