The Anglo-Saxons, in some contexts simply called Saxons or the English, were a cultural group who spoke Old English and inhabited much of what is now England and south-eastern Scotland in the Early Middle Ages. They traced their origins to Germanic settlers who became one of the most important cultural groups in Britain by the 5th century. The Anglo-Saxon period in Britain is considered to have started by about 450 and ended in 1066, with the Norman Conquest. Although the details of their early settlement and political development are not clear, by the 8th century an Anglo-Saxon cultural identity which was generally called Englisc had developed out of the interaction of these settlers with the existing Romano-British culture. By 1066, most of the people of what is now England spoke Old English, and were considered English. Viking and Norman invasions changed the politics and culture of England significantly, but the overarching Anglo-Saxon identity evolved and remained dominant even after these major changes.
