Old English developed from a set of West Germanic dialects, often grouped as Anglo-Frisian or North Sea Germanic, and originally spoken along the coasts of Frisia, Lower Saxony and southern Jutland by Germanic peoples known to the historical record as the Angles, Saxons, and Jutes.[30] From the 5th century, the Anglo-Saxons settled Britain as the Roman economy and administration collapsed. By the 7th century, this Germanic language of the Anglo-Saxons became dominant in Britain, replacing the languages of Roman Britain (43–409): Common Brittonic, a Celtic language, and British Latin, brought to Britain by the Roman occupation.[31][32][33] At this time, these dialects generally resisted influence from the then-local Brittonic and Latin languages. England and English (originally Ænglaland and Ænglisc) are both named after the Angles.[34]
