Norway's Princess Ingrid Alexandra, 22, poised to be first queen in 600 years

Crown Princess Ingrid Alexandra, 22, has taken on a historic role as Norway's heir to the throne following King Haakon's accession. With Haakon's constitutional oath now taken, Ingrid Alexandra becomes the first adult heir at the time of succession in the country's modern history. Should she eventually ascend to the throne, she would become Norway's first reigning queen in more than six centuries. Her position marks a significant moment in the Scandinavian nation's royal history.
