Prince Charles was born on 26 October 1680 at Copenhagen Castle as the fourth son of Christian V and his consort Queen Charlotte Amalie. As was the tradition at the court, his upbringing was left to others, including Johan Georg Holstein, who was replaced by Carl Ahlefeldt as his hofmeister in 1696. In particular Christian Siegfried von Plessen was charged with his upbringing. Prince Charles suffered from weak health and was hard of hearing. In order to benefit from a milder climate he was sent to France and Italy on a study trip from 1696 to 1699, spending most of the time in Montpellier. On the journey he was accompanied by Carl Adolph von Plessen, the son of his mentor, and only three years his senior. Von Plessen would remain a close friend and companion of the prince for the rest of his life, with title of first hoffmeister and later chamberlain. Prince Charles was never married. Between 1697 and 1699, there was a Danish policy to create an alliance with Sweden through a double wedding between Charles XII of Sweden and Princess Sophia Hedwig of Denmark, and Prince Charles of Denmark and Hedvig Sophia of Sweden. However, none of the marriages was materialized.
Back in Denmark Prince Charles settled at Jægerspris Castle which he was given by his older brother, now King Frederick IV of Denmark since his ascent to the throne. He immediately embarked on a major extension of the castle and passionately fond of horses, an interest he shared with his father and brother, he also founded a stud farm on the estate. From his mother, who died in 1715, he inherited Vemmetofte Manor and Højstrup Manors on Zealand and Charlottenborg Palace in Copenhagen. His holdings also included a pleasure garden in Copenhagen located outside the city's Northern City Gate. It was known as Prinsens Have and later Blågård, a name which is commemorated in several toponyms today.
Late years at Vemmetofte Manor
When Frederick IV had his wife by bigamy, Anne Sophie Reventlow, crowned as his queen, it led to a breach between the two brothers, and together with Princess Sophia Hedwig, his three years older sister, Prince Charles took up permanent residence at Vemmetofte Manor where they maintained an extravagant household. Von Plessen enjoyed such a reputation for exercising such a great influence on the prince that on one occasion it prompted the king to exclaim "Well there comes Prince Plessen with my brother Charles!" Ultimately, the two brothers were reconciled and in the end Prince Charles even ended up godfathering one of the king's children by Anne Sophie. After suffering from weak health throughout his life, Charles died in 1729 and was interred at Roskilde Cathedral.
