Oswine of Deira

Oswine of Deira was a king in northern England, ruling Deira in Northumbria, and in 642 succeeded Saint Oswald as ruler of that land. He reigned only nine years and was known for his humility and mercy. He was unjustly killed at Gilling in Yorkshire by order of his cousin Oswy on 20 August 651, and has ever since been venerated as a martyr. He is a saint of the undivided Church, venerated in the West.

His commemoration falls on 20 August (new calendar); the Churches on the Old Calendar keep the same day of the Menaion on 2 September of the civil calendar.
