Oswald of Northumbria
King of Northumbria
Feast: 5 August (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Oswald, son of King Ethelfrid, fled in youth to the Scots and was cared for at St Columba's monastery on Iona. In 635 he returned and, encouraged by a vision, won the battle of Heavenfield and became King of Northumbria.
Thoroughly grounded in the faith, he was called by Bede 'the most powerful and most Christian King'. He was killed fighting the pagan Penda of Mercia at Maserfield on 5 August 642, his last words a prayer for his soldiers' souls.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
A Christian king who died praying for his men.
