Anglo-Saxon is the term usually use to describe the peoples living in the south and east of Great Britain from the early 5th century AD to the Norman conquest of 1066. Benedictine monk Bede identified them as the descendants of three Germanic tribes: the Angles, Jutes and the Saxons, who originated from the Jutland peninsula and Niedersachsen (Lower Saxony). The Angles may have come from Angeln, and Bede wrote their nation came to Britain, leaving their land empty. They spoke closely related Germanic dialects. The Anglo-Saxons knew themselves as the "Englisc," from which the word "English" derives.
