The Wuffingas, Uffingas or Wiffings were the ruling dynasty of East Anglia, the long-lived Anglo-Saxon kingdom which today includes the English counties of Norfolk and Suffolk. The Wuffingas took their name from Wuffa, an early East Anglian king. Nothing is known of the members of the dynasty before Rædwald, who ruled from about 599 to 624. The Viking invasions of the 9th century and Dissolution of the monasteries in the 16th century both led to the destruction of documents relating to the rule of the Wuffingas. The last of the Wuffingas kings was Ælfwald, who died in 749; he was succeeded by kings whose lineage is unknown. The kingdom of East Anglia was invaded by peoples from northern Europe during the 5th and 6th centuries. Historical sources relating to the genealogy of the East Anglian kings include the Anglo-Saxon Chronicle and the 8th century English monk Bede's Ecclesiastical History, both compiled many years after the kingdom was formed, as well as a pedigree of Ælfwald contained in the Anglian collection that dates from the 9th century. In the pedigree, Ælfwald is claimed to descend from the god Wōden. The earliest kings of East Anglia were known as the Wuffingas, named after the semi-historical founder of the dynasty, Wuffa. Rædwald (died 625) is the first of the country's kings known to have ruled. Bede identified Rædwald's father as Tytil and his grandfather as Wuffa; their respective accession dates of 571 and 578 were given by the 13th century English chronicler Roger of Wendover. The Historia Brittonum lists Wehha, father of Wuffa. as the first of the Wuffingas, which perhaps sets the date for the origins of the dynasty to the middle of the 6th century. Wuffa is thought to mean "little wolf", suggesting that the dynastic name Wuffingas translates as "kin of the wolf", making it etymologically the same as the Wulfings clan named in Beowulf and the Old English poem "Widsith". After 749, East Anglia was ruled either by the rulers of Mercia, or by kings whose genealogy is not known.
