Prince Constantijn was born on 11 October 1969 at Utrecht University Hospital (now the University Medical Center Utrecht) in Utrecht following the births of his brothers, Willem-Alexander (b. 1967), and Johan Friso (1968–2013). He goes by the nickname Tijn. His godparents are former King Constantine II of Greece (1940–2023), Prince Aschwin of Lippe-Biesterfeld, Axel Freiherr von dem Bussche-Streithorst, Max Kohnstamm, and Corinne de Beaufort-Sickinghe.

Prince Constantijn studied law at Leiden University, becoming a lawyer, and then worked at the Brussels department of the (Dutch) European Union commissioner of foreign relations, Hans van den Broek. Later, he was hired by the EU and continued to work there in various capacities until the end of 1999. In December 2000, he was awarded a Master of Business Administration at INSEAD in Fontainebleau, France. He spent a summer working for the International Finance Corporation of the World Bank group in Washington, DC. He worked until late 2002 for strategic consultants Booz Allen Hamilton in London. Since 2003, he works for the RAND Corporation Europe in Brussels. Furthermore, he has a part-time position at the Netherlands Ministry of Foreign Affairs in The Hague.

Prince Constantijn rarely attends public events in his capacity as a member of the Dutch royal family. He is a keen sportsman and enjoys football, tennis, golf, and skiing. His other hobbies include drawing, cooking, and reading.

Marriage and family

The engagement of Prince Constantijn and Petra Laurentien Brinkhorst was announced on 16 December 2000. The civil marriage was conducted by the mayor of The Hague, Wim Deetman, in the Oude Raadzaal, Javastraat, The Hague, on 17 May 2001. The church wedding took place two days later on 19 May in the Grote of St Jacobskerk, with the Reverend Carel ter Linden officiating.

Prince Constantijn and Princess Laurentien have three children: Eloise (b. 2002), Claus-Casimir (b. 2004), and Leonore (b. 2006). The family then moved from Brussels, where they lived, to The Hague.

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 remain in the line of succession.
