Count Claus-Casimir of Orange-Nassau, Jonkheer van Amsberg (Claus-Casimir Bernhard Marius Max; born 21 March 2004), is the second child of Prince Constantijn and Princess Laurentien of the Netherlands [1] and their only son. He is a member of the Dutch royal family and is sixth in the line of succession to the Dutch throne. [2] He bears the style "His Highness" and the title of Count of Oranje-Nassau (with princely rank).
His birth was overshadowed by the death, only a day before, of his great-grandmother Queen Juliana. [3] He has two sisters: Countess Eloise, born 8 June 2002 and Countess Leonore, born 3 June 2006.
His baptism took place in the chapel of Het Loo Palace in Apeldoorn on 10 October 2004. [4] Claus-Casimir's godparents are King Willem-Alexander, Prince Maurits of Orange-Nassau, van Vollenhoven, Ed P. Spanjaard, and Countess Tatiana Razumovsky von Wigstein.
Claus-Casimir grew up in Brussels before moving to The Hague in 2016. After attending high school at Vrijzinnig Christelijk Lyceum (VCL) in The Hague, Claus-Casimir moved to Scotland in 2020 to attend Gordonstoun School, leaving in 2022. From September 2022 until June 2025, he studied at ESCP Business School.[ citation needed ]
By royal decree of 11 May 2001, nr. 227, it was determined that all children and male-line descendants of Prince Constantijn of the Netherlands would bear the title of Count (ess) of Orange-Nassau (with princely rank) and the honorific Jonkheer (Jonkvrouwe) van Amsberg with the style of "His/Her Highness" and have the surname Van Oranje-Nassau van Amsberg.
Upon the abdication of Queen Beatrix on 30 April 2013, the children of Prince Constantijn and Princess Laurentien ceased to be members of the Royal House, although they continue to be members of the royal family and in the line of succession to the Dutch throne. [5]
