ANGLO-SAXON BRITAIN - see category: Anglo-Saxon Britain
From about 500 AD, a new wave of tribes from northern Europe began moving into Britain; the Angles invading Norfolk, Yorkshire and Northumbrian coasts; the Jutes and Saxons invading further south, through the Thames estuary and along the Kent, Sussex and Wessex shores. These new peoples eventually formed the seven kingdoms of the Heptarchy of Anglo-Saxon England; Wessex, Sussex, Kent, Essex, East Anglia, Mercia and Northumbria (Deira and Bernicia).
Essex, the kingdom of the East Saxons, included the Roman towns of London and Colchester. The kingdom of Essex was absorbed into the kingdom of Wessex.
The kingdom of Mercia was the dominant kingdom in the Heptarchy of Anglo-Saxon England. A series of battles with the invading Vikings of 'The Great Heathen Army' deposed the King of Mercia, a settlement was reached between the Danes and Wessex resulting in the retreat of the Viking army to Northumbria. - page : Mercia- category : Kingdom of Mercia - see page: The Viking Great Army aka The Great Heathen Army
