The early Carolingians consolidated control over the Frankish heartland and the duchies east of the Rhine, partly by supporting the missionary activities of churchmen who espoused Roman hierarchical forms of ecclesiastical organization that favoured political centralization; looser indigenous and Irish ecclesiastical structures meanwhile lost ground. Frankish penetration followed a pattern in which communities or churches were settled on land newly won from forest or marsh and granted them by their Carolingian protectors. Thus, from Frisia in the north to Bavaria in the south, religious, economic, and political penetration went hand in hand. A distinguished part was played by Anglo-Saxon missionaries, who linked the Frankish world not only with the high culture of their homeland but also with Rome. One of the most prominent of these was Willibrord" class="md-crosslink">St. Willibrord (c. 658–739), who worked as a missionary and Frankish agent among the Frisians and later the Thuringians. Of even greater significance was Willibrord’s disciple St. Boniface (c. 675–754), the “apostle of Germany,” who preached the Word to the pagan Germans and introduced religious reform to the Frankish church. Supported by Charles Martel, Boniface led missions into Franconia, Thuringia, and Bavaria, where he founded or restructured diocesan organization on a Roman model. In 742, with the support of the new mayors of the palace Pippin and Carloman, he played a large part in the first council of the new German church. By the time of his martyrdom at the hands of northern Frisians, all the continental Germanic peoples except the Saxons were well on the way toward integration into a Roman-Frankish ecclesiastical structure.
Boniface’s missionary activities and religious reforms also influenced political developments in the Frankish kingdom. His close contact and frequent correspondence with the pope in Rome reinforced a developing trend in the Frankish world that involved the increasing devotion to St. Peter and his vicar. When Charles Martel’s son and successor, Pippin, sought justification for his usurpation of the Frankish throne in 750, he appealed to Pope Zacharias, asking whether the person with the title or the power should be king. In the following year, Pippin assumed the throne and was crowned by the bishops of his realm, including, according to one account, the pope’s representative in the Frankish kingdom, St. Boniface. Three years later, PopeStephen II" class="md-crosslink"> Stephen II traveled to Pippin’s kingdom to seek aid from the king against the Lombards. While there, Stephen strengthened the alliance with the Carolingians and Pippin’s claim to the throne when he crowned Pippin and, according to some accounts, Pippin’s sons Carloman and the future Charlemagne. Charlemagne
Charlemagne built on the foundations laid by Boniface, Charles Martel, and Pippin. Contemporary writers were vastly impressed by Charlemagne’s political campaigns to destroy the autonomy of Bavaria and his equally determined efforts against the Saxons. Under their Agilolfing dukes, who had at times led the opposition to the rising Carolingians, the Bavarians had developed an independent, southward-looking state that had close contacts with Lombard Italy and peaceful relations with the Avar kingdom to the east. Charlemagne’s conquest of the Lombards in 774 left Bavaria isolated, and in 788 Charlemagne succeeded in deposing the last Agilolfing duke, Tassilo III, and replacing him with a trusted agent. Thereafter Charlemagne used Bavaria as the staging ground for a series of campaigns in 791, 795, and 796 that destroyed the Avar kingdom.
The subjugation of the north proved much more difficult than that of the south. In the wake of the missionaries, Frankish counts and other officials moved into northeastern Frisia, raising contingents for the royal host and doing the other business of secular government. As for the Rhineland, the richer it grew, the more necessary it became to protect its hinterland, Franconia (including present-day Hessen) and Thuringia, from Saxon raids. Because there was no natural barrier behind which to hold the Saxons, this was a difficult task.
Unlike the Bavarians, the Saxons were not politically united. Their independent edhelingi (nobles) lived on estates among forest clearings, dominating the frilingi (freemen), lazzi (half-free), and unfree members of Saxon society and leading raids into the rich Frankish kingdom. Thus each of Charlemagne’s punitive expeditions, which began in 772 and lasted until 804, bit deeper into the heart of Saxony, leaving behind bitter memories of forced conversions, deportations, and massacres. These raids were inspired by religious as well as political zeal; with fire and sword, Charlemagne tried to break Saxon resistance both to Christianity and to Frankish dominance. Still, the decentralized nature of Saxon society made ultimate conquest extremely difficult. Whenever the Frankish army was occupied elsewhere, the Saxons could be counted on to revolt, to slaughter Frankish officials and priests, and to raid as far westward as they could. Charlemagne in turn would punish the offending tribes, as he did when he executed 4,500 Saxons at Verden, and garrison the defense points abandoned by the Saxons. In time, resistance to the Franks gave the Saxons a kind of unity under the leadership of Widukind, who succeeded longer than any other leader in holding together a majority of chieftains in armed resistance to the Franks. Ultimately, internal feuding led to the capitulation even of Widukind. He surrendered, was baptized, and, like Tassilo, was imprisoned in a monastery for the remainder of his life. Despite this victory, it would take another 20 years before Saxony would be finally subdued.
Charlemagne’s efforts were not limited to military repression, however. He also issued two edicts concerning the pacification and conversion of Saxony, which reveal the brutality of the process as well as its gradual success. The Capitulatio de Partibus Saxoniae (c. 785; “Capitulary for the Saxon Regions”) was intended to force the submission of the Saxons to the Franks and to Christianity, imposing the death penalty for destruction of churches, refusal of baptism, and violating the Lenten fast. The Capitulare Saxonicum (797; “Saxon Capitulary”), although not necessarily abrogating the earlier decree, replaced the harsher measures of the earlier capitulary with conversion through less brutal methods. Moreover, Frankish churchmen and aristocrats loyal to Charlemagne were introduced to secure and pacify the region. Although the northern regions that enjoyed Danish support remained outside of Frankish control, most of Saxony gradually moved into the united Frankish realm and would become a great centre of political, cultural, and religious life in the 10th century.
