murdered with Ferdinand's connivance (December, 1551). The Turks thereupon began to advance, while the disputes of the Farnese in Italy, where France supported Orazio and the Emperor Ottavio, brought Henry II and Charles to the verge of war.
Under these circumstances men began to desert the Emperor's failing cause. Maurice, who had betrayed his cousin, would not adhere too scrupulously to Charles; he was highly unpopular in Saxony on account of his religious backsliding and his political treachery, and unless he found independent means of support he would go down with the Emperor's ruin; his own subjects were already thinking of placing his brother Augustus in his place, and his nobles declined to assist him in the siege of Magdeburg. So gradually he began to dissociate himself from the Emperor's fortunes; he supported Maximilian in his opposition to Philip's succession, and the Landgrave's sons in their attempt to secure some mitigation of their father's lot. He obtained in the autumn of 1550 a useful basis of operations, being entrusted by the Diet, in spite of the reluctance of Charles, who already suspected his intentions, with the conduct of the siege of Magdeburg. That city had been placed under the ban of the Empire for its continued resistance to Charles and to his religious measures; on September 22, 1550, its troops had been defeated by Duke George of Mecklenburg, but the citizens spurned all proposals for submission. Their indomitable resistance had stirred a fever of enthusiasm in Lutheran Germany; and the acceptance of the task of subduing them evoked renewed taunts of "Judas" against the Saxon usurper.
But it was not Protestantism which Maurice intended to betray this time. His character remains to this day an enigma; elaborate attempts have been made to represent him not merely as the ablest statesman of his age but as the champion of German Protestantism, consistently working in its interest. According to this theory his original desertion of the Schmalkaldic League was only a necessary step towards his ultimate victory over Charles and the forces of reaction. To others his career appears to be a masterpiece of treachery, and Maurice himself a subtle intriguer comparable only with his contemporary the Duke of Northumberland, who like him played an unscrupulous and selfish part under the mask of religion. In Maurice the territorial ambition of German Princes found its most skilful exponent: his religious creed was but an accident of circumstances. No pronounced Catholic could have maintained himself in ducal Saxony or held the Ernestine electorate; but Charles' help was indispensable for the overthrow of John Frederick, and Charles' help could not be purchased without some concessions to orthodoxy. This object having been achieved Maurice proceeded to rid himself of a dangerously unpopular ally; and he was as successful in choosing the right moment for leaving Charles as he had been when he deserted the Schmalkaldic League.
