Frederick VI was the last king of Denmark-Norway. During his reign a woman’s well preserved body was discovered in a peat bog, and Frederick claimed it was that of Queen Gunnhild. Frederick’s wikipedia article states:
After the discovery of the Haraldskær Woman in a peat bog in Jutland in the year 1835, Frederick VI ordered a royal interment in an elaborately carved sarcophagus for the Iron Age mummy, decreeing it to be the body of Queen Gunnhild. Later this identification proved incorrect, but the action suited his political agenda at the time.
Unfortunately that source link is dead, and the magazine it linked to has only a short article on the bog body. Frederick’s entry in Britannica states:
Frederick, in 1834, set up four consultative provincial assemblies. This action marked the beginning of parliamentary life in Denmark.
Those assemblies were formed only a year before the body was found. Based on other biographies it sounds like the monarchy was in decline at the time of his reign. If the country was trending towards a parliamentary system, did Frederick claim the body was a queen in an attempt to strengthen the monarchy’s image? What were his political motivations for this claim?
