The princess was named for her maternal grandmother. She was baptised with the names Caroline Mathilde Louise Dagmar Christine Maud Augusta Ingeborg Thyra Adelheid and was known as 'Calma' to her family.[2]
Not wanting to play a prominent public role, the princess led a relatively quiet life. She was involved in various charitable work, most prominently in support of the Danish minority in Germany.[5]
From 1947 to 1953, Prince Knud was heir presumptive of his older brother King Frederik IX. Knud would have become king and Caroline Mathilde queen in their turn, but a change in the constitution in 1953 caused Knud to lose his place in the succession to his niece, Margrethe II. After the change, Prince Knud was given the title of Hereditary Prince and Caroline Mathilde became Hereditary Princess.
Hereditary Prince Knud died on 14 June 1976. Hereditary Princess Caroline Mathilde survived her husband by 19 years and died on 12 December 1995 at Sorgenfri Palace.[5] She was interred next to her husband in Roskilde Cathedral on the island of Zealand, the traditional burial site for Danish monarchs since the 15th century.[8]
