The severest blow dealt by Francis against the heretics of his kingdom fell upon the Vaudois, or Waldenses, [Footnote: So called from the founder of the sect, Peter Waldo, or Pierre de Vaux, who lived about the beginning of the thirteenth century.] the inhabitants of a number of hamlets in Piedmont and Provence. Thousands were put to death by the sword, thousands more were burned at the stake, and the land was reduced to a wilderness. Only a miserable remnant, who found an asylum among the mountains, were left to hand down their faith to later times.

CHARLES' WARS WITH THE PROTESTANT GERMAN PRINCES.—Charles, on his part, turned his attention to the reformers in Germany. Inspired by religious motives and convictions, and apprehensive, further, of the effect upon his authority in Germany of the growth there of a confederacy of the Protestant princes, known as the League of Schmalkald, Charles resolved to suppress the reform movement by force. He was at first successful, but in the end, the war proved the most disastrous and humiliating to him of any in which he had engaged. Successive defeats of his armies forced him to give up his undertaking to make all his German subjects think alike in matters of religion.

THE RELIGIOUS PEACE OF AUGSBURG (1555).—In the celebrated Diet of Augsburg, convened in 1555 to compose the distracted affairs of the German states, it was arranged and agreed that every prince should be allowed to choose between the Catholic religion and the Augsburg Confession, [Footnote: The "Augsburg Confession" was the formula of belief of the adherents of Luther. It was drawn up by the scholar Melanchthon, and laid before the Imperial Diet assembled at Augsburg by Charles V. in 1530.] and should have the right to make his religion the worship of his people. This, it will be noted, was simply toleration as concerns princes or governments. The people individually had no freedom of choice; every subject must follow his prince, and think and believe as he thought and believed. Of course, this was no real toleration.

Even to the article of toleration as stated above, the Diet made one important exception. The Catholics insisted that ecclesiastical princes, i.e., bishops and abbots who were heads of states, on becoming Protestants, should lose their offices and revenues; and this provision, under the name of the Ecclesiastical Reservation, was finally made a part of the treaty. This was a most fortunate article for the Catholics.

ABDICATION AND DEATH OF CHARLES.—While the Diet of Augsburg was arranging the Religious Peace, the Emperor Charles was enacting the part of a second Diocletian (see p. 331). There had long been forming in his mind the purpose of spending his last days in monastic seclusion. The disappointing issue of his contest with the Protestant princes of Germany, the weight of advancing years, together with menacing troubles which began "to thicken like dark clouds about the evening of his reign," now led the emperor to carry this resolution into effect. Accordingly he abdicated in favor of his son Philip the crown of the Netherlands (1555), and that of Spain and its colonies (1556), and then retired to the monastery of San Yuste, situated in a secluded region in the western part of Spain (1556).

Lizcano.)]

In his retreat at Yuste, Charles passed the remaining short term of his life in participating with the monks in the exercises of religion, and in watching the current of events without; for Charles never lost interest in the affairs of the empire over which he had ruled, and Philip constantly had the benefit of his father's wisdom and experience.

There is a tradition which tells how. Charles, after vainly endeavoring to make some clocks that he had about him at Yuste run together, made the following reflection: "How foolish I have been to think I could make all men believe alike about religion, when here I cannot make even two clocks keep the same time."

This story is probably mythical. Charles seems never to have doubted either the practicability or the policy of securing uniformity of belief by force. While in retirement at Yuste, he expressed the deepest regret that he did not burn Luther at Worms. He was constantly urging Philip to use greater severity in dealing with his heretical subjects, and could scarcely restrain himself from leaving his retreat, in order to engage personally in the work of extirpating the pestilent doctrines, which he heard were spreading in Spain.
