Why did the Belgian King surrender to the Nazis while his government fled to London?
In short: Leopold III remained in Belgium to face the German occupation, a decision that triggered a constitutional crisis and branded him a traitor in the eyes of his own ministers. While his government operated from exile, the monarch's controversial choices during World War II nearly tore his country apart after the war.
When Germany invaded Belgium in May 1940, Leopold III took personal command of the army. As the situation deteriorated, he chose to surrender his forces on May 28, 1940, rather than follow his ministers into exile. This act caused an immediate rift; Prime Minister Hubert Pierlot and his cabinet declared the surrender unconstitutional, arguing that the King had acted without ministerial advice and had effectively abandoned his duty to the state. This created an "impossibilité de régner," or an inability to reign, as the government-in-exile in London refused to recognize his authority.
The King’s reputation suffered significantly during the war, exacerbated by his secret 1941 marriage to Lilian Baels, which violated Belgian law. His political standing was further damaged by his 1944 Political Testament, which adopted a hostile tone toward the Allies and failed to acknowledge the Belgian resistance. While he was held prisoner by the Germans until his liberation in 1945, his return to Belgium in 1950 sparked intense civil unrest, with strong opposition from Walloon, Liberal, and Socialist factions who viewed his wartime conduct as collaborationist.
The "royal question" regarding his future eventually forced a resolution. Although a 1950 plebiscite showed that nearly 58 percent of voters supported his return, the threat of civil war led him to transfer his royal powers to his son, Baudouin, in August 1950. He formally abdicated in July 1951. Despite his controversial legacy, some historians note that his capitulation was militarily inevitable, and his 1942 intervention with Hitler is credited with preventing the deportation of approximately 500,000 Belgian civilians to German munitions factories.
