Pfennig - Henry IV Windischgrätz

Henry IV of Windischgrätz held authority over Carniola during a period when the March was caught between competing pressures from the Duchy of Austria and the Patriarchate of Aquileia. Local pfennig coinage of this type — thin, bracteate-influenced silver struck in the Friesacher tradition — circulated widely across the Alpine-Adriatic trading routes connecting the Adriatic coast to the Danube basin. The Friesacher pfennig system, developed in Carinthia from the late twelfth century, had by Henry's time become the dominant monetary medium across much of the eastern Alpine region, with imitations and regional variants proliferating rapidly.
