Dagobert II was a Merovingian king who ruled for about four years in Austrasia, the Frankish kingdom which included northeastern France, Belgium and the Rhineland. His reign probably began in late 675 or early 676. This chapter first reviews what we know of Dagobert and next examines the Vita Dagoberti. It then looks at how Dagobert II was rediscovered via the Life of Wilfrid in the seventeenth century, and was subsequently re-inscribed in the history of the period. This leads readers to an evaluation of the Life of Wilfred as a source, reflections on the significance of Wilfrid himself, and further thoughts on the relationship between memory and tradition. The Life of Wilfrid is therefore a text that is to readers vital for historical research, but not one of which more than a handful of early medieval people were aware.
