Saint Boniface ( 675? – 5 June 754 AD), born Winfrid, Wynfrith, or Wynfryth in the kingdom of Wessex in Anglo-Saxon England, was a leading figure in the Anglo-Saxon mission to the Germanic parts of the Frankish Empire during the 8th century. He established the first organized Christianity in many parts of Germania. He is the patron saint of Germania, the first archbishop of Mainz and the "Apostle of the Germans". He was killed in Frisia in 754, along with 52 others. His remains were returned to Fulda, where they rest in a sarcophagus which became a site of pilgrimage. Facts about Boniface's life and death as well as his work became widely known, since there is a wealth of material available—a number of vitae, especially the near-contemporary Vita Bonifatii auctore Willibaldi, and legal documents, possibly some sermons, and above all his correspondence.
