How was Bavaria converted to Christianity during the 7th and 8th centuries?

The Christianization of Bavaria during the 7th and 8th centuries was a gradual process driven by the support of local dukes, the efforts of wandering missionaries, and the systematic organizational work of the church.

Initially, Christianity survived only in isolated pockets among remnants of the Roman population. By the late 7th century, missionaries from the west began active evangelization with the backing of Bavarian dukes. A significant milestone occurred at the end of the 7th century when St. Rupert, arriving from the Rhine, founded the church of Salzburg.12

In the 8th century, the process became more structured under St. Boniface. Commissioned by Pope Gregory III to organize the church in Bavaria, Boniface established four initial bishoprics, later adding a fifth. His efforts replaced the earlier, more haphazard methods of Irish missionaries with a unified ecclesiastical structure under the authority of Rome. This institutionalization not only solidified the faith but also facilitated Bavaria's eventual political incorporation into the Carolingian empire.34
