This was the notorious Carnage of Stockholm. Secure in the thought that the Swedes were now cowed into submission, Christian II. returned to Denmark; but his dastardly deed had an unforeseen effect. A young nobleman, Gustavus Eriksson Wasa, whose father had been beheaded and who had himself been captured by Christian, escaped from his prison and became the deliverer of his country. The common indignation against the tyrant united once more all warring factions; the Danes were everywhere defeated, and Gustavus Wasa became first, regent, and later, king of Sweden (1523). From that time forth, the power of the Danes in Sweden was at an end. The failure of his plans abroad discredited Christian II. at home. His overweening self-esteem and impetuosity led him to commit rash acts, whereby he gave his enemies an advantage. Also in inaugurating reforms, which would have been beneficial, if they could have been carried into effect, he failed to measure the strength of the opposition which he would be sure to encounter. He issued a decree abolishing serfdom, encouraged commerce and industry, and hoped in the impending struggle to find support among the bourgeoisie and peasants, whose gratitude he had earned. Nor did he in this respect deceive himself. But long oppression had made the people timid, and their support was largely passive, and could not, without energetic leaders, be made to assert itself. The upper estates were yet too powerful. Christian had, by his devotion to Luther's teachings, also added the clergy to the number of his enemies, and by his championship of Dutch and native commerce he had incensed the Hansa. His uncle, Duke Frederick, of Holstein, took advantage of his many blunders, made alluring promises to the nobility, allied himself with the Hansa and began a war against his nephew. Christian summoned an assembly of notables to meet him at Viborg, but the nobles of Jutland, fearing that he might repeat the Carnage of Stockholm, sent him a letter, revoking their allegiance. Christian lost his courage, and instead of summoning the citizens to his support gathered all his treasures and fled to Holland (1523). Duke Frederick, of Holstein, now ascended the throne under the name of Frederick I. (1524-1533), and by the aid of the Danish nobleman, Vincentz Lunge, soon succeeded in gaining Norway. Sir Vincentz, who was a highly-cultivated but rapacious and unscrupulous man, had married the daughter of the Norse knight, Sir Nils Henriksson, whose wife, Inger Ottesdatter, was related to the old royal house. This remarkable woman, commonly known as Mistress Inger of Oestraat, played a prominent rôle in her day, but, unhappily, threw the weight of her wealth and influence on the side of the oppressors. One of her daughters married the Danish nobleman Erik Ugerup, another Nils Lykke, and a fourth was betrothed by her ambitious mother to a Swedish impostor who pretended to be a son of Steen Sture and a candidate for the Swedish throne.
