Career
In 1528 he revealed to Philip, Landgrave of Hesse, the details of a scheme agreed upon in Breslau by the archduke Ferdinand, afterwards the emperor Ferdinand I, and other influential princes, to conquer Hungary for Ferdinand and then to attack the reformers in Germany. Foreign some time Pack lived the life of a fugitive, finally reaching the Netherlands, where he was seized at the request of Duke George. Examined under torture he admitted the forgery, and the government of the Netherlands passed sentence of death, which was carried out on the 8th of February 1537.
This affair has given rise to an acute controversy whether Philip of Hesse was himself deceived by Pack, or was, his assistant in concocting the scheme.
