Struve has remarked that of all the nobles in the world those in the Hapsburg Monarchy had probably the least reason to boast of their ancestry. This is especially true of the nobility whose advent into Bohemia antedates the first half of the seventeenth century. From the events here related began the rise in Bohemia of such families as Buquoy, Clary de Riva, Aldringen, Trautmansdorff, Metternich, Marradas, Verduga, Colloredo, Piccolomini, Wallis, Gallas, Millesimo, Liechtenstein, Goltz, Villani, Defours, Huerta, Vasques--names indicating Spanish, Italian, German, and Walloon birth. These aliens, enriched by property taken away from Bohemian nobility, surrounded themselves with foreign officials, who treated the natives with the scorn and insolence of victors. Their châteaux formed in many cases the nucleus of German settlements which later threatened to overwhelm the nation. Some of these “islands,” or settlements, which were situated farther inland, were in time absorbed by the native population. But not so with the colonies on the border. These latter not only preserved the lingual and national characteristics of the owners, but they even contrived to Germanize the home element that came into contact with them. It was during this calamitous period that the Germans made the greatest inroads upon Bohemian national territory. Prior to the Thirty Years’ War Bohemia was overwhelmingly Protestant,[5] but Ferdinand determined that in his empire there should be “unity of faith and tongue.” A unity of faith he and his successors have achieved, but it has been denied to the Hapsburgs--much as they have tried to achieve it--the unity of language. In 1620 Jesuit fathers were invited to come to Bohemia and to take charge of the once renowned University of Prague and of the provincial schools. “The Jesuits buried the spirit of the Bohemian nation for centuries.” This is the severe judgment of no less a person than V. V. Tomek, the noted historian. Accompanied by Liechtenstein’s dragoons these ecclesiastics went from town to town, searched libraries, carried off books written in Bohemian and burned them whether they were “tainted” or not. Sometimes the books were privately thrown in the flames in the houses where they had been seized; at other times they were brought to the market-place or to the public gallows and there publicly burned. The Jesuits were indefatigable in their search for heretical literature, ransacking houses from cellar to garret, opening every closet and chest, prying into the very dog kennels and pig-sties. People hid their most precious books from the ferreting eyes of the inquisitioners in baking ovens, cellars, and caves. There are cases on record of rare Bohemian volumes having been saved from destruction by being hidden under manure piles.
