Sæberht of Essex
Sæberht, Saberht or Sæbert (d. 616) was an Anglo-Saxon King of Essex (r. 604 – 616), in succession of his father King Sledd. He is known as the first East Saxon king to have been converted to Christianity. The principal source for his reign is the early 8th-century "Historia Ecclesiastica gentis Anglorum" by Bede (d. 735), who claims to have derived his information about the missionary work of Mellitus among the East Saxons from Abbot Albinus of Canterbury through the London priest Nothhelm, later Archbishop of Canterbury (d. 739). Other sources include the "Anglo-Saxon Chronicle
