St Peter's Abbey (German: Stift Sankt Peter), or St Peter's Archabbey (German: Erzabtei Stift Sankt Peter, Latin: Archiabbatia sancti Petri Salisburgensis), is a Benedictine monastery and former cathedral in the Austrian city of Salzburg. It is considered one of the oldest monasteries in the German-speaking area, and in fact the oldest with a continuous history since its foundation in 696.
Theodo or Theoto (about 625 – 11 December c. 716), sometimes numbered Theodo II, was the Duke of Bavaria from 670 or, more probably, 680 to his death. It is with Theodo that the well-sourced history of Bavaria begins. He strengthened his duchy internally and externally and, according to the medieval chronicler Arbeo of Freising, he was a prince of great power whose fame extended beyond his borders.
