Danish and Norwegian princess, the daughter of King Christian VI of Denmark and his wife Sophie Magdalene of Brandenburg-Kulmbach. Following her marriage to Ernest Frederick III, Duke of Saxe-Hildburghausen, she became Duchess of Saxe-Hildburghausen.
She disliked the strict customs at court; her father complained about her “rebellious nature” in a letter to his friend Count Christian Günther Stolberg.
Under her brother Frederik V’s reign in 1749, Louise had an affair—and possibly a child—with a valet de chambre from the noble Danish family Ahlefeldt, who was afterwards sentenced to imprisonment for his audacity in Munkholm Fortress. Later that year, she was hastily married to Ernest Frederick III, Duke of Saxe-Hildburghausen, with a large dowry to hasten the wedding and calm down the scandal. They married in the Hirschholm Palace, north of Copenhagen, on 1 October 1749.
As duchess of Saxe-Hildburghausen, she hosted a court known for its formal etiquette, great costs and many parties; she was described as proud and with “royal expenses” in her way of living, amusing herself with ballets, masquerades, balls, hunting and gambling, driving through the streets with a carriage (or, in winters, with a sleigh) of gold and silver.
She gave birth to a daughter, who died after a month: Princess Frederica Sophie Juliane Caroline (5 December 1755 – 10 January 1756). Louise died on 8 August 1756 at age 29 in Hildburghausen.
