Eardwulf was King of Kent, jointly with Æðelberht II.
Eardwulf is known from two charters, one is undated [1], but identifies Eardwulf’s father as Eadberht I (a patre meo Eadberhtuo); the other has a date that is incompatible with its witness list [2]), as it is dated 762, but witnessed by Archbishop Cuðbert, who died in 760; it was also witnessed by King Æðelberht II (Aethilberchtus rex Cantie).
