Note 117 — BOOK I. (continued 3)
John Sharpe translation
The kingdom of Sussex was founded by Ælla, who arrived in Britain with three vessels, and accompanied by his three sons, A.D. 477. He seems to have attained a very high degree of power, and was succeeded by his son Cissa.—The affairs of this kingdom are extremely obscure; it appears to have been sometimes dependent on Kent and sometimes on Wessex until finally united to the latter by Egbert, A.D. 823.
