Following the withdrawal of the Romans from southern Britain after 410, Germanic tribes such as the Angles and Saxons began to settle in the southeastern part of the island. East Anglia is regarded by many scholars as a region in which this settlement was particularly early and dense; the area's name derives from that of the Angles. Over time, the remnants of the pre-existing Brittonic population adopted the culture of the newcomers.Toby F.
