East Anglia

This is a history book. East Anglia is a region of the United Kingdom of Great Britain and Northern Ireland at the level of NUTS 2 for statistical purposes. It is one of three constituent parts of the East of England – a first level region. The name has also been applied to the ancient Anglo-Saxon kingdom of the East Angles. The region's name is derived from the Angles – a tribe that originated in Angeln, northern Germany. The region comprises four areas of local government: the administrative counties of Norfolk, Suffolk and Cambridgeshire and the unitary authority area of the city of Peterborough. East Anglia initially consisted of Norfolk and Suffolk, but upon the marriage of the East Anglian princess Etheldreda, the Isle of Ely also became part of the kingdom. The Kingdom of the East Angles, formed about the year 520 by the merging of the North and the South Folk (Angles who had settled in the former lands of the Iceni during the previous century), was one of the seven Anglo-Saxon heptarchy kingdoms (as defined in the 12th century writings of Henry of Huntingdon). For a brief period following a victory over the rival kingdom of Northumbria around the year 616, East Anglia was the most powerful of the Anglo-Saxon kingdoms of England, and its King Raedwald was Bretwalda (overlord of the Anglo-Saxons kingdoms). But this did not last: over the next forty years, East Anglia was defeated by the Mercians twice, and it continued to weaken relative to the other kingdoms until in 794, Offa of Mercia had its king Æthelberht killed and took control of the kingdom himself.
