An incident that took place at Donauworth,[3] a city near the Rhine, helped him to realise his scheme of a great Protestant federation.
This city was almost exclusively Catholic in 1555, but in one way or another the Protestants had succeeded in improving their position till at last only the abbey church remained to the Catholics. Here on the Feast of Corpus Christi in the year 1606 the customary procession of the Blessed Sacrament was attacked and dispersed, and the Catholics were treated with the greatest cruelty. When the matter was brought before the Emperor the city was placed under the ban of the empire, and Maximilian I. of Bavaria was entrusted with the task of carrying out the decree. He advanced with a strong army and captured the city.
As the war indemnity could not be raised he retained possession of it, restoring to the Catholics everything they had lost. Frederick IV.
made a strong appeal to the Protestant princes to show their resentment at such an act of aggression, pointing out to them that the fate of Donauworth would be the fate of all their territories unless they took united action. As a consequence when both parties met at the Diet of Regensburg (1608) the excitement was intense, and when the Emperor appealed to his princes for support against the Turks, the Protestants refused to lend their aid unless they received satisfactory explanations. The Catholics, encouraged by Maximilian, were equally unconciliatory, with the result that the Diet disbanded without having been able to arrive at an agreement.
A short time after the Diet most of the Protestant princes met at Ahausen and formed a confederation known as the /Union/ (1608) at the head of which stood Frederick IV. of the Palatinate, while a little later a large number of the Catholic princes bound themselves together in the /League/ and accepted Maximilian of Bavaria as their leader (1609). Thus Germany was divided once again into two hostile camps, and only a very trifling incident was required to plunge the country into another civil war. For a time it seemed as if the succession to the Duchy of Cleves was to be the issue that would lead to the catastrophe. Duke John William of Cleves had died without any direct heir, and as the religious issue was still undecided in his territory, the appointment of a successor was a matter of the greatest importance to both parties. The Emperor with the approval of the /League/nominated his brother Leopold as administrator, while the /Union/, having strengthened itself by an alliance with France, was prepared to take the field in favour of a Protestant. Henry IV. of France, anxious to turn the disputes that had broken out between the different members of the imperial family to the advantage of himself and his country, was actually on his way to take part in the campaign when he was assassinated. On his death both parties agreed to a temporary truce (1610), and thus the outbreak of the war was delayed for some time.
This delay was very fortunate for the Catholics in Germany. With such an Emperor as Rudolph pitted against a man like Henry IV. there could have been very little doubt about the issue. Even in his own territories Rudolph could not maintain his authority against his brother Matthias, in whose interest he was obliged to abdicate the throne of Bohemia (1611). On the death of Rudolph (1612) Matthias succeeded though not without considerable difficulty. As Emperor he showed himself much less favourable to the Protestants than he had been during the years when he was disputing with his brother, but, however well inclined, he was powerless to put an end to the division that existed or to control the policy of the /League/ or the /Union/.
The Duchy of Cleves was still an object of dispute. While the German Protestants invoked the aid of William of Orange and the Dutch Calvinists, the Catholics called in the forces of Spain. The Emperor could merely look on while his subjects allied themselves with foreigners to settle their own domestic troubles.
Meanwhile far more serious trouble was brewing in Bohemia, where the followers of Hus had blended with the disciples of Luther, and where in many centres there was a strong feeling against the Catholic Church. According to the concessions granted by Rudolph (1609), knights and free cities were at liberty to build Protestant churches, but a similar concession was not made to the subjects of Catholic lords. Regardless of or misinterpreting the terms of the concession, however, the Protestant tenants of the Archbishop of Prague and of the Abbot of Braunau built churches for their own use. The archbishop and abbot, considering themselves aggrieved, appealed to the imperial court. According to the decision of this court the church built on the lands of the archbishop was to be pulled down, and the other on the lands of the abbot was to be closed (1618). A deputation representing the Protestant party was appointed to interview the imperial representatives at Prague, and the reply to their remonstrances being regarded as unfavourable, the mob attacked the building, and hurled the councillors who were supposed to be responsible for it through the windows.
