After having invaded and conquered Italy, King Otto I convokes a diet in Augsburg whereby he bestowed upon the defeated Berengar II and his son Adalbert the Kingdom of Italy, albeit somewhat reduced: the marches of Verona and Aquileia were ripped off from Italy and appended to the Duchy of Bavaria, governed by Otto's brother Henry. Since Istria formed part of the "March of Aquileia" (i. e. Friuli), this event marks the beginning of a new chapter of Istrian history.
Henry III, King of the Romans, donates properties in the March of Carniola and the County of Margrave Eberhard to the Church of Aquileia.
Henry IV, King of the Romans, donates properties in Piran and Novigrad in the March of Istria to the monastery of Saint Andrew in Freising under the jurisdiction of the Bishopric of Freising and its bishop Ellenhardus.
Notices from contemporary narrative sources regarding the Diet of Augsburg held in January 1209.
