Suffolk, it must be remembered, is not, like Cambridgeshire, Bedfordshire, and other counties named after their chief town, an artificial division of the land, called into being by the Government merely as an administrative unit, but, like the Isle of Ely, one of the originally independent principalities the gradual accretion of which has formed England. Very early Suffolk and Norfolk joined together in one East Anglian Kingdom; but that Kingdom endured for centuries, and was not extinguished till its last monarch, St. Edmund, was murdered by the Danes in their great raid of 870 A.D. He was, indeed, but a tributary monarch, under the King of the English; but this was then only a quite recent arrangement, and his predecessors had been wholly independent sovereigns. For many years they were engaged in a heroic struggle to preserve their independence against Mercia, the great power which occupied all the Midlands, and therefore it was that they fixed their Royal abode at Exning, close to the great dyke which bulwarked the East Anglian realm, as, long before, it had bulwarked the Icenian. Hence it came about that Exning was the birthplace of St. Etheldreda, the foundress of our great "sacred fane" at Ely, round which, almost more than Cambridge itself, the fortunes of Cambridgeshire have centred. Her father, King Anna, was called to the East Anglian throne in troublous times. Christianity and Paganism were at death-grips throughout the land. And the latter cause was championed by the monarch who was, for the moment, far the most powerful of the English sovereigns, Penda, King of Mercia. From his central position he struck out north, south, and east, at his Christian neighbours. His first blows were against Northumbria, where he successively shattered the Roman Mission of Paulinus and the Celtic Mission of Aidan. Next he drove into exile Kenwalk, the first Christian King of Wessex, and finally, in 654, burst over the East Anglian frontier "like a wolf, so that Anna and his folk were devoured as in a moment."
