Pfennig - Dietrich

The Counts of Formbach held territory along the Inn River in what is now Lower Bavaria and Upper Austria, but the dynasty was effectively extinguished by the early twelfth century as lands passed through inheritance to the Counts of Andechs and later to the Babenbergs. Issues attributable to this window — tied to the name Dietrich — fall within the last coherent period of independent Formbach authority before that absorption was complete.
