Crown Prince Christian of Denmark is suiting up for duty as he begins a new military training course.

On Aug. 14, the future king of Denmark, 19, was photographed participating in the Danish Armed Forces’ Lieutenant’s Training Course at Antvorskov Guard Hussar Barracks in Slagelse, Denmark, where he wore a camouflage uniform.

Crown Prince Christian is the eldest son of King Frederik and Queen Mary and his father’s future successor. It’s traditional across many of the royal houses of Europe for the heir to the throne to undertake military training, and Christian began his military service with the Guard Hussar Regiment in February.

A May statement from the Danish Royal House announced that the Crown Prince was officially a Guards Hussar and had been admitted to the Lieutenant’s Training Course, starting in August. The program lasts one year and is followed by a period of practical service as a platoon leader.

Before the Lieutenant’s Training Course began, the young royal had time off for some summer fun. Multiple outlets reported that Crown Prince Christian was spotted at Smukfest in Skanderborg on Aug. 8, appearing at the music festival that his sister, Princess Isabella, 18, also attended.

According to Music Festival Wizard, “Rock, heavy metal, pop, blues and folk fill the air of Denmark’s 2nd largest camping festival.” This year’s event featured performances by Will Smith, 50 Cent and Shawn Mendes.

King Frederik, 57, and Queen Mary, 53, are parents to Crown Prince Christian, Princess Isabella and twins Prince Vincent and Princess Josephine, 14, and their children’s lives are balanced out by royal duty and schooling.

Crown Prince Christian began his military training after graduating from Ordrup Gymnasium in June 2024 and embarking on an extended stay in East Africa, where he worked on a farm.

Christian’s farm stay was reminiscent of another royal’s similar trip, as Prince Harry worked on a farm in Australia after graduating from Eton in 2003 and before starting Sandhurst.

As Christian undertakes the next leg of his training, his siblings are also gearing up for a new school year.

On Aug. 11, the court gave an update on what the year ahead will look like for the King and Queen’s children, with Crown Prince Christian Christian continuing his military education and Princess Isabella and Princess Vincent returning to the schools they went to last year.

Princess Josephine, meanwhile, has a major change in store and will start at a boarding school about three hours’ away from her family’s home in Copenhagen.

“HRH Princess Josephine has chosen, at her own request, to continue her education in the 8th grade at Spir Efterskole,” the statement said about her surprise plans.

Princess Josephine is the youngest of King Frederik and Queen Mary’s four children and reportedly is the first of the bunch to go away to boarding school.
