While exiled from East Anglia to France during the reign of King Redwald, Sigeberht converted to Christianity. He returned to East Anglia as king in 630, the first Christian king of the region. Worked with Archbishop Honorius of Canterbury and Saint Fursey to bring Christianity to his subjects. Helped found churches, schools and monasteries. After a short reign, he abdicated in favour of Ecgric and retired to become a monk. When Mercia invaded East Anglia, Sigeberht was taken against his will from his monastery to the battle field in hopes that he would rally the army; he refused to carry a weapon or fight, and was killed by the pagan King Penda of Mercia. Venerated in East Anglia as a martyr.
