Primary: Offa 7(King of the Mercians, 757-796): Offa 7 organized things well in his kingdom but acted avariciously and cruelly.
(Other): Alcuin 1(Author, deacon and abbot of Tours, c.735-804): Alcuin 1 counselled Cenwulf 3 to carry out diligently those things which Offa 7 did well in his kingdom; if he acted avariciously or cruelly, Cenwulf 3 should wholly avoid this.
