From poachers to gamekeepers: Scandinavian warlords and Carolingian kings

This article represents the first comprehensive study of the commendation and conversion of Viking leaders by Carolingian rulers, from the first recorded instance under Charlemagne to the agreement with Rollo in the early tenth century. The survey underlines how widespread the practice was, and permits an assessment of its effectiveness as a defensive strategy against Scandinavian incursions. The outcome varied: some Scandinavians found themselves defending Frankish territory against Viking attack, others acted as intermediaries between Franks and Scandinavians, still others were granted Frankish benefices but never trusted, and ultimately killed. Nonetheless, the article demonstrates that in the majority of cases the practice of commendation and conversion worked to the Carolingians’ advantage, neutralizing potential enemies or even turning them into useful allies.
