Pope Urban III
The Patriarchate subsequently extended its political control in the area: regions under Aquileian control in the following centuries included the Friulian lands up to Cadore, the city of Trieste and the central parts of the Istrian peninsula. At its maximum height, the Patriarchate of Aquileia was one of the largest states in Italy. Noblemen from the Patriarchate were participants in the Crusades. In 1186 Patriarch Godfrey crowned Frederick Barbarossa's son, Henry VI, as King of Italy: in retaliation, Pope Urban III deposed him.
