Boniface, OSB (Latin: Bonifatius; c. 675 – 5 June 754) was an English Benedictine monk and leading figure in the Anglo-Saxon mission to the Germanic parts of the Frankish Empire during the eighth century. He organised significant foundations of the church in Germany and was made archbishop of Mainz by Pope Gregory III. He was martyred in Frisia in 754, along with 52 others, and his remains were returned to Fulda, where they rest in a sarcophagus which has become a site of pilgrimage.
