2 Ducats - Georg III, Ludwig IV and Christian

Georg III, Ludwig IV, and Christian ruled Liegnitz-Brieg jointly under the terms of the Piast inheritance arrangement that kept the duchy nominally intact while the Habsburgs steadily encroached on Silesian autonomy following the Thirty Years' War. The triple-portrait coinage issued during their co-regency — 1653 through Christian's death in 1672, though this type stops earlier — reflects a deliberate assertion of dynastic continuity at precisely the moment the Habsburgs were pressuring Protestant Silesian rulers hardest.

The Piast line in Liegnitz-Brieg died with Georg Wilhelm in 1675, at which point the Habsburgs absorbed the duchy directly, having long argued against the 1537 succession pact with Brandenburg. These joint-reign gold pieces are among the last numismatic expressions of an independent Silesian Piast court.
