Adalbert III of Bohemia was a 12th-century archbishop of Salzburg and a member of the Premonstratensian order. Born around 1145 to Duke Vladislaus II of Bohemia and Gertrude of Babenberg, he was raised by his cousin, Emperor Frederick I Barbarossa. His tenure as archbishop occurred in two distinct stages, first from 1168 to 1177 and later from 1183 until his death in 1200. He is remembered primarily for the significant political and ecclesiastical conflicts he navigated with the Holy Roman Emperor.
