Sutton Hoo is the supposed burial site of Rædwald, a king from which English period?

The Anglo-Saxons were a cultural group who inhabited Great Britain from the 5th century. They comprise people from Germanic tribes who migrated to the island from continental Europe, their descendants, and indigenous British groups who adopted many aspects of Anglo-Saxon culture and language; the cultural foundations laid by the Anglo-Saxons are the foundation of the modern English legal system and of many aspects of English society; the modern English language owes over half its words – including the most common words of everyday speech – to the language of the Anglo-Saxons. Historically, the Anglo-Saxon period denotes the period in Britain between about 450 and 1066.

From around 616, Rædwald was the most powerful of the English kings south of the River Humber. He was referred to in the Anglo-Saxon Chronicle, written centuries after his death, as a bretwalda (an Old English term meaning 'Britain-ruler' or 'wide-ruler').

He was the first king of the East Angles to become a Christian, converting at Æthelberht's court some time before 605, whilst at the same time maintaining a pagan temple. In receiving the faith he helped to ensure the survival of Christianity in East Anglia during the apostasy of the Anglo-Saxon kingdoms of Essex and Kent. He is generally considered by historians to be the most favoured candidate for the occupant of the Sutton Hoo ship-burial, although other theories have been advanced.
