Peter (bishop of Passau)

[2][3] Petrus, from 1257 to 1264, exercised the office of a canon in Breslau, and at the same time served as the courtmaster of the Duke Vladislav of Silesia.

Finally, on 24 November, Pope Clement IV, who had reserved the seat of both bishoprics, appointed Peter as Bishop of Passau.

In 1267 Peter mediated the conflict between King Ottokar of Bohemia, who occupied the city of Passau in 1266, and Henry, the Duke of Lower Bavaria.

In 1274 he called for a diocesan synod to Passau, and in October he took part in a provincial synod in Salzburg, which confirmed and extended the resolutions of Vienna.

In the same year, he moved from Ottokar to the side of King Rudolf of Habsburg, which resulted in extensive privilege confirmations, including the preservation of the Innnoll at Obernberg.
