East Anglia was first ruled by semi-historical kings from the Wuffings dynasty, who, according to the 9th-century "Historia Brittonum" of Nennius, descended to Wuffa of East Anglia from Wōden. In the "Anglo-Saxon Chronicle", the most important historical source for the Anglo-Saxon period, only Rædwald of East Anglia and his successors Eorpwald, Anna, Æthelberht and Edmund the Martyr are mentioned. An important source of information is Bede's "Historia ecclesiastica gentis Anglorum", which describes events during the reigns of several East Anglian kings, including Raedwald, the first king who is known by more than a name.
