Two years later the same city of Lübeck was called upon to arbitrate in a conflict between the two kings, which it thus had made, Frederick of Denmark and Gustavus of Sweden. As the price of its intervention and of the sacrifices it had made on their behalf, the city, in the name of the League, of course, asked great favours, favours which were accorded by treaty, and which were to be the last smiles of Fortune, about to become fickle to the union she had favoured so long.

Meanwhile, in June, 1523, Gustavus Vasa had been, by unanimous consent, elected King of Sweden. It is amusing to read that Stockholm, the last city to surrender to its new ruler, the last faithful to Christian, refused, even after it had capitulated, to deliver up the keys of the gates to Gustavus. The governor handed them over to two Lübeck councillors, present on the occasion, with the words, "We present to the imperial city of Lübeck the kingdom and the city, and not to that rogue, Gustavus Erikson, who stands there."

It must not be supposed, however, that Christian so quietly and easily abandoned his Danish crown to his uncle and rival. He made many attempts to enlist the various courts in his favour. Especially did he try to gain the help of his brother-in-law, the emperor, but the League was too clever and too strong for him. He did get together an army of mercenaries, but his means of paying them soon ran out, though to attain that end he pawned or sold all his treasures and the queen's jewels. At last, he had to fly in terror from his own soldiers who were enraged at his inability either to pay them their wages, or at least lead them to some town they could plunder.

Nevertheless, Christian was not daunted. He was a man not easily dismayed. He intrigued on every hand to regain his kingdom, and at last, fancying that the Lutheran doctrines he had embraced prejudiced the emperor against him, he formally renounced Protestantism and returned into the bosom of the Romish Church.

Christian had not erred in his calculations. This step induced Charles to be more favourable to him, and for a while he lent him his countenance, soon, however, to withdraw it. Still the brief favour sufficed to enable him to get together a strong army to attack Denmark. Frederick, alarmed, turned to Lübeck for aid, and did not turn in vain. Indeed, his ambassadors admitted that "Lübeckers had shown themselves in this time of need, not like mere neighbours, but like fathers to Denmark."

After many vicissitudes of fortune, Christian at last abandoned the idea of regaining his old rights by force of arms. He craved an interview with his uncle and a free passage to Copenhagen. This safe passage was accorded to him and its terms were couched in the most sacred and solemn words. The Hanseatic representatives enforced the promise on their own account. Not suspecting treachery, unwarned, Christian stepped on board the vessel that was to convey him to the Danish capital, and arrived in Copenhagen with the fond hope that Frederick would receive him like the prodigal son. Instead of allowing him to land at once, however, he was detained in the harbour for five days, under the pretext that Frederick was absent, and at last when permitted to set foot on dry land, he was invited to meet the king at Flensburg, and was told that the fleet had orders to carry him thither.

Then, and only then, the unfortunate man suspected that he had been betrayed. And so it was. Frederick and his councillors pronounced the safe conduct null and void; Christian was taken prisoner, and amid fierce ejaculations of rage and despair, was locked up in the "Blue Tower" of the Castle of Sonderburg. Here for fifteen years in company with his favourite dwarf, Christian had to suffer painful confinement that only ended with his death. His confinement was unjust, no doubt, but it was richly merited.

Unmourned by his relations, or the aristocracy he had oppressed, Christian's memory lived among the peasants and lower classes, of whom he had been the supposed friend, a friendship that no doubt had no higher aim than his own ends, but which never had occasion to show its true character. His name, consequently, became a watchword among the people, and inspired those who soon after were to be the leaders in great convulsions in the Scandinavian provinces. But this is outside the course of my history.
