Berthold II of Zähringen, the son of the deposed duke of Carinthia, attacks the properties of St. Gallen monastery whose abbot is Ulrich Eppenstein, the brother of Liutold, the incumbent duke of Carinthia, and Henry, the incumbent margrave of Istria (narrative account from the contemporary chronicle Continuatio casuum sancti Galli).
Duke Henry Eppenstein renounces the advocacy over the Church of Aquileia in favor of his brother Ulrich, the incumbent patriarch of Aquileia, who invests the chapter of Aquileia with the rights of advocacy over their possessions and Burchard of Moosburg with the remaining rights of advocacy.
Henry of Eppenstein, duke of Carinthia, donates his castle "in the place that is called Ruvoyn" to the Church of Aquileia.
Pope Alexander III assumes the chapter of Aquileia and its canons under his protection and confirms all their possessions and jurisdictions.
