Foremost among the peacemakers was the Archbishop of Köln; but unfortunately he was too much in advance of his age to produce the results which a more commonplace politician might have accomplished. He proposed a scheme of universal disarmament, and he suggested the reference of the Jülich controversy to the arbitration of the Universities. These proposals were cut short by a new outbreak of war between some of the claimants to the Jülich estate; while the assassination of Henry IV. once more raised the hopes of Rudolf and his friends, and made them disinclined to concession. But others besides the Archbishop of Köln desired to reconcile Rudolf to Matthias; and in spite of evasions and resistances, Rudolf was forced, in September, 1610, to recognise his brother as holding under him the lands of Hungary, Moravia, and Austria. This concession was, if possible, even less honest in intention than the confirmation of the Letter of Majesty had been; for the coldness with which he had been treated by the princes of the Empire had made Rudolf even more inclined than before to throw himself into the dangerous plans of the Archduke Leopold. Even while the Convention of Princes was sitting and the negotiations with Matthias were proceeding, Leopold was raising troops in the Bavarian district of Passau, and by the time that the agreement was concluded this force had grown to a considerable size. Peter Vok of Rosenberg had called attention to the danger incurred by his town of Krumov through the neighbourhood of these soldiers; and the Bohemian Assembly demanded that, since peace had now been made, this force should be disbanded. Rudolf pleaded that he could not yet dismiss them, because he had no money for the payment of their wages; and he proposed that, to secure them better quarters, they should be sent to Krumov and Budweis (Budejóvice). The Bohemian Assembly indignantly protested against the introduction of foreign troops into their country, and they refused to vote any money for their support.
