East Saxon in the context of "Early Medieval period"

The Kingdom of the Kentish, today referred to as the Kingdom of Kent, was an early medieval kingdom in what is now South East England. It existed from either the fifth or the sixth century AD until it was fully absorbed into the Kingdom of Wessex in the mid-9th century and later into the Kingdom of England in the early 10th century.

Under the preceding Romano-British administration the area of Kent faced repeated attacks from seafaring raiders during the fourth century AD. It is likely that Germanic-speaking foederati were invited to settle in the area as mercenaries. Following the end of Roman administration in 410, further linguistically Germanic tribal groups moved into the area, as testified by both archaeological evidence and Late Anglo-Saxon textual sources. The primary ethnic group to settle in the area appears to have been the Jutes: they established their Kingdom in East Kent and may initially have been under the dominion of the Kingdom of Francia. It has been argued that an East Saxon or Middle Saxon community initially settled in West Kent and merged with the expanding kingdom of East Kent in the sixth century, but this is uncertain.
