The Extent of Muslim Conquests by 875 CE

By 875 CE, Muslim conquests have expanded dramatically, stretching from Spain in the west to the Indus Valley in the east.

• In the west, Al-Andalus remains under Umayyad rule, centered in Córdoba.
• In North Africa, the Aghlabids control much of the region, while Idrisid Morocco remains independent.
• In the east, the Abbasid Caliphate governs vast territories, with its influence extending deep into Persia and Central Asia.
• Muslim expansion reaches the Indus Valley, incorporating Sindh into the Islamic world and solidifying Islamic influence in South Asia.

This period marks the height of early Islamic territorial expansion, establishing an interconnected Muslim world spanning three continents.

The Lavish Manuscripts of Charles the Bald (860s–870s): The Revival of Figurative Painting

During the 860s and 870s, a series of extraordinarily decorated manuscripts were commissioned by Charles the Bald, grandson of Charlemagne, from an unidentified scriptorium. These manuscripts mark a high point of Carolingian art, as their artists:

• Freely borrow from Late Antique, Byzantine, Insular, and Italian artistic traditions, creating a richly eclectic style.
• Reintroduce figurative painting and pictorial narrative to northern Europe, bridging the gap between the classical world and the medieval age.
• Use elaborate gold and silver leaf, combined with vivid colors and intricate calligraphy, to produce some of the most luxurious manuscripts of the early medieval period.

Stylistic Influences

1. Late Antiquity → Borrowing from Roman imperial art, these manuscripts feature illusionistic depth, naturalistic drapery, and architectural framing, reviving pictorial realism.
2. Byzantine Art → The use of gold backgrounds, stylized figures, and elaborate decoration echoes Byzantine icon painting and mosaics.
3. Insular Traditions (British Isles) → The intricate interlace patterns, ornamental initials, and carpet pagesreflect influences from Northumbrian and Irish monasteries.
4. Italian Renaissance Precursors → Elements of early Carolingian classicism, inspired by manuscripts preserved in Rome and Ravenna, help bridge Late Antiquity and medieval book illumination.

Key Manuscripts from the 860s–870s

• Codex Aureus of St. Emmeram (c. 870, Bayerische Staatsbibliothek, Munich) → Featuring a gold and gem-encrusted cover, it exemplifies the opulence of Carolingian manuscript art.
• Vivian Bible (c. 846, Bibliothèque nationale de France, Paris) → A grand, illuminated Bible presented to Charles the Bald at Tours, with narrative biblical imagery.
• Psalter of Charles the Bald (c. 860, Bibliothèque nationale de France, Paris) → A richly illustrated psalter with classical figures and detailed architectural settings.
• Lothair Crystal (9th century, British Museum, London) → While not a manuscript, this carved rock crystal disk commissioned in the Carolingian court exemplifies the visual storytelling techniques seen in manuscripts.

Impact on European Art

• These manuscripts redefine book illumination, merging northern European, Byzantine, and Roman influences into a new visual language.
• The artistic innovations of Charles the Bald’s court influence the Ottonian and Romanesque manuscript traditions, ensuring the continuation of pictorial narrative and classical imagery in later medieval Europe.
• They help establish Charles the Bald’s court as a leading center of cultural patronage, reinforcing Carolingian authority through artistic grandeur.

The manuscripts of the 860s and 870s commissioned by Charles the Bald represent a culmination of Carolingian artistic achievement, reviving figurative painting and setting the stage for the flourishing of medieval manuscript illumination in the centuries to come.

East Central Europe (868–879 CE): Moravian Cultural Flourishing, Carolingian-Slavic Conflict, and Saxon Dynastic Consolidation

Between 868 and 879 CE, East Central Europe—comprising modern-day Poland, Czechia, Slovakia, Hungary, and eastern portions of Germany and Austria east of 10°E and north of a line from approximately 48.2°N at 10°E to the Austro-Slovenian border near 46.7°N, 15.4°E—witnessed a dynamic interplay of cultural innovation, political realignment, and military tensions. Great Moravia under Rastislav and later his nephew Svatopluk I reached new cultural and political heights. Concurrently, tensions between Carolingian East Francia and Slavic principalities intensified, while Saxon noble families, notably the Liudolfing dynasty, continued to solidify their power, setting the stage for future imperial ascendancy.

Political and Military Developments

Great Moravia: From Rastislav to Svatopluk

• After the deposition of Rastislav by his nephew Svatopluk I in 870 CE, Great Moravia reached its political apex, effectively resisting Carolingian influence and expanding its territories through strategic military campaigns and diplomatic alliances.

Conflict and Accommodation with Carolingian East Francia

• Conflicts between Moravian and East Frankish forces intensified, highlighted by significant military engagements and shifting alliances. The complex diplomatic interplay resulted in temporary truces and territorial adjustments, reshaping the regional balance of power.

Consolidation of Liudolfing Saxony

• In Saxony, the Liudolfing dynasty, led by Otto the Illustrious (d. 912), continued consolidating power, enhancing territorial governance, establishing dynastic prestige, and laying the groundwork for their later imperial significance.

Economic and Technological Developments

Flourishing Trade and Regional Prosperity

• Trade networks connecting Moravia, Saxony, Bavaria, and Thuringia remained vibrant, facilitating extensive commerce in metals, textiles, livestock, and luxury goods, further promoting regional economic stability and growth.

Advances in Fortification and Infrastructure

• Increased regional tensions led to enhanced investment in fortifications, roads, and administrative infrastructure, significantly improving defensive capabilities and economic integration across Moravian, Saxon, and Carolingian territories.

Cultural and Artistic Developments

Moravian Cultural Renaissance

• Great Moravia flourished culturally, notably through the missionary activities of Cyril and Methodius, who further promoted the Glagolitic script and Slavic liturgy, deeply embedding Moravia’s distinct Slavic cultural and religious identity.

Saxon Cultural Integration and Carolingian Influence

• The Liudolfing dynasty reinforced Saxon cultural integration into the Carolingian sphere through ecclesiastical foundations, artistic patronage, and adoption of Frankish administrative customs, solidifying Saxony’s prominence within East Francia.

Settlement and Urban Development

Expansion of Moravian Political and Ecclesiastical Centers

• Major Moravian urban centers, such as Mikulčice and Nitra, expanded significantly, serving as key political, administrative, cultural, and religious hubs for Great Moravia’s growing influence.

Stable Growth in Saxon and Bavarian Towns

• Urban settlements in Saxony and Bavaria remained stable, experiencing growth driven by strong economic networks, effective administration, and continued integration into East Francia’s political framework.

Social and Religious Developments

Strengthened Christian Identity in Moravia

• Cyril and Methodius’s missions deepened Christianity’s roots across Moravia, fostering a distinctly Slavic Christian tradition and strengthening ecclesiastical institutions, profoundly shaping Moravia’s social and religious fabric.

Dynastic Power and Social Structure Consolidation

• The continued ascendancy of the Liudolfing dynasty in Saxony and the Mojmirid rulers in Moravia reinforced hierarchical social structures, forming clear patterns of medieval governance and aristocratic power that endured for centuries.

Long-Term Consequences and Historical Significance

The period 868–879 CE proved transformative for East Central Europe, marked by the cultural and political ascendancy of Great Moravia under Rastislav and Svatopluk, escalating tensions with Carolingian East Francia, and the solidification of Saxon Liudolfing dynastic power. These developments significantly shaped regional identities, political structures, and cultural traditions, profoundly influencing the historical trajectory of East Central Europe through the ensuing medieval era.

The Moravian duke Svatopluk creates the Slavic Kingdom of Great Moravia.

Louis the German, King of East Francia, exercises some limited authority over the Slav tribes east of the Elbe River.

A new dynasty, which comes to be called Macedonian, takes the throne of the East Roman Empire in 867, and its forces soon begin to roll back the tide of Islamic expansion.

Antioch, Syria, Georgia, and Armenia are reconquered.

The military conquests of the Macedonian Dynasty initiate a period of economic growth and prosperity and a cultural renaissance.

Agriculture flourishes as conditions stabilize and, as emperors increasingly use land grants to reward military service, the area under cultivation expands.

The prosperity of improved agricultural conditions and the export of woven silk and other craft articles allowed the population to grow.

Expanding commercial opportunities increase the influence of the nearby Italian maritime republics of Venice, Genoa, and Amalfi, which eventually gain control of the Mediterranean trade routes into Greece.

The extension of Greek interests to the Adriatic raises again the question of imperial claims to South Italy and, indeed, to the entire western part of the old Roman Empire.

The physical separation of that empire into East and West had been emphasized by the settlement of the Slavs in the Balkan Peninsula and in Greece, and since the seventh century, the two worlds have developed in their different ways.

Their differences have been manifested in ecclesiastical conflicts, such as the Photian Schism.

The conversion of the Slavs has produced bitterness between the agents of the rival jurisdictions, but the reestablishment of imperial authority in Greece and eastern Europe, added to the gains against the Muslim powers in Asia, reinforces Constantinople’s belief in the universality of the empire, to which Italy and the West must surely be reunited in time.

The fiction is maintained that, until this time comes, the rulers of western Europe, like those of the Slavs, hold their authority by virtue of their special relationship with the one true emperor in Constantinople.

Creation of figural art once more becomes important in the churches in 843 after the return to power of the “icon lovers,” as they are called.

Eastern Southeast Europe (868–879 CE): Byzantine Renaissance and Religious Expansion

Settlement and Migration Patterns

Continued Stability and Cultural Integration

From 868 to 879 CE, Eastern Southeast Europe maintained regional stability and settlement patterns. The period experienced ongoing cultural integration and demographic cohesion, further strengthened by significant political and religious developments.

Political and Military Developments

Macedonian Dynasty and Territorial Reconquests

A new ruling house, the Macedonian Dynasty, ascended the throne of the Byzantine Empire in 867 CE, initiating a revival of Byzantine power. The dynasty’s forces successfully began reclaiming territories previously lost to Islamic expansion, including Antioch, Syria, Georgia, and Armenia, marking a significant resurgence of imperial strength and territorial integrity.

Byzantine Territorial Ambitions

The extension of Greek influence towards the Adriatic revived Byzantine ambitions regarding South Italy and the Western territories of the old Roman Empire. Although practical authority remained limited, Constantinople continued to assert a theoretical claim over these regions, reflecting sustained imperial aspirations of universal rule.

Economic and Technological Developments

Economic Growth and Prosperity

Military successes of the Macedonian Dynasty initiated a period of notable economic prosperity. Agriculture flourished due to stabilizing conditions and increased cultivation driven by land grants awarded for military service. Additionally, trade growth, particularly in woven silk and crafts, expanded economic opportunities and supported population increases.

Influence of Italian Maritime Republics

Expanding trade enhanced the economic influence of Italian maritime republics—Venice, Genoa, and Amalfi. These republics increasingly dominated Mediterranean trade routes into Greece, significantly affecting regional economic dynamics.

Cultural and Artistic Developments

Revival of Figural Art

After 843 CE, the return of the "icon lovers" significantly revitalized figural art within Byzantine churches. This era experienced a flourishing of religious iconography and related artistic endeavors, becoming an integral part of the broader Byzantine cultural renaissance.

Scholarly and Literary Revival

The Macedonian Renaissance fostered increased scholarly activity, marked by expanded manuscript production in scriptoria and renewed interest in classical and theological studies. This intellectual flourishing significantly reinforced cultural resilience and continuity.

Social and Religious Developments

Photian Schism and Ecclesiastical Rivalries

The Photian Schism underscored ongoing tensions between the sees of Rome and Constantinople, primarily centered around jurisdictional authority rather than doctrinal differences. Despite resolution, these disputes influenced regional religious dynamics, intensifying competition for ecclesiastical control in Bulgaria and the wider Balkans.

Conversion and Cultural Integration of the Slavs

The conversion of Slavic peoples significantly impacted Eastern Southeast Europe's religious landscape. Orthodox missionaries, notably Cyril and Methodius, successfully proselytized Bulgaria, Serbia, and eventually Russia. Bulgaria’s acceptance of Eastern Rite Christianity and the establishment of an autocephalous Bulgarian Church in 870 CE permanently united Bulgarian and Slavic cultures through the literary and religious frameworks developed by Cyril and Methodius.

Long-Term Consequences and Historical Significance

The period from 868 to 879 CE witnessed the significant military, economic, cultural, and religious revival under the Macedonian Dynasty, profoundly reshaping Eastern Southeast Europe's historical trajectory. Territorial reconquests, economic prosperity, ecclesiastical dynamics, and the cultural integration of the Slavs had lasting impacts on regional stability and identity, reinforcing Constantinople’s claims to universal empire.

Local Slav chiefs in the area of present Romania have apparently entered into a vassal relationship with the Bulgarian tsars, who, following the conversion of Boris I to Christianity in 864, serve as religious and cultural intermediaries between Dacia and the Empire.

Rome and Constantinople compete for political and cultural influence in Bulgaria.

Orthodox missionaries, including Cyril and Methodius, lead the proselytization of Bulgaria, Serbia, and eventually Russia.

The Eastern Empire wins in 870 when Bulgaria accepts Eastern Rite (Orthodox) Christianity and an autocephalous Bulgarian Church is established.

This decision opens Bulgaria to Byzantine culture (and territorial ambitions) through the literary language devised for the Slavs by Cyril and Methodius.

Establishment of a common, official religion also permanently joins the Bulgarian and Slavic cultures.
