Kingdom of East Anglia [SEP] Geography
The kingdom of the East Angles bordered the North Sea to the north and the east, with the River Stour historically dividing it from the East Saxons to the south. The North Sea provided a "thriving maritime link to Scandinavia and the northern reaches of Germany", according to the historian Richard Hoggett. The kingdom's western boundary varied from the rivers Ouse, Lark and Kennett to further westwards, as far as the Cam in what is now Cambridgeshire. At its greatest extent, the kingdom comprised the modern-day counties of Norfolk, Suffolk and parts of eastern Cambridgeshire. Erosion on the eastern border and deposition on the north coast altered the East Anglian coastline in Roman and Anglo-Saxon times (and continues to do so).
