Prince Carlos Xavier Bernardo Sixto Marie was born in Nijmegen, The Netherlands on 27 January 1970 as the elder child and son of Carlos Hugo, Duke of Parma, and his wife Princess Irene of the Netherlands.

He was baptized in the Catholic faith on 10 February 1970 by Archbishop Marcel Lefebvre, at that time in full communion with Rome.

He lived at the palace for a number of years with his grandparents, Queen Juliana of the Netherlands and Prince Bernhard of the Netherlands.

After completing his studies, Carlos worked for the company ABN AMRO in Amsterdam, where he was involved with preparations for the introduction of the euro.

He then worked for a period in Brussels as a public affairs consultant for the company European Public Policy Advisors (EPPA).

From 1996, he is also a member of the Dutch royal family with the style of "His Royal Highness" and the title of Prince Carlos de Bourbon de Parme.

Carlos is sometimes present at representative occasions concerning the Royal House of the Netherlands.

On 7 October 2009, it was announced through his mother's private secretary that Prince Carlos would marry Annemarie Cecilia Gualthérie van Weezel.

He is also considered as the legitimate King of Spain and Head of the Carlist Royal Family by the Carlists with the name of Don Carlos Javier, Rey de las Españas, since 2010, succeeding his father.

In Spain, he uses also the title of Duke of Madrid (Duque de Madrid).

The eldest son of Carlos Hugo, Duke of Parma and Princess Irene of the Netherlands, he is also titled as Prince de Bourbon in the French nobility.

He is the Grand Master of the Parmesan Sacred Military Constantinian Order of Saint George, the Order of Saint Louis for Civil Merit, the Order of Prohibited Legitimacy and the Order of St. George for Military Merit.

The civil marriage took place on 12 June 2010 at Wijk bij Duurstede.

The church wedding was to have taken place at the La Cambre Abbey in Ixelles on 28 August, but it was postponed owing to his father's illness.

In December 2015, the then 18-year-old Carlos Klynstra started the legal procedure to attempt to change his surname to that of his biological father which would also allow him to use the title of "Prince".

The Duke of Parma opposed this on the basis that it was in contravention of the traditions of the House of Bourbon-Parma.

On 9 March 2016 the Minister of Security and Justice declared his family name request valid.

Later that year a court in The Hague concurred with the minister in declaring the claim valid under Dutch law.

According to the judgement, Carlos Hugo will be entitled to be known as "Zijne Koninklijke Hoogheid Carlos Hugo Roderik Sybren prins de Bourbon de Parme" (His Royal Highness Prince Carlos Hugo Roderik Sybren of Bourbon-Parma); this will come only into effect once the Dutch king has signed the royal decree.

According to the press release of the Council of State of 28 February 2018, the name change does not mean that Klynstra is now also a member of the Royal House of Bourbon-Parma.

That is a private matter of the House itself and this is outside the jurisdiction of the Dutch Nobility Law.
