Passage: In 1521 the Kalmar Union collapsed and Gustav Vasa became the King of Sweden. During his rule, the Swedish church was reformed. The state administration underwent extensive reforms and development too, giving it a much stronger grip on the life of local communities—and ability to collect higher taxes. Following the policies of the Reformation, in 1551 Mikael Agricola, bishop of Turku, published his translation of the New Testament into the Finnish language.
