"Conrad of Babenberg (c. 1115 – 28 September 1168) was a nobleman and prelate of the Holy Roman Empire. He was the bishop of Passau (as Conrad I) from 1148/1149 until 1164 and then archbishop of Salzburg (as Conrad II) until his death, although he lost control of Salzburg when he was placed under the imperial ban in 1166.
Conrad came from the House of Babenberg. His father, Leopold III, was the Margrave of Austria, while his mother, Agnes of Waiblingen, was the daughter of the Emperor Henry IV. Prior to her marriage to Leopold, Agnes was married to Frederick I, Duke of Swabia, of the House of Hohenstaufen. Through Frederick, she was the mother of one king of Germany and grandmother of another: Cornad III (1138–52) and Frederick I (1152–90), Conrad of Babenberg's half-brother and nephew, respectively. One of Conrad's full brothers, Otto, became the famous bishop of Freising." - (en.wikipedia.org 16.01.2022)
