1 Ducat - Georg III, Ludwig IV and Christian

Georg III, Ludwig IV, and Christian ruled jointly over Liegnitz-Brieg as the last Piast dukes of Silesia — a dynasty that had governed the region since the thirteenth century. The Holy Roman Emperor had long sought to absorb Silesia more firmly into Habsburg control, and the joint reign of these three brothers was conducted under persistent imperial pressure to curtail Protestant rights and local autonomy. When Christian died in 1672 without a male heir, Emperor Leopold I invoked his reversion rights and absorbed the duchy directly, ending Piast rule in Silesia entirely.

Ducats of this type were struck across a nine-year window, and output varied considerably year to year depending on access to gold and the political stability of the ducal treasury.
