Historians have generally accepted Bede's report of Coenred's and Offa's abdications, but Barbara Yorke has suggested that they may not have relinquished their thrones voluntarily. There are instances of kings being forcibly removed and placed in holy orders to make them ineligible for kingship; one such was King Osred II of Northumbria, who was forced into a monastery. On the other hand, if Coenred went willingly, as Bede relates, then the apparently friendly relationship between Offa and Coenred, his overlord, makes it clear that the relationship between an overlord and his underking was not hostile in every case.
