By the end of the sixth century, the leaders of these communities were styling themselves kings, though it should not be assumed that all of them were Germanic in origin. The Bretwalda concept is taken as evidence of a number of early Anglo-Saxon elite families. What Bede seems to imply in his "Bretwalda" is the ability of leaders to extract tribute, overawe and/or protect the small regions, which may well have been relatively short-lived in any one instance. Ostensibly "Anglo-Saxon" dynasties variously replaced one another in this role in a discontinuous but influential and potent roll call of warrior elites. Importantly, whatever their origin or whenever they flourished, these dynasties established their claim to lordship through their links to extended kin, and possibly mythical, ties. As Helen Geake points out, "they all just happened to be related back to Woden".
