What do we know about St George?
Saint George [d. 23 April 303] was a soldier of Cappadocian Greek origins, member of the Praetorian Guard for Roman emperor Diocletian who was sentenced to death for refusing to recant his Christian faith.
Several nations claim St George:-
Aragon in Spain
George was born to Greek Christian parents, in Cappadocia. His father died for the faith when George was fourteen, and his mother returned with George to her homeland of Syria. A few years later, George's mother died. George travels to the capital Nicomedia and joins the Roman army. George is persecuted by one Dadianus.
Why did England adopt St George?
The establishment of George as a popular and protective saint in the West that had captured the medieval imagination was codified by the official elevation of his feast to a festum duplex at a church council in 1416, on the date that had become associated with his martyrdom, 23 April. When the English Reformation severely curtailed the saints' days in the calendar, Saint George's Day was among the holidays that continued to be observed.
