some of the nobles of Meissen, a part of Saxony which was mainly Albertine but to some extent under Ernestine influence. The Catholic Bishop of Meissen naturally sided with Maurice, who had succeeded to his father in 1541, rather than with John Frederick. In 1542 he demurred to the Elector's demand for levies for the Turkish war, and John Frederick without consulting his cousin marched his troops into Würzen, the property of a collegiate chapter founded by the Bishops of Meissen, and conveniently situated for incorporation in the Elector's dominions. This inflamed the Albertine nobility, and Maurice began to arm. The Landgrave and Luther intervened; a compromise was patched up, and Würzen was partitioned; but a root of bitterness remained between the cousins, which bore fruit in later years.
One aggression was promptly followed by another. Among the temporal Catholic Princes none of note were left except the Dukes of Bavaria and Duke Henry of Brunswick. Duke Henry (Luther's "böser Heinz") was described as the "greatest Papist in all Germany, 1" and he was left alone in the north to face the Schmalkaldic League. He had long been at enmity with Philip of Hesse, and his cruelty towards his wife was almost as great a scandal as the Landgrave's bigamy. In his zeal for his faith or for his house he pronounced Charles' suspension of the verdicts of the Reichskammergericht against Brunswick and Goslar to be contrary to the laws of the Empire, and despite the disapprobation of Ferdinand, Granvelle, and Albrecht of Mainz, he proceeded to attack the two towns. The Schmalkaldic League at once armed in their defence; but not satisfied with this the Elector and the Landgrave overran Henry's duchy, Wolfenbüttel alone offering serious resistance (August, 1542). The Duke's territories were sequestered by the League and evangelised by Bugenhagen. Ferdinand had to content himself with the League's assurance that it would carry the war no farther, and with the pretence that it had been waged in defence of Charles' suspending powers. But the sort of respect the Lutherans were willing to pay the imperial authorities was shown by their attitude towards the Kammergericht. They obtained admittance to it early in 1542, and thereupon declined to tolerate the presence of any clerical colleagues; but, failing to secure a majority on it, they declared in December that it had no jurisdiction over them or their allies. Encouraged perhaps by the result of the Brunswick war, Duke William of Cleves now abandoned his Erasmian compromise and adopted Lutheranism undefiled. Even more important was the simultaneous conversion of Hermann von Wied, Archbishop and Elector of Cologne, whose territories were surrounded on all sides by the composite duchy of Cleves-Jiilich-Berg. Bishop Hermann had held the see since 1515; he had corresponded with Erasmus, and after 1536 had endeavoured to reform the worst practical abuses in his diocese. Gropper's treatise, written to reconcile justification by faith with Catholic doctrine, probably indicates the direction in which the Archbishop's mind
