After the death of Augustus of Saxony in February 1586 there was another brief alliance between the Protestant parties, although on this occasion the lead was taken not by the Saxon, but by the Palatine prince. Less strict in his adherence to the tenets of Lutheranism than Augustus, the new elector of Saxony, Christian I., fell under the influence of John Casimir. The result was that Protestant princes, including the three temporal electors, united in placing their grievances before the emperor; obtaining no redress they met at Torgau in 1591 and offered help to Henry IV. of France, a proceeding which was diametrically opposed to the past policy of Saxony. But this alliance, like its forerunner, was of very short duration. Christian I. died in 1591, and under Christian II. electoral Saxony re-established a rigid Lutheranism at home and pursued a policy of moderation and neutrality abroad. A short time afterwards the militant party among the Protestants suffered a heavy loss by the death of their leader, John Casimir, whose policy, however, was continued by his nephew and pupil, the elector Frederick IV. But neither desertion nor death was able to crush entirely the militant Protestants, among whom Christian, prince of Anhalt (1568-1630), was rapidly becoming the most prominent figure. They made themselves very troublesome at the diet of Regensburg in 1593, and also at the diet held in the same city four years later, putting forward various demands for greater religious freedom and seeking to hinder, or delay, the payment of the grant for the Turkish war. Moreover, in 1598 they put forward the theory that the vote of a majority in the diet was not binding upon the minority; they took up the same position at Regensburg in 1603, when they raised strong objections to the decisions of the _Reichshofrat_ and afterwards withdrew from the diet in a body. Thus, under Maximilian of Bavaria and Christian of Anhalt respectively the two great parties were gaining a better idea of their own needs and of each other's aims and were watching vigilantly the position in the duchies of Cleves, Jülich and Berg, where a dispute over the succession was impending. While wars and rumours of wars were disturbing the peace in the west of Germany the Turks were again harassing the east. The war between them and the Empire, which was renewed in 1593, lasted almost without interruption until November 1606, when peace was made, the tribute long paid by the emperor to the sultan being abandoned. This peace was concluded not by Rudolph, but by his brother, the archduke Matthias, who owing to the emperor's mental incapacity had just been declared by his kinsman the head of the house of Habsburg. Rudolph resented this indignity very greatly, and until his death in January 1612 the relations between the brothers were very strained, but this mainly concerns the history of Hungary and of Bohemia, which were sensibly affected by the fraternal discord.
