Why Belgium’s monarch is the King of the Belgians, not the King of Belgium

In short: Belgium’s monarchy is a unique constitutional experiment where the sovereign is not a ruler of territory, but a symbolic bond to the people. Unlike other European crowns, the King has no physical crown and must swear a constitutional oath to take the throne, acting as a guardian of national unity.

The Belgian monarchy was established in 1830, simultaneously with the country's independence from the United Kingdom of the Netherlands. Because the state, its parliamentary system, and the monarchy were created at once, the limits of royal power were never defined with absolute precision. This has led to an ongoing debate about whether the King is merely a symbolic figurehead or an active participant in state affairs. While the constitution vests federal executive power in the monarch, Article 106 requires that every royal act be countersigned by a minister, who then assumes full political responsibility. In practice, this means the King reigns but does not rule, though he retains the right to be informed, to advise, and to warn during weekly meetings with the Prime Minister.

The title King of the Belgians, rather than King of Belgium, reflects a concept of popular monarchy. This terminology emphasizes a personal connection to the citizenry rather than ownership of the land. The office is hereditary, restricted to descendants of Leopold I, the first King. Accession is not automatic; the heir must swear a constitutional oath before a joint session of Parliament within ten days of the previous monarch's death or abdication. This oath, delivered in French, Dutch, and German, underscores the monarch's role as a unifying force across the country's linguistic divides.

The institution has navigated significant historical shifts, including the controversial colonial legacy of Leopold II in the Congo Free State and the anti-German sentiment of the First World War, which prompted the royal family to change their name from Saxe-Coburg-Gotha to the Belgian-language variants of 'of Belgium' in 1920. While the family removed the Saxon coat of arms during the war, King Philippe reinstated the Saxonian escutcheon in 2019 following a visit to the ancestral Friedenstein Castle. Today, the monarch remains a central, if complex, piece on the Belgian political chessboard, serving as the Commander-in-Chief of the Armed Forces and a final signatory for all federal laws.
