The unhappy emperor was much piqued. He had been deprived by his brother of Hungary, Moravia, and Austria, while Matthias was now at Prague with an army, ostensibly to obtain ratification of the peace with Turkey, but in reality to force the solemn transfer of those realms and extort the promise of Bohemia. Could there be a better illustration of the absurdities of such a system of Imperialism? And now poor Rudolph was to be turned out of the Hradschin, and sent packing with or without his collections to the Tyrol. The bellicose bishop of Strassburg and Passau, brother of Ferdinand, had little difficulty in persuading the downtrodden man to rise to vengeance. It had been secretly agreed between the two that Leopold, at the head of a considerable army of mercenaries which he had contrived to levy, should dart into Julich as the Emperor's representative, seize the debateable duchies, and hold them in sequestration until the Emperor should decide to whom they belonged, and, then, rushing back to Bohemia, should annihilate Matthias, seize Prague, and deliver Rudolph from bondage. It was further agreed that Leopold, in requital of these services, should receive the crown of Bohemia, be elected King of the Romans, and declared heir to the Emperor, so far as Rudolph could make him his heir. The first point in the program he had only in part accomplished. He had taken Julich, proclaimed the intentions of the Emperor, and then been driven out of his strong position by the wise policy of the States under the guidance of Barneveld and by the consummate strategy of Maurice. It will be seen therefore that the Republic was playing a world's game at this moment, and doing it with skill and courage. On the issue of the conflict which had been begun and was to be long protracted in the duchies, and to spread over nearly all Christendom besides, would depend the existence of the United Netherlands and the fate of Protestantism.
