The king, who was at this time absent from Copenhagen, was however no stranger to the disgrace of this imprudent and noisy Wittenberg doctor. Christian had gone into the Netherlands, to meet his brother-in-law Charles the Fifth, for the purpose of treating with him of important matters. He easily changed his mind, as passionate men generally do; and amidst the splendor of the imperial court, he yielded to the influence of the new atmosphere which surrounded him. He wished the emperor to concede to him, as king of Denmark, the right of conferring the duchy of Holstein as a fief. The court bishops, on their side, implored Charles to make the expulsion of the Lutheran doctors the price of this favor. Christian, aware of all that he had to fear from the Pope, from Sweden, and even from a great number of the Danes, was anxious to conciliate the emperor that he might be able to face all his enemies. He therefore complied with the requirements of Charles. Carlstadt, as we have seen, was sent away from Denmark, and Reinhard never returned. For the reformation of Denmark Danes were required. Soon after the departure of Carlstadt, Tausen requested permission to teach at the university of Copenhagen, and he did actually lecture there on theology.[236] But no man could then carry a bright lamp without attempts being made to extinguish it. The teaching of the son of the peasant of Fionia aroused opposition; the professor was recalled by his prior, and remained for two years in his convent. Time was thus given him in his retirement to meditate; and while he was strengthening himself in the faith, great events were about to prepare the way for the Reformation. [Sidenote: Renewed Revolt Of The Swedes.] The concessions which Christian made to the enemies of the evangelical doctrines did not bring him any advantage. A violent storm at once broke out on all sides against the prince and threatened to overthrow him. Sweden revolted against him. Duke Frederick, his uncle, angry that his nephew wanted to make Holstein a fief of Denmark, entered into an alliance with the powerful city of Lübeck to fight against him. The prelates, also, and the nobles of Denmark, seeing that Christian was bent upon ruining them, formed a resolution to get rid of him. The blind docility with which Christian followed the counsels of Sigbrit provoked the grandees of the kingdom. Nothing was done except by the advice of this woman of very low origin. The king conferred benefits only on her favorites; and even political negotiations were discussed in her presence and left in her hands. The pride, the tyranny, and the passions of this old sorceress—for such was she called—excited the indignation of all classes of society. The people themselves were hostile to her, and many among the middle classes were on her account hostile to the king.
