Boniface and The Carolingians
The support of the Frankish mayors of the palace (maior domos), and later the early Pippinid and Carolingian rulers, was essential for Boniface's work. Boniface had been under the protection of Charles Martel from 723 on. The Christian Frankish leaders desired to defeat their rival power, the non-Christian Saxons, and to incorporate the Saxon lands into their own growing empire. Boniface's destruction of indigenous Germanic pagan sites may have benefited the Franks in their campaign against the Saxons.
In 732, Boniface traveled again to Rome to report, and Pope Gregory II conferred upon him the pallium as archbishop with jurisdiction over Germany. Boniface again set out for what is now Germany, baptized thousands, and dealt with the problems of many other Christians who had fallen out of contact with the regular hierarchy of the Roman Catholic Church. During his third visit to Rome in 737–38, he was made papal legate for Germany.
After Boniface's third trip to Rome, Charles Martel erected four dioceses in Bavaria (Salzburg, Regensburg, Freising, and Passau) and gave them Boniface as archbishop and metropolitan over all Germany east of the Rhine. In 745, he was granted Mainz as metropolitan see. In 742, one of his disciples, Sturm (also known as Sturmi, or Sturmius), founded the abbey of Fulda not far from Boniface's earlier missionary outpost at Fritzlar. Although Sturm was the founding abbot of Fulda, Boniface was very involved in the foundation. The initial grant for the abbey was signed by Carloman, the son of Charles Martel, and a supporter of Boniface's reform efforts in the Frankish church. The saint himself explained to his old friend, Daniel of Winchester, that without the protection of Charles Martel he could “neither administer his church, defend his clergy, nor prevent idolatry.”
According to German historian Gunther Wolf, the high point of Boniface's career was the Concilium Germanicum, organized by Carloman in an unknown location in April 743. While Boniface was not able to safeguard the church from property seizures by the local nobility, he did achieve one goal, the adoption of stricter guidelines for the Frankish clergy, which often hailed directly from the nobility. After Carloman's resignation in 747 he maintained a sometimes turbulent relationship with the king of the Franks, Pepin; the claim that he would have crowned Pepin at Soissons in 751 is now generally discredited.
Boniface balanced this support and attempted to maintain some independence, however, by attaining the support of the papacy and of the Agilolfing rulers of Bavaria. In Frankish, Hessian, and Thuringian territory, he established the dioceses of Würzburg, and Erfurt. By appointing his own followers as bishops, he was able to retain some independence from the Carolingians, who most likely were content to give him leeway as long as Christianity was imposed on the Saxons and other Germanic tribes.
