contributions by Olaus Petri, a Swedish clergyman. Friction with the pope over the latter's interference in Swedish ecclesiastical affairs led to the discontinuance of any official connection between Sweden and the papacy since 1523. Four years later, at the Diet of Västerås, the king succeeded in forcing the diet to accept his dominion over the national church. The king was given possession of all church property, church appointments required royal approval, the clergy were subject to the civil law, and the "pure Word of God" was to be preached in the churches and taught in the schools—effectively granting official sanction to Lutheran ideas. The apostolic succession was retained in Sweden during the Reformation. The adoption of Lutheranism was also one of the main reasons for the eruption of the Dacke War, a peasants uprising in Småland. Finland Denmark Under the reign of Frederick I (1523–33), Denmark remained officially Catholic. Frederick initially pledged to persecute Lutherans, yet he quickly adopted a policy of protecting Lutheran preachers and reformers, of whom the most famous was Hans Tausen. During his reign, Lutheranism made significant inroads among the Danish population. In 1526, Frederick forbade papal investiture of bishops in Denmark and in 1527 ordered fees from new bishops be paid to the crown, making Frederick the head of the church of Denmark. Frederick's son, Christian, was openly Lutheran, which prevented his election to the throne upon his father's death. In 1536, following his victory in the Count's War, he became king as Christian III and continued the Reformation of the state church with assistance from Johannes Bugenhagen. By the Copenhagen recess of October 1536, the authority of the Catholic bishops was terminated. Faroe Islands Iceland Luther's influence had already reached Iceland before King Christian's decree. The Germans fished near Iceland's coast, and the Hanseatic League engaged in commerce with the Icelanders. These Germans raised a Lutheran church in Hafnarfjörður as early as 1533. Through German trade connections, many young Icelanders studied in Hamburg. In 1538, when the kingly decree of the new Church ordinance reached Iceland, bishop Ögmundur and his clergy denounced it, threatening excommunication for anyone subscribing to the German "heresy". In 1539, the King sent a new governor to Iceland, Klaus von Mervitz, with a mandate to introduce reform and take possession of church property. Von Mervitz seized a monastery in Viðey with the help of his sheriff, Dietrich of Minden, and
