East Central Europe (736–747 CE): Saxon Dominance, Bavarian Expansion, Slavic Consolidation, and Persistent Regional Stability

Between 736 and 747 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—underwent substantial political developments. Saxon tribes consolidated control east of the Elbe River, while emerging Slavic principalities in Bohemia and Moravia continued evolving toward stable state structures. Significantly, the Duchy of Bavaria, though nominally under Frankish influence, expanded its authority eastward by establishing a protectorate around 743 CE over the Slavic principality of Carantania (modern-day Carinthia and Slovenia). This Bavarian expansion created a strategic buffer, effectively separating the southern Slavs from their northern and eastern kin. Meanwhile, the Avar Khaganatemaintained internal stability, and Thuringia preserved its autonomy amid declining Merovingian power.

Political and Military Developments

Bavarian Protectorate over Carantania (743 CE)

• Around 743 CE, responding to a request from Carantanian Prince Boruth for protection against Avar incursions, Duke Odilo of Bavaria established a protectorate over Carantania.

• This political move extended Bavarian influence deeply into Slavic territories, strategically dividing the southern Slavic tribes from their relatives to the north and east, altering long-term regional geopolitical dynamics.

Concurrent Saxon dominance, Slavic political consolidation, ongoing Thuringian independence, and sustained Avar stability collectively created foundational patterns influencing the medieval historical trajectory of the region.

Pemmo had come to the duchy of Friuli at a time when a recent civil war had ravaged the land.

Pemmo has raised all the children of the many nobles killed in the war in his own household next to his own sons.

He has also waged three wars with the Slavs of Carinthia, defeating them so utterly the third time hat they had entered into a peace treaty.

Pemmo had also quarreled with Callistus, Patriarch of Aquileia, who had been at odds with the bishop of Cividale and had removed him.

Pemmo, in response, had arrested the patriarch.

For this, King Liutprand had descended on Friuli and appointed Ratchis, Pemmo's son, in his place.

Pemmo had fled with his followers, but his son secured his pardon.

Pemmo dies in 739, leaving two other sons by Ratperga: Ratchait and Aistulf, who becomes king.

Odilo vassalizes the formerly independent Slavic princes of Carantania (roughly corresponding with the later March of Carinthia), who have asked him for protection against the invading Avars, in 745.

The era 820–831 CE was crucial for East Central Europe, defined by Great Moravia’s rise as a central Slavic power, the consolidation of Saxon nobility under Liudolfing leadership, and sustained Carolingian frontier stability. Collectively, these developments significantly shaped the region’s political structures, cultural identities, and territorial cohesion, profoundly influencing the medieval trajectory of East Central Europe.

The many tribes—Danes, Obotrites, Slovenes, Bretons, Basques—that inhabit the frontier lands at the start of the reign of Louis the German over Eastern Francia had remained in awe at the power of the Frankish emperor and dared not stir up any trouble.

The Sorbs in 818 had rebelled, however, and had been quickly followed by Slavomir, chief of the Obotrites, who had been captured and abandoned by his own people, being replaced in 818 by Ceadrag.

Soon, Ceadrag too had turned against the Franks and allied with the Danes, who will shortly become the greatest menace of the Franks.

A greater Slavic menace is gathering on the southeast, where, Ljudevit Posavski, the Croat Prince of Savia from about 810, is harassing the border at the Drava and Sava rivers.

As the ruler of the Pannonian Croats, his successful resistance of Frankish domination is an important precursor to the eventual unification of Croatian duchies in Dalmatia and Pannonia into the Kingdom of Croatia.

The margrave of Friuli, Cadolah, had been sent out against him, but he had died on campaign and in 820 his margarvate had been invaded by Slovenes.

An alliance had been made in 821 with Borna, duke of Dalmatia, and in 822 Ljudevit is brought to heel.

After being forced to flee, Ljudevit becomes a ruler over the Serbs, maintaining close ties with the Carantanians and Timokians (the Slavs, or Vlachs, in the Timok River valley).
