Norway’s royal family has entered a new chapter following the death of King Harald V and the accession of his son, King Haakon VIII. The transition has also changed the positions held by Haakon’s two children, Crown Princess Ingrid Alexandra and Prince Sverre Magnus.
King Haakon and Queen Mette-Marit have two children together. Ingrid Alexandra, born in 2004, is their eldest, while Sverre Magnus arrived the following year. With Haakon now on the throne, Ingrid Alexandra is first in the line of succession and Sverre Magnus follows directly behind his sister.
There is also a third child in Queen Mette-Marit’s family. Marius Borg Høiby is her son from a relationship before she married Haakon. He grew up alongside the royal couple’s children but does not have a royal title and is not in the succession.
Here is a closer look at the new King of Norway’s children and their places in the monarchy.
Ingrid Alexandra
Crown Princess Ingrid Alexandra was born on January 21, 2004, at Rikshospitalet in Oslo. She is King Haakon and Queen Mette-Marit’s first child together.
Her position has always carried particular significance because Norway had already adopted absolute primogeniture before her birth. Under the modern succession system, an eldest child does not lose their place simply because a younger brother is born.
That meant Sverre Magnus’s arrival in 2005 did not change Ingrid Alexandra’s position.
For years, she stood second in line behind her father. Following Haakon’s accession in August 2026, she moved to first place and became the immediate heir to the Norwegian throne.
Future Queen
Ingrid Alexandra has been gradually prepared for the responsibilities that could eventually come with being Norway’s monarch.
Her upbringing has combined education and a relatively normal private life with increasing exposure to official royal duties. She has attended important national ceremonies and accompanied senior members of the Royal House at significant events.
Her 18th birthday in 2022 was an especially important royal milestone, with official celebrations bringing together members of European royal families.
Ingrid Alexandra has also completed military training. She served with the Engineer Battalion in Brigade North, giving her direct experience of Norway’s Armed Forces.
In 2025, she began studying social sciences at the University of Sydney in Australia.
Her education means she has not immediately become a full-time working royal simply because she is now heir to the throne. The transition gives her time to continue preparing for a constitutional role that could last for decades.
Sverre Magnus
Prince Sverre Magnus was born on December 3, 2005, in Oslo and is the younger child of Haakon and Mette-Marit.
With his father becoming King, Sverre Magnus moved up in the succession as well. He now follows his older sister, making him second in line to the Norwegian throne.
Although he occupies a prominent hereditary position, his future is expected to look different from Ingrid Alexandra’s.
She is being specifically prepared for the possibility of becoming sovereign. Sverre Magnus has greater freedom to build a life and career outside the core responsibilities reserved for the monarch and heir.
He nevertheless remains an important member of the King’s immediate family and has appeared at major royal celebrations and national occasions.
His Own Path
Sverre Magnus graduated from Elvebakken Upper Secondary School in Oslo in 2024.
As he entered adulthood, attention increasingly turned toward what kind of role he might choose for himself. He is not expected to carry the same full-time constitutional responsibilities as his sister.
In May 2025, the prince carried out his first independent official assignment when he attended an event honoring Norwegian athletes who had competed at the Special Olympics World Winter Games in Turin.
The engagement provided an early indication that he can represent the Royal House on selected occasions without necessarily following the same working-royal path as Ingrid Alexandra.
Marius Borg Høiby
Marius Borg Høiby is sometimes included when discussing Haakon and Mette-Marit’s family, but there is an important distinction.
Marius is Queen Mette-Marit’s eldest son from her previous relationship with Morten Borg. He was born on January 13, 1997, several years before Mette-Marit married then-Crown Prince Haakon in August 2001.
Haakon became his stepfather, and Marius grew up within the wider family alongside Ingrid Alexandra and Sverre Magnus.
However, he is not King Haakon’s biological son.
Marius has never held the title of prince, is not a member of the Royal House in the constitutional sense and has no position in Norway’s line of succession.
Harald’s Children
The new King’s family structure has an interesting similarity to that of his parents.
King Harald V and Queen Sonja also had two children: Princess Märtha Louise and Haakon.
Märtha Louise was born on September 22, 1971, making her almost two years older than her brother, who was born on July 20, 1973.
Despite being the firstborn, Märtha Louise did not become Harald’s heir.
At the time of their births, Norway’s succession system gave preference to male descendants. Haakon therefore stood ahead of his older sister.
Norway amended its Constitution in 1990 to establish equal succession for male and female descendants, but the change was not applied retroactively in a way that displaced Haakon.
A New Era
King Harald V’s death on August 28, 2026, ended a reign that had begun in January 1991.
His son’s accession immediately shifted the royal family into a new generation. Haakon went from heir to monarch, while Ingrid Alexandra assumed the position her father had occupied for most of his life.
It also means the three highest positions in the direct succession are now clearly defined: King Haakon VIII is the sovereign, Crown Princess Ingrid Alexandra is his heir, and Prince Sverre Magnus follows his sister.
Norway’s Royal Future
For those searching for the Norway King’s kids, King Haakon VIII has two biological children with Queen Mette-Marit: Crown Princess Ingrid Alexandra and Prince Sverre Magnus.
Their roles, however, are increasingly different.
Ingrid Alexandra is now directly in line to inherit the Crown and is being prepared for the responsibilities of a future sovereign. Sverre Magnus remains second in line but has considerably more flexibility to develop an independent career and public role.
Together, the siblings represent the generation that will carry Norway’s monarchy beyond the reigns of Harald V and Haakon VIII, with Ingrid Alexandra potentially becoming one of the most consequential Norwegian monarchs of the 21st century.
