The Youngest Royal Heirs and Heiresses in Line for the Throne
We're all familiar with the children of the British royal family—Prince George, Princess Charlotte, Prince Louis and even Archie Harrison, who is further down the line to the crown. But what about the young heirs and heiresses of monarchies in other parts of the world? We round up the youngest royals around the globe, who are set to become the monarchs of tomorrow.
1/13 Prince Charles of Luxembourg
Born on May 10, 2020, the royal baby of Prince Guilliame and Princess Stéphanie is already second in line to the throne of Luxembourg, a small European country bordered by Belgium, France and Germany.
The young prince made his public appearance for the first time on the steps of Grand Duchess Charlotte Maternity Hospital two days after he was born, and met his grandparents, the Grand Duke Henri and Grand Duchess Maria Teresa of Luxembourg via a video call.
2/13 Prince Jigme Namgyel Wangchuck of Bhutan
The heir apparent to the throne of Bhutan, Crown Prince Jigme Namgyel Wangchuck is the first child of King Jigme Khesar Namgyel Wangchuck of Bhutan and his wife, Queen Ashi Jetsun Puma—who is the world’s youngest living queen.
The four-year-old is also known as the Dragon Prince, and his birth in 2016 was celebrated with the planting of 108,000 trees.
3/13 Prince Jacques of Monaco
Born in 2014, two minutes after his twin sister Princess Gabriella, Prince Jacques is the hereditary heir of Monaco, where male heirs take precedence. The five-year-old son of sovereign Prince Albert II and Princess Charlene also holds the title of Marquis de Baux, which is traditionally given to all heir apparent to the Monegasque throne.
The birth of the twins was marked with forty-two cannon shots from the Fort Antoine. Church bells rang for 15 min, followed by boat horns. When the prince and princess were presented on January 7, 2015, it was declared a public holiday in Monaco.
4/13 Prince Taufa'ahau Manumataongo of Tonga
Prince Taufa'ahau Manumataongo, who recently turned seven, is second in line to the throne of Tonga after his father Crown Prince Tupoutoʻa ʻUlukalala. Tonga is the last Polynesian kingdom in the South Pacific, and was a protectorate of the United Kingdom between 1900 to 1970.

5/13 Princess Estelle of Sweden
Eight-year-old Princess Estelle is the eldest child of Crown Princess Victoria and her husband, Prince Daniel, second-in-line to the Swedish throne. Also holding the title of Duchess of Östergötland, Estelle’s birth was celebrated with much fanfare as she was the first female royal to be born with the right to inherit the throne as heir apparent.
This is because Sweden adopted absolute primogeniture in 1980, which allowed for the eldest child to be first in the line of succession regardless of gender. Her birthday was marked by two 21-gun salutes on Skeppsholmen island, opposite the Royal Palace in Stockholm.
6/13 Prince Hisahito of Akishino
The nephew of Emperor Naruhito, 13-year-old Prince Hisahito is the youngest and only son of Crown Prince Akishino, and second in line to the Chrysanthemum Throne.
His older sister is Princess Mako, who famously announced in 2017 that she was giving up her royal status to marry a commoner. There has been a lot of uncertainty surrounding her marriage, which has been indefinitely postponed for two years.
7/13 Princess Leonor of Asturias
The eldest of Spain’s King Felipe VI and Queen Letizia’s two daughters, 14-year-old Princess Leonor is the heir presumptive to the throne, and is set to become the first reigning Spanish queen since 1868—should her father not produce a male heir during his reign. Leonor began taking on royal duties in 2018, at the age of 12.
She has made various public speeches since, and recently read a passage from Don Quixote with her sister Princess Sofia via video, paying tribute to frontliners of the Covid-19 pandemic.
8/13 Prince Christian of Denmark
The eldest child of Crown Prince Frederik and Crown Princess Mary, 14-year-old Prince Christian is second in line to the throne of Denmark. The prince’s birth was celebrated with 21-gun salutes, which were fired from the Sixtus Battery at Holmen, Copenhagen and Kronborg Castle.
Public buses and buildings flew the Danish flag, while beacon bonfires were lit in Denmark as well as Australia. He was granted the title of Count of Monpezat in 2008 by Queen Margethe.
9/13 Prince Dipangkorn Rasmijoti, Thailand
Despite being the youngest of King Maha Vajiralongkorn’s five sons, Prince Dipangkorn is the only recognised heir to the throne, from the monarch’s marriage with his third wife, Srirasmi Suwadee.
The relationship ended in divorce in 2014—in part to allegations of corruption towards the former royal consort’s family—leaving Dipangkorn in the king’s care. The 15-year-old prince is currently studying in Munich, Germany.

10/13 Prince Hashem bin Abdullah of Jordan
The youngest child of King Abdullah II and Queen Rania Al Abdullah, 15-year-old Prince Hashem is second in line to the throne, after his older brother 25-year-old Crown Prince Al Hussein bin Abdullah II.
That is likely to change, however, if Al Hussein produces a male heir after marriage. The brothers share a close relationship and the young prince is often photographed alongside Al Hussein on official duties.
11/13 Princess Catharina-Amalia of the Netherlands
16-year-old Princess Catharina-Amalia is the oldest child of King Willem-Alexander and Queen Máxima. As the heir apparent to the throne, she holds the title of Princess of Orange, as well as Princess of the Netherlands and Princess of Orange-Nassau.
She will also assume a seat in the Advisory Division of the Council of State of the Netherlands when she turns 18. The princess’s hobbies include horse riding, field hockey, singing and playing the piano.
12/13 Princess Ingrid Alexandra of Norway
The daughter of Crown Princess Mette-Marit and Crown Prince Haakon, 16-year-old Princess Ingrid Alexandra is second in line to the throne of Norway and is set to become its second female monarch since the 15th century. The princess confirmed her faith to the Lutheran church in a grand ceremony last year, which was celebrated with the gift of a nature reserve from the Norwegian government.
The teenage royal counts paternal grandfather King Harald V of Norway, maternal grandmother Marit Tjessem, her aunt Princess Märtha Louise of Norway, as well as King Felipe VI of Spain; Frederik, Crown Prince of Denmark; and Victoria, Crown Princess of Sweden amongst her godparents.
13/13 Prince Moulay El Hassan of Morocco
The first child of King Mohammed VI and Princess Lalla Salma, 17-year-old Prince Moulay El Hassan is the heir apparent to the crown of Morocco. The prince began appearing at official engagements with his father in 2015 and is passionate about his diplomatic duties.
He was the youngest participant at the One Planet Summit in France in 2017 and is also reportedly interested in studying aviation. He owns a Gulfstream G650 jet, which he travels in. The net worth of his family is estimated to be US$5.7 billion.
