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.
Sophia of Denmark
According to "Erikskrönikan", the wedding between Sophia and Valdemar took place in 1260 at Ymninge (likely Öninge in Ödeshög), and was described as a grand event with tournaments, dance, games and poetry. Sophia was given the income from Malmö and Trelleborg as well as a fortune in gold and silver as her dowry. However, her position at the wedding was already somewhat less fortunate than when the engagement was announced. Her father-in-law Birger Jarl himself married her uncle Abel's widow, Denmark's queen dowager Matilda of Holstein, and Sophia was thereby given the widow of her uncle Abel, pointed out as her father's murderer, as her mother-in-law. At the time of her wedding, her uncle Christopher I was succeed by Eric V of Denmark under the regency of Margaret Sambiria, who refused to acknowledge Sophia's right to the inheritance after her father until 1263.
