(Saint) King, Martyr (January 25) (7th century) The First Christian King of East Anglia. Seconded by Saint Felix, who founded the See of Dunwich, and by Saint Fursey, he induced his subjects to embrace Christianity. He had retired into a monastery; but, when the fierce Penda of Mercia threatened the East Anglians with Axe and sword, his people recalled Sigebert. He fell in battle (A.D. 635) and, as he was fighting against Pagans, acquired the title and honours of a Martyr.
