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.

She married on 24 February 1555 in Wismar to Duke John Albert I of Mecklenburg (1525-1576). As a wedding gift, her father mediated in a dispute between her husband and his brother Ulrich, Duke of Mecklenburg.
