卡爾十三世
In 1774, the King arranged the marriage between his brother, the future Charles XIII of Sweden, and Hedwig Elizabeth Charlotte of Holstein-Gottorp, to solve, for the time being, the immediate question of an heir to the throne. The Duchess had false pregnancies and miscarriages only, which may have hastened the King to expedite the consummation of his own marriage and produce a son of his own.
