Struggles in the war against German Protestantism. Since the beginning of the Reformation in Germany the views of the Bohemian reformers had undergone a considerable change. Some of the more advanced Utraquists differed but little from the German Lutherans, while the Bohemian Brethren, who at this moment greatly increased in influence through the accession of several powerful nobles, strongly sympathized with the Protestants of Germany. Ferdinand's task of raising a Bohemian army in support of his brother was therefore a difficult one. He again employed his usual tortuous policy. He persuaded the estates to vote a general levy of the forces of the country under the somewhat disingenuous pretext that Bohemia was menaced by the Turks; for at that period no armed force could be raised in Bohemia without the consent of the estates of the realm. Ferdinand fixed the town of Kaaden on the Saxon frontier as the spot where the troops were to meet, but on his arrival there he found that many cities and nobles--particularly those who belonged to the community of the Bohemian Brethren--had sent no men. Of the soldiers who arrived many were Protestants who sympathized with their German co-religionists. The Bohemian army refused to cross the Saxon frontier, and towards the end of the year 1546 Ferdinand was obliged to disband his Bohemian forces. Early in the following year he again called on his Bohemian subjects to furnish an army in aid of his brother. Only a few of the Romanists and more retrograde Utraquists obeyed his order. The large majority of Bohemians, on the other hand, considered the moment opportune for recovering the ancient liberties of Bohemia, on which Ferdinand had encroached in various ways by claiming hereditary right to the crown and by curtailing the old privileges of the land. The estates met at Prague in March 1547, without awaiting a royal summons,--undoubtedly an unconstitutional proceeding. The assembly, in which the influence of the representatives of the town of Prague and of the knights and nobles who belonged to the Bohemian Brotherhood was predominant, had a very revolutionary character. This became yet more marked when the news of the elector of Saxony's victory at Rochlitz reached Prague. The estates demanded the re-establishment of the elective character of the Bohemian kingdom, the recognition of religious liberty for all, and various enactments limiting the royal prerogative. It was decided to entrust the management of state affairs to a committee of twelve members chosen in equal number from the three estates. Of the members of the committee chosen by the knights and nobles four belonged to the Bohemian Brotherhood. The committee decided to equip an armed force, the command of which was conferred on Kaspar Pflug of Rabenstein (d. 1576). According to his instructions he was merely to march to the Saxon frontier, and there await further orders from the estates; there seems, however, little doubt that he was
