 Berkshire appears to have passed from Mercian to West Saxon control during Beorhtwulf's reign. The Welsh are recorded to have rebelled against Beorhtwulf's successor, Burgred, shortly after Beorhtwulf's death, suggesting that Beorhtwulf had been their overlord. Charters from Beorthwulf's reign show a strained relationship with the church, as Beorhtwulf seized land and subsequently returned it.
