Willem-Alexander of the Netherlands
King of the Netherlands (born 1967)

Willem-Alexander (Dutch: [ˈʋɪləm aːlɛkˈsɑndər]; Willem-Alexander Claus George Ferdinand; born 27 April 1967) is King of the Netherlands, reigning since 30 April 2013.
Willem-Alexander was born in Utrecht during the reign of his maternal grandmother, Queen Juliana, as the eldest child of Princess Beatrix (later Queen) and Prince Claus. He became Prince of Orange as heir apparent upon his mother's accession on 30 April 1980. He went to public primary and secondary schools in the Netherlands, and an international sixth-form college in Wales UWC Atlantic College. He served in the Royal Netherlands Navy, and studied history at Leiden University. He married Máxima Zorreguieta Cerruti in 2002, and they have three daughters: Catharina-Amalia, Alexia, and Ariane. Willem-Alexander succeeded his mother as monarch upon her abdication on 30 April 2013. He is the first man to hold this position since the death of his great-great-grandfather William III in 1890.
Willem-Alexander is interested in sports and international water management issues. Until his accession to the throne, he was a member of the International Olympic Committee (1998–2013), chairman of the Advisory Committee on Water to the Dutch Minister of Infrastructure and the Environment (2004–2013), and chairman of the Secretary-General of the United Nations' Advisory Board on Water and Sanitation (2006–2013).
This brief starts where responsible research should: with the source description of “Willem-Alexander of the Netherlands” as king of the Netherlands (born 1967). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as king of the Netherlands (born 1967). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q154952. VIAF identifies the subject as 78770708. The Library of Congress control number is n85152174. 5 of 5 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1967, 2013, 1980 and 2002.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
