Anglo-Saxon Britain. By

Anglo-Saxon England was early medieval England, existing from the 5th to the 11th century from the end of Roman Britain until the Norman conquest in 1066. It consisted of various Anglo-Saxon kingdoms until 927 when it was united as the Kingdom of England by King Æthelstan (r. 927-939). It became part of the North Sea Empire of Cnut the Great, a personal union between England, Denmark and Norway in the 11th century. The Anglo-Saxons were the members of Germanic-speaking groups who migrated to the southern half of the island from continental Europe, and their cultural descendants. Anglo-Saxon history thus begins during the period of Sub-Roman Britain following the end of Roman control, and traces the establishment of Anglo-Saxon kingdoms in the 5th and 6th centuries
