Jean Sibelius composed in 1898 incidental music "King Christian II" to a play about the king, and derived from it a suite. Christian II had six children by his wife, Isabella of Austria (1501–1526), only three of whom survived infancy and two reached adulthood. They were:  His daughters, Electress Palatine Dorothea and Christina, Duchess of Milan, both in turn, for many years, demanded in vain the Danish and Norwegian thrones as their inheritance, although these kingdoms were nominally elective monarchies. However, Christian II's blood was not to return to the Swedish and Norwegian thrones until 1859, in the person of Charles XV of Sweden, whose grandmother Princess Augusta of Bavaria, was descended from Magdalene of Bavaria, the great-great granddaughter of Christian II.
