Rædwald (, 'power in counsel'), also rendered as Raedwald or Redwald, was a 7th-century king of East Anglia, a long-lived Anglo-Saxon kingdom which today includes the English counties of Norfolk and Suffolk. He was the son of Tytila of East Anglia and a member of the Wuffingas dynasty (named after his grandfather, Wuffa), who were the first kings of the East Angles. Details about Rædwald's reign are scarce, primarily because the Viking invasions of the 9th century destroyed the monasteries in East Anglia where many documents would have been kept. Rædwald reigned from about 599 until his death around 624, initially under the overlordship of Æthelberht of Kent. In 616, as a result of fighting the Battle of the River Idle and defeating Æthelfrith of Northumbria, he was able to install Edwin, who was acquiescent to his authority, as the new king of Northumbria. During the battle, both Æthelfrith and Rædwald's son Rægenhere were killed.
