Guthrum II

[2] Until the death of Guthrum, the coins of East Anglia provide an essential guide to the rulers of the kingdom.

After the killing of King Æthelberht II of East Anglia in 794, only two kings—Edmund, better known as Saint Edmund the Martyr, and Guthrum—are named in near-contemporary written records, while all others are known only from the numismatic evidence provided by surviving coins.

[5] In his translation of the German historian Johann Martin Lappenberg's History of England under the Anglo-Saxon Kings, Benjamin Thorpe refers to King Guthrum II as having led the East Anglians in 906 when peace was made with Edward the Elder.

According to Stevenson's translation, Wallingford wrote that the King Guthrum who had made peace with Alfred and whose death in 890 is not disputed, had left England for Denmark and returned again during the reign of Edward at the request of his son Æthelstan.

Frederick Attenborough's Laws of the Earliest English Kings (1921) discussed them and referred to the work of German historian Felix Liebermann.
