Saint Edmund the Martyr was a king of East Anglia who reigned in the 9th century. He is best known for his resistance against Viking invaders, particularly during the reign of King Sweyn Forkbeard. Edmund was captured and, according to legend, was tortured and ultimately killed for refusing to renounce his Christian faith. After his death, Saint Edmund became a symbol of bravery and martyrdom. His remains were buried at Bury St Edmunds, which later became a significant pilgrimage site. He was canonized by the Catholic Church, and his feast day is celebrated on November 20th.
