It was also in the interest of allaying the animosity against his own person that Elector Maurice had prevailed upon Melanchthon to frame the Leipzig Interim. But in this respect, too, the document proved to be a dismal failure. Openly the people, his own former subjects included, showed their contempt for his person and character. Everywhere public sentiment was aroused against him. He was held responsible for the captivity and shameful treatment of Philip of Hesse and especially of John Frederick, whom the people admired as the Confessor of Augsburg and now also as the innocent Martyr of Lutheranism. Maurice, on the other hand, was branded a mameluke, condemned as a renegade and an apostate, despised as the traitor of Lutheranism, and abhorred as the "Judas of Meissen," who had sold his coreligionists for an electorate. At the same time Maurice was provoked by the arbitrary manner in which the Emperor exploited and abused his victory by a repeated breach of his promises, and by the treacherous and shameful treatment accorded his father-in-law, Philip of Hesse. Chagrined at all this and fully realizing the utter impossibility of enforcing the Interim, Maurice decided to end the matter by a single stroke which at the same time would atone for his treachery, and turn shame into glory and the vile name of a "traitor" into the noble title of "Champion of Protestantism." Accordingly Maurice, easily the match of Charles in duplicity and cunning, secretly prepared his plans, and, suddenly turning his army against the unsuspecting Emperor, drove him from Innsbruck, scared the "Fathers of Trent" to their homes, and on April 5, 1552, victoriously entered Augsburg, where he was received with great rejoicing. The fruits of this victory were the Treaties of Passau August 2, 1552, and of Augsburg, 1555, which for the first time granted religious liberty to the Protestants. The latter placed Lutherans and Catholics on an equal footing in the Empire and, according to the rule: _Cuius regio, eius religio,_ gave every prince religious control in his own territory, non-conformists being granted the right of emigration. To the great advantage of the Romanists, however, the treaty also provided that territories ruled by bishops must remain Catholic even though the ruler should turn Protestant.
