Louis I, Grand Duke of Hesse
In 1776, he became engaged to Sophie Dorothea of Württemberg, eldest daughter of Frederick II Eugene, Duke of Württemberg. The engagement was broken off so that Sophia Dorothea could marry Louis's recently widowed brother-in-law Tsarevich Paul Petrovich, son and heir of Catherine II "the Great", Empress of Russia. He received a monetary compensation when the engagement was broken.
Sophie Magdalene of Brandenburg-Kulmbach
King Frederick IV of Denmark allowed his son, Crown Prince Christian, to find a suitable bride. During a trip through Europe accompanied by Chancellor Ulrik Adolf Holstein the Crown Prince met Sophie Magdalene while she was serving as lady-in-waiting of the Queen of Poland at the Pretzsch Castle. She came from a small (the Margraviate of Kulmbach was not greater than Lolland-Falster), insignificant, relatively poor and large German princely family (she had 13 siblings); however, the King gave his permission. In the Crown Prince's letters he wrote that he fell for Sophie Magdalene's intense religiosity, which matched with his own beliefs. It would affect his later reign. The wedding took place on 7 August 1721 at Pretzsch Castle in Saxony.
