I did a lot of my growing up in East Anglia. The long horizons and big cold skies of the east of England formed the backdrop to my years at agricultural college, and there is still something of a sense of homecoming when I find myself driving through the expansive, gently undulating cornfields of Cambridgeshire, the peaceful back roads of rural Essex or the medieval wool towns of Suffolk.The Anglo-Saxon kingdom of East Anglia, established in the sixth century, originally consisted of what are today the counties of Norfolk and Suffolk, although Essex and Cambridgeshire are included in most modern definitions of the region. The area saw dense settlement by continental Germanic speaking tribes from the early fifth century on, after Roman rule in Britain had collapsed. Studies have shown that modern East Anglians owe far more of their genetic make-up to those Germanic tribes than to the Romano-British peoples who preceded them.
