Conversio Bagoariorum et Carantanorum is an anonymous ninth-century Latin text concerning the Christianization of the Bavarian and Carantanian peoples and the missionary activity in the eastern Frankish frontier, linking ecclesiastical narratives to the political fortunes of the Carolingians, the Babenberg family, and the Salzburg see. The work functions as both a hagiographical chronicle and an ecclesiastical petition, addressing disputes over episcopal jurisdiction, monastic foundations, and relations among Nicholas I, Louis II of Bavaria?, and later rulers in the context of Moravian and Avar legacies.

Background and Historical Context

The narrative situates itself amid the conversion campaigns associated with Saint Rupert, Boniface, and later missionaries who operated across the Danube corridor, the Alps and the Pannonia. It unfolds against geopolitical tensions among the East Francia rulers, the Kingdom of Italy contests, and the territorial ambitions of the Great Moravia and the Avars. The text reflects ecclesiastical disputes involving the Aquileia and the Salzburg over missionary rights, and it implicates actors such as Carloman, Charles the Bald, and Arnulf in the shifting frontier politics.

Authorship and Date

Scholars have debated attribution, suggesting authorship by clerics linked to the Salzburg chancery or monastic centers like Lorsch and St. Emmeram. The composition is usually dated to the late ninth century, with proposed years ranging around the 870s–880s, contemporaneous with pontificates such as Hadrian II and reigns of Louis the German and Charles the Fat. Manuscript evidence and internal allusions have invited comparisons with texts of the Carolingian Renaissance and with works by Einhard and Hincmar.

Content and Structure

The work combines hagiography, annalistic notices, and juridical argumentation, organizing episodes about episcopal foundations, missionary labors, miracles attributed to figures like Emmeram and Rupert, and narratives of baptisms among Bavarians and Carantanians. It opens with apostolic and missionary genealogies referencing Pope Gregory I's legacy and continues with accounts of regional rulers including Odilo, Agilolfing ties, and the influence of families such as Babenberg. The text's juridical sections assert metropolitan claims reminiscent of disputes adjudicated at synods like the Synod of Worms and contested at councils associated with Nicholas I.

Historical Accuracy and Sources

Historians assess the Conversio against contemporaneous chronicles such as the Annals of Fulda, the Annals of St-Bertin, and the Chronicle of Moissac, noting both corroborations and hagiographical embellishments. The work draws on oral traditions about missions of Boniface and the activities of Vergilius (Virgil) and makes claims about territorial ecclesiastical rights that appear motivated by later Salzburg interests confronting Aquileia and Mainz. Archaeological finds in Regensburg, Salzburg city, and sites in Carinthia have been used to test the Conversio's topographical and institutional claims, with mixed conclusions about chronology and causal attributions.

Influence and Reception

The Conversio influenced medieval perceptions of missionary origins in the eastern Carolingian frontier and was cited or echoed in later medieval cartularies, episcopal records, and historiographical works tied to Salzburg and Bavarian identity, including texts produced under Adalwin and Arn (?). Renaissance and early modern scholars such as Meier von Eck and Enlightenment antiquaries engaged with its claims during debates over ecclesiastical precedence involving Imperial Diet patrons, while modern historians including Ferdinand Lot and Dieter Geuenich have re-evaluated its utility for reconstructing missionary networks and diplomatic exchanges involving Nicholas I and Louis the German.

Manuscripts and Transmission

Surviving witnesses of the text are preserved in a small number of medieval codices associated with cathedral libraries and monastic scriptoria such as those of Salzburg Cathedral, Bamberg collections, and compilations linked to Regensburg and Lorsch. Scribal transmission exhibits variants that reflect editorial interventions by clerics connected to Salzburg and by compilers participating in the monastic reform networks of the ninth and tenth centuries. Modern editions rely on collation of manuscripts and comparisons with the Monumenta Germaniae Historica corpus and critical apparatuses developed by medievalists in the Austrian Academy of Sciences and the Monumenta Scholia projects.
