3 Kreuzers - Georg III, Ludwig IV and Christian

Georg III, Ludwig IV, and Christian ruled Liegnitz-Brieg as co-dukes under the inheritance arrangements that had fragmented Silesian Piast territories across multiple branches since the thirteenth century. By the 1650s, the duchy was operating under increasing pressure from the Habsburg administration in Vienna, which was systematically curtailing the rights of Silesian Protestant princes in the aftermath of the Thirty Years' War. All three dukes died without male heirs — Christian last, in 1672 — triggering the Habsburg escheatment of Liegnitz-Brieg that Ferdinand I had legally secured by treaty as early as 1537, a claim the Silesian Piasts had disputed for over a century.
