Johann Weikhard held several positions at the Austrian court. From 1640, he was Obersthofmeister (Lord Chamberlain) and teacher of Ferdinand IV, who was King of the Romans at the time. In 1641 he was sent to The Hague and later he took part in peace negotiations at Osnabrück, which ultimately ended the Thirty Years’ War with the Peace of Westphalia (1648). In 1653, Emperor Ferdinand III raised him to Imperial Prince and in 1654, in his capacity as King of Bohemia, enfeofed him with the Duchy of Münsterberg and the City of Frankenstein. He then styled himself Duke of Münsterberg.
