This article investigates the events of Rudolf II's military campaign in Italy (922) and considers the political ramification of this, both immediately thereafter and subsequently during the rule of Rudolf. Particular attention is paid to the career of Boniface of the Hucpoldings: an Italian aristocrat who attained prominence thanks to his close relationship with Rudolf. The Hucpoldings belonged to the aristocratic elite of the Carolingian empire, came to Italy under Lothar I (c.847) and tried to settle there. Until now, scholars have underestimated their role in the wider context of the early medieval Italian kingdom. This study will stress how Boniface's career was a turning point in the lineage's development, and how his political achievements were essential for his kinship's further hegemony.
