But by ill luck this difficulty occurred at a time when the Emperor Rodolph was yet alive, and a spectator of this scene, and who might easily have been tempted to employ against his brother the same weapons which the latter had successfully directed against him -- namely, an understanding with his rebellious subjects. To avoid this blow, Matthias willingly availed himself of the offer made by Moravia, to act as mediator between him and the Estates of Austria. Representatives of both parties met in Vienna, when the Austrian deputies held language which would have excited surprise even in the English Parliament. "The Protestants," they said, "are determined to be not worse treated in their native country than the handful of Romanists. By the help of his Protestant nobles had Matthias reduced the Emperor to submission; where 80 Papists were to be found, 300 Protestant barons might be counted. The example of Rodolph should be a warning to Matthias. He should take care that he did not lose the terrestrial, in attempting to make conquests for the celestial." As the Moravian States, instead of using their powers as mediators for the Emperor's advantage, finally adopted the cause of their co-religionists of Austria; as the Union in Germany came forward to afford them its most active support, and as Matthias dreaded reprisals on the part of the Emperor, he was at length compelled to make the desired declaration in favour of the Evangelical Church. This behaviour of the Austrian Estates towards their Archduke was now imitated by the Protestant Estates of the Empire towards their Emperor, and they promised themselves the same favourable results. At his first Diet at Ratisbon in 1613, when the most pressing affairs were waiting for decision -- when a general contribution was indispensable for a war against Turkey, and against Bethlem Gabor in Transylvania, who by Turkish aid had forcibly usurped the sovereignty of that land, and even threatened Hungary -- they surprised him with an entirely new demand. The Roman Catholic votes were still the most numerous in the Diet; and as every thing was decided by a plurality of voices, the Protestant party, however closely united, were entirely without consideration. The advantage of this majority the Roman Catholics were now called on to relinquish; henceforward no one religious party was to be permitted to dictate to the other by means of its invariable superiority. And in truth, if the evangelical religion was really to be represented in the Diet, it was self-evident that it must not be shut out from the possibility of making use of that privilege, merely from the constitution of the Diet itself. Complaints of the judicial usurpations of the Aulic Council, and of the oppression of the Protestants, accompanied this demand, and the deputies of the Estates were instructed to take no part in any general deliberations till a favourable answer should be given on this preliminary point.
