At the same time the Norwegians also revolted. The most powerful man in Norway at that time was Sir Knut Alfson, owner of Giske and many other estates. He had long been commander at Akershus; but had had a quarrel with Henrik Krummedike, the commander at Bahus, and the king, suspecting him of being friendly to the Swedes, had removed him. Now that the Swedes had revolted, Sir Knut joined them and defeated the Danes, after which he invaded Norway and captured the fortresses Akershus and Tunsberghus. Henrik Krummedike proceeded with a strong army to Oslo, in order to besiege Akershus. Negotiations were opened for peace, and Henrik invited Sir Knut to a conference on board his ship under safe conduct, but, on his arrival, foully murdered him and threw his body into the water. The struggle of the discontented Norwegians was continued under the leadership of Knut Alfson's widow, the brave Lady Mette Dyre; but when the Danes received reinforcements from Denmark the rebellion was soon suppressed, and Lady Mette was obliged to flee to Sweden. Knut Alfson's large estates were confiscated to the crown. The attempt to subdue the Swedes was not so successful, although some strong attacks were made. The able regent, Sten Sture, died in 1503, but his successor, Svante Nilsson Sture, who married Knut Alfson's widow, defended his country's independence with courage and ability. He died in 1512, and was succeeded by Sten Sture the Younger. In the year 1506 King Hans sent his son Christian to Norway to rule the country in his name. Christian tried to rule as an autocratic king, and to place Norway entirely under Danish rule. He installed Danes as commanders of the fortresses, and also had Danes elected bishops. His faithful servant and chancellor, Erik Valkendorf, was made archbishop in Throndhjem. He understood that it was detrimental to the country that the Hansa towns had a monopoly of the trade, and therefore tried to restrict their privileges and to encourage the competition by the merchants from Holland, and took many steps to help the Norwegian towns. But in dealing with revolts he was very severe. An uprising by the peasants of Hedemarken, under the leadership of Herlog Hudfat, was promptly crushed, and the leaders were beheaded outside of Akershus. Some of the captured peasants were tortured until they confessed that Bishop Carl of Hamar was the real instigator of the rebellion. The bishop was captured and held in prison until his death, and Christian took possession of his estate.
