Saint George's Day April 23.

St George is the patron saint of England and among the most famous of Christian figures. But of the man himself, nothing is certainly known. Our earliest source, Eusebius of Caesarea, writing c. 322, tells of a soldier of noble birth who was put to death under Diocletian at Nicomedia on 23 April, 303, but makes no mention of his name, his country or his place of burial. According to the apocryphal Acts of St George current in various versions in the Eastern Church from the fifth century, George held the rank of tribune in the Roman army and was beheaded by Diocletian for protesting against the Emperor's persecution of Christians. George rapidly became venerated throughout Christendom as an example of bravery in defence of the poor and the defenceless and of the Christian faith.
 

George was probably first made well known in England by Arculpus and Adamnan in the early eighth century. The Acts of St George, which recounted his visits to Caerleon and Glastonbury while on service in England, were translated into Anglo-Saxon. Among churches dedicated to St George was one at Doncaster in 1061. George was adopted as the patron saint of soldiers after he was said to have appeared to the Crusader army at the Battle of Antioch in 1098. Many similar stories were transmitted to the West by Crusaders who had heard them from Byzantine troops, and were circulated further by the troubadours. When Richard 1 was campaigning in Palestine in 1191-92 he put the army under the protection of St George.

Because of his widespread following, particularly in the Near East, and the many miracles attributed to him, George became universally recognized as a saint sometime after 900. Originally, veneration as a saint was authorized by local bishops but, after a number of scandals, the Popes began in the twelfth century to take control of the procedure and to systematize it. A lesser holiday in honour of St George, to be kept on 23 April, was declared by the Synod of Oxford in 1222; and St George had become acknowledged as Patron Saint of England by the end of the fourteenth century.
