1 Thaler - Johann Christian and Georg Rudolf

Johann Christian and Georg Rudolf were the sons of Joachim Friedrich of Liegnitz-Brieg, and this joint-rule coinage reflects the peculiar dynastic arrangement that followed their father's death in 1602, when the two brothers governed the Silesian duchies of Liegnitz and Brieg in an uneasy co-regency. The Habsburgs had been tightening control over Silesia's semi-autonomous Protestant principalities throughout this period, and the brothers' ability to issue independent thalers was itself a quietly political act — one that would become increasingly difficult as the Thirty Years' War approached.

Georg Rudolf eventually ruled Liegnitz alone after 1621, but the joint issues from the pre-war decade, 1609 among them, are numerically scarcer than his later sole-reign output.
