The Fourth Age of Britain
Anglo-Saxon England refers to the period of the history of England that lasts from the end of Roman Britain and the establishment of Anglo-Saxon kingdoms in the 5th century until the Norman conquest of England in 1066. Anglo-Saxon is a general term that refers to the Germanic settlers who came to Britain during the 5th and 6th centuries, including Angles, Saxons, Frisians and Jutes.
Anglo-Saxon England until the 9th century was dominated by the Heptarchy, the kingdoms of Northumbria, Mercia, East Anglia, Essex, Kent, Sussex and Wessex. These kingdoms were pagan during the early period, but were Christianized during the 7th century. Paganism had a final stronghold in a period of Mercian hegemony during the 640s, ending with the death of King Penda in 655.
Facing the threat of Viking invasions, the House of Wessex became dominant during the 9th century, under the rule of Alfred the Great. During the 10th century, the individual kingdoms unified under the rule of Wessex into the Kingdom of England, which stood opposed to the Danelaw, the Viking kingdoms established from the 9th century in the North of England and the East Midlands. The Kingdom of England fell in the Viking invasion from Denmark in 1013, and was ruled by the House of Denmark until 1042, when the Anglo-Saxon House of Wessex was restored. The last Anglo-Saxon king, Harold Godwinson, fell at the Battle of Hastings in 1066.
