 The return of East Anglia to pagan rule does not necessarily mean that there was an overt struggle between the worship of the Anglo-Saxon gods and the worship of Christ, but could express a reaction against Christianity amongst the East Angles, prompted by Edwin's rise to power and his subsequent dominance over their king.The ancestry of Ricberht is unknown and it is unclear as to whether he ever ruled after he killed Eorpwald, but in 630 or 631, three years after Eorpwald's assassination, Sigeberht returned from exile in Gaul and became king of the East Angles.At Sutton Hoo (near Woodbridge, in Suffolk) is the site of two 6th-7th century Anglo-Saxon cemeteries, where it is believed that members of Eorpwald's dynasty were entombed under large earth mounds.
