What we do know is that Saint George was born to an upper-class Christian family, before he become a Roman soldier. When his father died, he and his mother returned to Palestine, and he decided to join the retinue of Diocletian, the Roman Emperor at the time.
He earned his reputation as a protector of Christianity after he refused orders from Diocletian to persecute followers of the religion at the start of the 4th century. He then resigned.
And despite being cruelly tortured at the order of the emperor, Saint George refused to denounce his faith. His actions saw him dragged through the streets of Diospolis (now Lydda) in Palestine and beheaded.
