The Turks, animated by this civil war which was raging in Germany, were pressing their march upon Hungary with great vigor, and the troops of Ferdinand were retiring discomfited before the invader.  Henry of France and the Duke of Parma were also achieving victories in Italy endangering the whole power of the emperor over those States.  Ferdinand, appalled by the prospect of the loss of Hungary, imploringly besought the emperor to listen to terms of reconciliation.  The Catholic princes, terrified in view of the progress of the infidel, foreseeing the entire subjection of Europe to the arms of the Moslem unless Christendom could combine in self-defense, joined their voices with that of Ferdinand so earnestly and in such impassioned tones, that the emperor finally, though very reluctantly, gave his assent to the celebrated treaty of Passau, on the 2d of August, 1552.  By this pacification the captives were released, freedom of conscience and of worship was established, and the Protestant troops, being disbanded, were at liberty to enter into the service of Ferdinand to repel the Turks.  Within six months a diet was to be assembled to attempt an amicable adjustment of all civil and religious difficulties.

The intrepid Maurice immediately marched, accompanied by many of the Protestant princes, and at the head of a powerful army, to repel the Mohammedan armies.  Charles, relieved from his German troubles, gathered his strength to wreak revenge upon the King of France.  But fortune seemed to have deserted him.  Defeat and disgrace accompanied his march.  Having penetrated the French province of Lorraine, he laid siege to Metz.  After losing thirty thousand men beneath its walls, he was compelled, in the depth of winter, to raise the siege and retreat.  His armies were everywhere routed; the Turks menaced the shores of Italy; the pope became his inveterate enemy, and joined France against him.  Maurice was struck by a bullet, and fell on the field of battle.  The electorate of Saxony passed into the hands of Augustus, a brother of Maurice, while the former elector, Ferdinand, who shortly after died, received some slight indemnification.

Such was the state of affairs when the promised diet was summoned at Passau.  It met on the 5th of February, 1555.  The emperor was confined with the gout at Brussels, and his brother Ferdinand presided.  It was a propitious hour for the Protestants.  Charles was sick, dejected and in adversity.  The better portion of the Catholics were disgusted with the intolerance of the emperor, intolerance which even the more conscientious popes could not countenance.  Ferdinand was fully aware that he could not defend his own kingdom of Hungary from the Turks without the intervention of Protestant arms.  He was, therefore, warmly in favor of conciliation.
