In 1556, the Jews in the Papal States suffered a terrible persecution at the hands of the fanatical Pope Paul IV. This culminated in the imprisonment of all the Marranos or Crypto Jews of Ancona, and their sentence to the stake. At that time the most influential Jews in Europe were the Mendes or Nasi Family of Portugal and the Low Countries, the head of which was the famous Donna Gracia Nasi. Her son-in-law, who afterwards became Duke of Naxos in the service of the Porte, for whom he conquered Cyprus, was the Rothschild as well as the Disraeli of his day.[62] The Italian Jews sent piteous appeals to Donna Gracia, who was then settled in Constantinople. She at once addressed herself to the reigning Sultan, Solyman the Magnificent, and entreated his intervention, on the ground that the Marrano Jews in Ancona were for the most part Turkish subjects. The appeal was well conceived, for the Sultan was outraged by the idea that subjects of his could be maltreated by a foreign potentate. He promptly responded (March 9, 1556) by sending an ultimatum to the Pope, demanding the immediate release of his unjustly accused lieges, under pain of reprisals on the foreign Christians within his own dominions.[63] The Turk in those days was not in the habit of treating Christian States with an excess of ceremony, and the Pope realised the wisdom of complying with the ultimatum. He revenged himself, however, by burning those of the prisoners who could not be shown to be Turkish subjects.[64] This incident is of peculiar interest for its bearing on the still much debated question of the political status of Jews in the lands of their "Dispersion." The Turkish Jews in 1556 seem to have had no doubt that they were full nationals of the Ottoman Porte and as such entitled to the protection of the Turkish Sultan. The precedent, however, was far from decisive. In other circumstances other views have prevailed. Thus in 1655, when the Commonwealth declared war on Spain, and an order was issued for the confiscation of the property of Spaniards in England, some of the Spanish Crypto Jews, then resident in London, appealed against the order on the ground that their national status was that of Jews and not that of Spaniards. This plea was allowed by the Admiralty Commissioners, to whom it was referred, and they discharged the orders made against the appellants.[65]
