Old English (Anglo-Saxon) developed from the dialects brought to Britain by Germanic tribes — the Angles, Saxons, and Jutes — who began settling in Britain from the 5th century AD, following the withdrawal of the Romans. The Celts were the pre-existing inhabitants, not speakers of English. The Angles gave England its name (Englaland = land of the Angles). Old English lasted roughly from 450–1150 AD.
