The kingdom of Louis the German

After his conquest of the German lands, Charlemagne administered the area like he did the rest of his kingdom, or empire (Reich), through his counts and bishops. He established his primary residence at Aachen (now in Germany), which was not far from the conquered territories, though his decision probably had more to do with the town’s hot springs than with strategic planning. His son Louis I (Louis the Pious) remained involved in the affairs of the German, Danish, and Slavic lands, but his primary focus was on the regions of his empire where the Romance, or proto-Romance, language was spoken. In 817, however, he issued the Ordinatio Imperii, an edict that reorganized the empire and established the imperial succession. As part of the restructuring, Louis awarded his young son Louis II (Louis the German; 804–876) with the government of Bavaria and the lands of the Carinthians, Bohemians, Avars, and Slavs. Becoming the king of Bavaria in 825, Louis the German gradually extended his power over all of Carolingian Germany.

Louis the German’s rise to power, however, was not a smooth one, because internal turmoil plagued the Carolingian empire in the 830s and early 840s. Although he would ultimately rescue Louis the Pious on both occasions, the younger Louis was involved in revolts against his father in 830 and 833–834. In the final settlement of the succession, Louis the German’s inheritance was restricted to Bavaria by his father, who had reconciled with his oldest son and the heir to the imperial throne, Lothar. After their father’s death, the surviving sons of Louis fell into three years of civil war, which led to the division of the Carolingian empire. During these civil wars, Louis took side with his brother Charles the Bald and confirmed this alliance in the famous Oath of Strasbourg in 842 (an important political and linguistic document that contains versions of the Romance language and Old High German). The success of Charles and Louis against their older brother Lothar led to a formal end to the civil wars in the Treaty of Verdun in 843, which divided the realm among the three leaders and laid out the rough outlines of late medieval France and Germany. In this settlement, Louis received the eastern kingdom, which included the lands east of the Rhine River (Bavaria, Franconia, Saxony, Swabia, and Thuringia).

As ruler of the eastern Frankish kingdom, Louis faced the challenge of maintaining the unity of a very diverse kingdom as well as asserting his place in the wider Carolingian world and protecting the frontiers from invaders. Like his brothers, Louis sought to establish his preeminence in the old empire. On two occasions he invaded Charles the Bald’s kingdom and on a third occasion supported the invasion of the kingdom by his son. Louis also invaded the territory of the heirs of Lothar and attempted to seize the imperial crown. Moreover, much of Louis’s reign was taken up with campaigns against neighboring Slavs. Although he faced attacks by the Slavs and Vikings and the challenge of powerful aristocratic families, Louis maintained stability and royal authority over the aristocracy as a result of his external focus. By 870 Louis’s dominions reached almost the boundaries of medieval Germany. On the east they were bordered by the Elbe and the Bohemian mountains; on the west, beyond the Rhine, they included the districts afterward known as Alsace and Lorraine. Ecclesiastically, they included the provinces of Mainz, Trier, Cologne, Salzburg, and Bremen. Although the close kinship and rivalries of the descendants of Charlemagne still united the eastern and western Frankish lands, the eastern region was taking on the identity of Germany, and the west was emerging as France.

Louis’s long reign provided a degree of unity and continuity for the peoples of his varied kingdom and also laid the foundation for developments in later medieval Germany. His appointment of his sons as subkings over regions of the kingdom foreshadowed the later territorial dukes, and his support for and reliance on monasteries prefigured the policy of the Saxon dynasty in the 10th century. In good Carolingian tradition, he promoted missionary activity in concert with his military campaigns in the east. Louis also cultivated the German language and literature for the first time as a source of self-conscious cultural and political identity. Under his patronage the Gospels were translated into German dialects, and the first attempts at writing German poetry with Christian and traditional themes were undertaken.

After his death the kingdom was divided among his three sons according to Frankish tradition, but the deaths of two of them, in 880 and 882, restored its unity under Charles III (Charles the Fat). The ceaseless attacks by Danes, Saracens, and Magyars in the later 9th and 10th centuries, however, weakened the kingdom’s cohesion and led to the creation of new kingdoms within the boundaries of the Carolingian realm. Incompetence in mounting effective resistance to invaders also led to revolts and civil wars, as for instance in 887 when Arnulf, an illegitimate son of Louis the German’s son Carloman, led an army of Bavarians in a successful revolt against his uncle, Charles the Fat. Arnulf, however, was not equally successful in defending his eastern possessions. After his death in 899, the German kingdom came under the nominal rule of the last Carolingian king of Francia Orientalis, his young son, Louis IV (Louis the Child), and in the absence of strong military leadership it became the prey of the Magyar horsemen and other invaders from the east.

Rise of the duchies

Because the Carolingians themselves were unable to provide effective defense for the whole kingdom, military command and the political and economic power necessary to support it necessarily devolved to local leaders whose regions were attacked. The inevitable result was the decentralization and decay of royal authority to the benefit of the regional dukes. Contrary to popular opinion, these dukes were not appointed by their peoples, nor were they descendants of the tribal chieftains of the postmigration period. The so-called Stammesherzogtümer (tribal duchies) were new political and, ultimately, social units. Their dukes were Carolingian counts, part of the international “imperial aristocracy” of the Carolingians, who organized defense on a local basis without questioning loyalty to the Carolingians. All the same, their initial success established them in the hearts of those whom they protected. In Saxony the Liudolfings, descendants of military commanders first established by Louis the German, achieved spectacular successes against the Slavs, Danes, and Magyars. In Franconia the Konradings rose to prominence over this largely Frankish region with the assistance of Arnulf but became largely independent during the minority of his son. Similarly, the Luitpoldings, originally named as Carolingian commanders, became dukes of Bavaria. Thuringia fell increasingly under the protection and lordship of the Liudolfings. In Swabia (Alemannia) several clans disputed control with one another and with regional ecclesiastical lords. Throughout the kingdom the only force for preserving unity remained the church, but the bishops approved the secularization of much monastic land to sustain troops who could counter the threat of external foes, thus further strengthening the power of the dukes.

The structural transformation of the “imperial aristocracy” into a local elite accompanied the emergence of an increasingly particularist, dynastically oriented aristocratic society that was bound together through ties of vassalage and in which local rulers exercised personal lordship over the free and half-free populations of the regions. This process did not advance as far in Germany as it did in France. Everywhere German society remained closer to older, regional varieties of social organization as well as to traditions of Carolingian government by ecclesiastical authorities and imperial deputies.
