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.

The discomfited Leopold swept back at the head of his mercenaries, 9000 foot and 3000 horse, through Alsace and along the Danube to Linz and so to Prague, marauding, harrying, and black-mailing the country as he went. He entered the city on the 15th of February 1611, fighting his way through crowds of exasperated burghers. Sitting in full harness on horseback in the great square before the cathedral, the warlike bishop compelled the population to make oath to him as the Emperor's commissary. The street fighting went on however day by day, poor Rudolph meantime cowering in the Hradschin. On the third day, Leopold, driven out of the town, took up a position on the heights, from which he commanded it with his artillery. Then came a feeble voice from the Hradschin, telling all men that these Passau marauders and their episcopal chief were there by the Emperor's orders. The triune city—the old, the new, and the Jew— was bidden to send deputies to the palace and accept the Imperial decrees. No deputies came at the bidding. The Bohemians, especially the Praguers, being in great majority Protestants knew very well that Leopold was fighting the cause of the Papacy and Spain in Bohemia as well as in the duchies.

And now Matthias appeared upon the scene. The Estates had already been in communication with him, better hopes, for the time at least, being entertained from him than from the flaccid Rudolph. Moreover a kind of compromise had been made in the autumn between Matthias and the Emperor after the defeat of Leopold in the duchies. The real king had fallen at the feet of the nominal one by proxy of his brother Maximilian. Seven thousand men of the army of Matthias now came before Prague under command of Colonitz. The Passauers, receiving three months pay from the Emperor, marched quietly off. Leopold disappeared for the time. His chancellor and counsellor in the duchies, Francis Teynagel, a Geldrian noble, taken prisoner and put to the torture, revealed the little plot of the Emperor in favour of the Bishop, and it was believed that the Pope, the King of Spain, and Maximilian of Bavaria were friendly to the scheme. This was probable, for Leopold at last made no mystery of his resolve to fight Protestantism to the death, and to hold the duchies, if he could, for the cause of Rome and Austria.

Both Rudolph and Matthias had committed themselves to the toleration of the Reformed religion. The famous "Majesty-Letter," freshly granted by the Emperor (1609), and the Compromise between the Catholic and Protestant Estates had become the law of the land. Those of the Bohemian confession, a creed commingled of Hussism, Lutheranism, and Calvinism, had obtained toleration. In a country where nine-tenths of the population were Protestants it was permitted to Protestants to build churches and to worship God in them unmolested. But these privileges had been extorted by force, and there was a sullen, dogged determination which might be easily guessed at to revoke them should it ever become possible. The House of Austria, reigning in Spain, Italy, and Germany, was bound by the very law of their being to the Roman religion. Toleration of other worship signified in their eyes both a defeat and a crime.

Thus the great conflict, to be afterwards known as the Thirty Years' War, had in reality begun already, and the Netherlands, in spite of the truce, were half unconsciously taking a leading part in it. The odds at that moment in Germany seemed desperately against the House of Austria, so deep and wide was the abyss between throne and subjects which religious difference had created. But the reserved power in Spain, Italy, and Southern Germany was sure enough to make itself felt sooner or later on the Catholic side.

Meantime the Estates of Bohemia knew well enough that the Imperial house was bent on destroying the elective principle of the Empire, and on keeping the crown of Bohemia in perpetuity. They had also discovered that Bishop-Archduke Leopold had been selected by Rudolph as chief of the reactionary movement against Protestantism. They could not know at that moment whether his plans were likely to prove fantastic or dangerous.

So Matthias came to Prague at the invitation of the Estates, entering the city with all the airs of a conqueror. Rudolph received his brother with enforced politeness, and invited him to reside in the Hradschin. This proposal was declined by Matthias, who sent a colonel however, with six pieces of artillery, to guard and occupy that palace. The Passau prisoners were pardoned and released, and there was a general reconciliation. A month later, Matthias went in pomp to the chapel of the holy Wenceslaus, that beautiful and barbarous piece of mediaeval, Sclavonic architecture, with its sombre arches, and its walls encrusted with huge precious stones. The Estates of Bohemia, arrayed in splendid Zchech costume, and kneeling on the pavement, were asked whether they accepted Matthias, King of Hungary, as their lawful king. Thrice they answered Aye. Cardinal Dietrichstein then put the historic crown of St. Wenceslaus on the King's head, and Matthias swore to maintain the laws and privileges of Bohemia, including the recent charters granting liberty of religion to Protestants. Thus there was temporary, if hollow, truce between the religious parties, and a sham reconciliation between the Emperor and his brethren. The forlorn Rudolph moped away the few months of life left to him in the Hradschin, and died 1612 soon after the new year. The House of Austria had not been divided, Matthias succeeded his brother, Leopold's visions melted into air, and it was for the future to reveal whether the Majesty-Letter and the Compromise had been written on very durable material.
