Johann Anton von Eggenberg held Krummau (Český Krumlov) as an autonomous duchy within Bohemia, one of the few such grants made directly by the Habsburgs to a non-royal family. The right to strike thalers was itself a privilege jealously administered by Vienna, and the Eggenbergs secured it as part of the extraordinary favor shown to Hans Ulrich von Eggenberg — Johann Anton's father — for services rendered during the Thirty Years' War. These thalers were struck across a five-year window that coincided almost exactly with the final, exhausted phase of that conflict, ending with the Peace of Westphalia in 1648.
The duchy itself was extinguished with the male line in 1717.
