DiumaNOTOC Diuma (or Dwyna or Duma) was the first Bishop of Mercia in the Anglo-Saxon Kingdom of Mercia, during the Early Middle Ages. All that is known of Diuma's life is contained in a short account in Bede's Ecclesiastical History of the English People. Diuma was an Irishman, and was one of four priests, Cedd, Atta, Betti and Diuma, from the Kingdom of Northumbria, who accompanied the newly baptised Peada, son of Penda (King of Mercia) back to Mercia in 653. Peada became a Christian when he married Alhflaed, daughter of Oswiu, King of Northumbria.
Peada of MerciaPeada (died 656), a son of Penda, was briefly King of southern Mercia after his father's death in November 655 and until his own death in the spring of the next year. Around the year 653 Peada was made king of the Middle Angles by his father, Penda. Bede, describing Peada as "an excellent youth, and most worthy of the title and person of a king", wrote that he sought to marry Alchflaed of Bernicia, the daughter of King Oswiu of Northumbria; Oswiu, however, made this conditional upon Peada's baptism and conversion to Christianity, along with the Middle Angles (Peada was, at this time, still a pagan, like his father).
OswiuOswiu, also known as Oswy or Oswig (Ōswīg; c. 612 – 15 February 670), was King of Bernicia from 642 and of Northumbria from 654 until his death. He is notable for his role at the Synod of Whitby in 664, which ultimately brought the church in Northumbria into conformity with the wider Catholic Church. One of the sons of Æthelfrith of Bernicia, Oswiu became king following the death of his brother Oswald in 642. Unlike Oswald, Oswiu struggled to exert authority over Deira, the other constituent kingdom of medieval Northumbria, for much of his reign.
