St Edmund was a king of East Anglia who is venerated as a martyr and saint in Christianity. He is believed to have reigned in the 9th century and is known for his resistance against Viking invasions. According to legend, he was captured by the Vikings and, rather than renounce his faith, he was executed, becoming a symbol of bravery and devotion. His feast day is celebrated on November 20th, and he is the patron saint of England and Tavistock. St Edmund's shrine in Bury St Edmunds became a significant pilgrimage site during the Middle Ages, attracting many visitors seeking healing and blessings.
