The East Anglian flag as it is known today was invented by George Henry Langham and adopted by the London Society of East Anglians. It was first mentioned in print in 1900 and was flown locally in various places in Norfolk, but has no official status. It draws upon the coat of arms of the Wuffingas dynasty: three crowns in a blue shield, the colour of the Swedish flag, superimposed on a St. George's cross. The device refers to an old legend of the three crowns of East Anglia, and the blue colour represents the Anglo-Scandinavian heritage of much of East Anglia.
The three crowns of East Anglia appear, carved in stone, on the baptismal font (c.1400) in the parish church of Saxmundham, in Suffolk.

The crowns also appear in the arms of the borough of Bury St. Edmunds and the University of East Anglia.
