St. George was a soldier of the Roman army who was tortured and beheaded for his Christian faith in the year 303, in Lydda (in modern day Palestine). He was likely born in Cappadocia, of a Cappadocian father and a Palestinian mother of noble rank. At the death of his father (possibly martyrdom) he moved to Palestine with his mother where he joined the military and apparently served with some distinction, meriting several promotions in rank.
One account of the martyrdom of St. George is Eusebius´ Ecclesiastical History, which relates that when the emperor Diocletian issued an edict "to tear down the churches to the foundations and to destroy the Sacred Scriptures by fire…a certain man, of no mean origin, but highly esteemed for his temporal dignities, stimulated by a divine zeal, and excited by an ardent faith, took it as it was openly placed and posted up for public inspection, and tore it to shreds as a most profane and wicked act." This act of instransigence and holy audacity enraged the emperor who had the man tortured and killed. This man “of no mean origin”, i.e. of nobility, has been identified by more than one ancient source, including Eusebius, as St. George, though most modern historians of the period state that this is unlikely.
St. George is usually depicted in Christian art as a soldier on horseback killing a dragon with a lance. This image is a representation of a popular legend of St. George which first appears in 1265 in a romance titled "The Golden Legend," in which he saved a town terrorized by a dragon with one blow of his lance. The image, however, is also, and more significantly, a powerful symbol of the victory of Christian faith over evil (sometimes interpreted more contextually in the early Church as “paganism”), personified by the devil who is symbolized by the dragon according to the imagery in Revelations.
St. George is invoked as a patron of military causes, not only because he was a soldier, but also, and primarily, due to his appearance to the Christian armies before the battle of Antioch, in which they were victorious, and to King Richard the Lionheart of England during his crusade against the Saracens.
The cult of St.George, while universal, remains strongest in the Eastern Church where he is venerated as “The Great Martyr.” Accounts of early pilgrims identify the seat of the cult of St.George at his burial site in Lydda. The cult has been in existence since the 4th century, soon after his death.
St. George is the patron of soldiers and the patron of many nations, including Palestine; Lebanon; England; Georgia; Malta. He is also the patron of Palestinian Christians and of Boy Scouts. He is invoked by sufferers of herpes, skin diseases, skin rashes, syphilis, and snakebites.
