Secret Succession Pact Between Belgian Kings Baudouin and Albert II Revealed
A newly revealed secret agreement between King Baudouin of Belgium and his younger brother Prince Albert — later King Albert II — has shed unprecedented light on contingency planning within the Belgian royal family, showing that Baudouin had meticulously prepared for his own premature death to ensure his nephew Philippe would have time to marry and start a family before taking the throne.
The revelation comes from historian Vincent Dujardin’s landmark 900-page biography, “Baudouin, un roi face aux crises de son temps” (“Baudouin, A King Facing the Crises of His Time”), published by Mame in French and Lannoo in Dutch. Dujardin, a professor at UCLouvain, spent nearly 20 years researching the work and gained unprecedented access to Baudouin’s private diaries, personal notebooks, and spiritual journals — a first for any historian.
The Secret Agreement
According to La Libre Belgique, which first reported the story on 16 May 2026, the agreement stipulated that under normal circumstances, Baudouin intended for his nephew Prince Philippe — Albert’s eldest son and the current King Philippe — to succeed him directly. However, if Baudouin died before Philippe married and had children, Albert would ascend the throne first, giving Philippe time to find a spouse and start a family.
This contingency plan was not merely theoretical. It was nearly activated in April 1990, when Baudouin faced a profound constitutional crisis over the abortion law. The deeply Catholic king refused to sign legislation decriminalizing abortion, citing a “conflict of conscience.” The government ultimately declared Baudouin “unable to reign” for 48 hours under Article 82 of the Constitution, allowing the council of ministers to sign the law before reinstating him.
Albert II’s Confession
Albert II himself confirmed the arrangement to Dujardin on 26 January 2026. As RTBF reported, the former king recounted arriving at Motril, the Spanish villa where Baudouin had died, and being led by Queen Fabiola to see his brother. “The smiling face of Baudouin struck me,” Albert recalled. “After consulting the Queen, I confirmed to Dehaene that I accepted to succeed Baudouin. I added that I had the impression that I would be the last King of the Belgians.”
Dujardin’s Research Breakthrough
Dujardin’s biography represents a watershed moment in Belgian royal historiography. As VRT NWS noted, the historian had access to Baudouin’s private diaries — a first — along with his political agendas and spiritual notebooks. “The intimate diaries of Baudouin show that the King informed Prince Philippe before even Prince Albert,” Dujardin told VRT, “but also that if he had had to abdicate because of the crisis, he would have asked his brother to succeed him, in order to leave Philippe time to find his soulmate.”
The 1990 Abortion Crisis Context
The secret succession plan was intimately tied to the abortion crisis. According to DHNet, Baudouin’s diaries reveal he had been wrestling with the issue since at least 1982. In one entry from 22 January 1990, he wrote: “Jesus, you must help me. Do not let me undertake anything that is not willed by you.” The diaries show he consulted Pope John Paul II and Cardinal Ratzinger (the future Pope Benedict XVI) before ultimately deciding alone that he would not sign the law.
What Happened in 1993
When Baudouin died of a heart attack on 31 July 1993 at his vacation residence in Motril, southern Spain, at age 62, Prince Philippe was 33 and unmarried. The secret agreement was activated: Albert II became the 6th King of the Belgians on 9 August 1993 and reigned until his abdication on 21 July 2013, at which point Philippe — by then married to Queen Mathilde with four children — finally succeeded him.
Historical Significance
The revelation fills a long-standing gap in understanding the 1993 succession. For decades, observers questioned why Albert II became king instead of Philippe, who had been groomed for the role. The agreement shows Baudouin himself anticipated this scenario with a deliberate plan to ensure dynastic stability.
Dujardin’s biography also addresses other major aspects of Baudouin’s reign, including his role in Congo’s independence, the Lumumba assassination controversy, and his relationship with General Franco. As the historian told RTBF: “This is a biography that allows us to better know who the man behind the King was, in addition to bringing new insights concerning the royal function itself.”
What’s Next
The revelation raises intriguing questions about whether other secret agreements within the Belgian royal family may yet come to light. Dujardin’s unprecedented access to Baudouin’s private archives has already transformed understanding of one of Belgium’s most consequential reigns, and historians will likely continue to mine the 900-page biography for further insights into the monarchy’s inner workings.
