Elisabeth currently attends school in Wales at the UWC Atlantic College and is expected to graduate in May 2020. She will one day be Belgium’s first queen regnant.
Prince Christian of Denmark:
He will one day ascend the throne after his father, Crown Prince Frederik. The 13-year-old is the eldest of Crown Prince Frederik and Crown Princess Mary’s four children. His three younger siblings are Princess Isabella, Prince Vincent and Princess Josephine. Born on 15 October 2005, he will turn 14 later this year.
Christian was the first member of the Danish Royal Family to attend a public school. He is enrolled at Tranegårdskolen with his three younger siblings.
Princess Amalia of the Netherlands:
Born Princess Catharina-Amalia, her title since her father’s ascension to the Dutch throne is the Princess of Orange. The eldest of King Willem-Alexander and Queen Máxima’s three daughters, she has gone by Amalia since birth. Her two younger siblings are Princesses Alexia and Ariane. Her father once joked that his three daughters “The A-Team” all had names beginning with an ‘a’ to keep their “triple-A rating.” She will celebrate her Sweet 16 in December.
She currently attends Christelijk Gymnasium Sorghvliet in The Hague.
Princess Ingrid Alexandra of Norway:
Born on 21 January 2004, Princess Ingrid Alexandra is the elder child and only daughter of Crown Prince Haakon and Crown Princess Mette-Marit of Norway. Her grandfather, King Harald is currently on the throne. She has one younger brother, Prince Sverre Magnus and one older half-brother from her mother’s previous relationship, Marius Borg Høiby.
The 15-year-old is attending the private Oslo International School where she undertakes courses in English to improve her skills in the language in preparation for her future role. She will be Norway’s second female monarch.
Princess Leonor of Spain:
Leonor, who as heir holds the title Princess of Asturias, is the elder daughter of King Felipe and Queen Letizia of Spain. Her younger sister is Infanta Sofía.
The 13-year-old is only heir presumptive to the Spanish throne because if her parents were to have a boy, she would be bumped down to second in line as Spain still operates under male-preference cognatic primogeniture.
Turning 14 on 31 October, Leonor will be Spain’s first queen regnant since the 1800s when Queen Isabella II was on the throne.
