Leopold III (born as Léopold Philippe Charles Albert Meinrad Hubertus Marie Miguel (French) or Leopold Filips Karel Albert Meinrad Hubertus Maria Miguel (Dutch) or Leopold Philipp Karl Albert Meinrad Hubertus Maria Miguel (German); 3 November 1901 – 25 September 1983) reigned as King of the Belgians from 1934 until 1951, when he abdicated in favour of the heir apparent, his son Baudouin.

Leopold III was born in Brussels as Prince Leopold of Belgium, Prince of Saxe-Coburg and Gotha, and succeeded to the throne of Belgium on 23 February 1934 following the death of his father, King Albert I.

He was invested as the 1,154th Knight of the Order of the Golden Fleece in Spain in 1923, the 355th Grand Cross of the Order of the Tower and Sword (Portugal) in 1927 and the 833rd Knight of the Order of the Garter (England) in 1935.

Prince Leopold, Duke of Brabant, fought as a private during World War I with the 12th Belgian Regiment while still a teenager, but was sent by his father to Eton College in the United Kingdom, in 1915. After the war, in 1919, the Duke enrolled at St. Anthony Seminary in Santa Barbara, California. He married Princess Astrid of Sweden in a civil ceremony in Stockholm on 4 November 1926, followed by a religious ceremony in Brussels on 10 November. The marriage produced three children:

  • Joséphine-Charlotte, Princess of Belgium, born at the Royal Palace of Brussels on 11 October 1927, Grand Duchess of Luxembourg. She was married on 9 April 1953 to Prince Jean, later Grand-Duke of Luxembourg. She died at Fischbach Castle on 10 January 2005.
  • Baudouin, Duke of Brabant, Count of Hainaut, Prince of Belgium, who became the fifth King of the Belgians as Baudouin, born at Stuyvenberg on the outskirts of Brussels on 7 September 1930, and died at Motril in Andalusia, Spain, on 31 July 1993.
  • Albert, Prince of Liège, Prince of Belgium, who became the sixth King of the Belgians as Albert II, born at Stuyvenberg on 6 June 1934. He abdicated in July 2013.

On 29 August 1935, while the King and Queen were driving along the winding, narrow roads near their villa at Küssnacht am Rigi, Schwyz, Switzerland on the shores of Lake Lucerne, Leopold lost control of the car which plunged into the lake, killing Queen Astrid.

Leopold married Lilian Baels on 11 September 1941 in a secret, religious ceremony, with no validity under Belgian law. They originally intended to wait until the end of the war for the civil marriage, but as the new Princesse de Réthy was soon expecting their first child, the ceremony took place on 6 December 1941. They had three children in total:

  • Alexander, Prince of Belgium, born in Brussels on 18 July 1942. In 1991, he married Lea Inga Dora Wohlman, a marriage revealed only seven years later. She was created a Princess of Belgium in her own right. He died on November 29, 2009.
  • Marie-Christine, Princess of Belgium, born in Brussels on 6 February 1951. Her first marriage, to Paul Drucker in 1981, lasted 40 days (though they were not formally divorced until 1985); she subsequently married Jean-Paul Gourges in 1989.
  • Maria-Esmeralda, Princess of Belgium, born in Brussels on 30 September 1956, a journalist, her professional name is Esmeralda de Réthy. She married Salvador Moncada, a noted pharmacologist, in 1998. They have a son and a daughter.

World War II

Royal Monogram

When World War II broke out in September 1939, the French and British governments immediately sought to persuade Belgium to join them. Leopold and his government refused, maintaining Belgium's neutrality. Belgium considered itself well-prepared against a possible invasion by Axis forces, for during the 1930s the Belgian government had made extensive preparations to deter and repel an invasion of the country, as in 1914, by an increasingly-belligerent Germany.

On 10 May 1940, the German Army invaded Belgium. On the first day of the offensive the principal Belgian strong point of Fort Eben-Emael was overwhelmed by a daring paratroop operation and the defensive perimeter thus penetrated before any French or British troops could arrive, and after a short running battle eventually involving the armies of all four belligerents, Belgium was overwhelmed by the numerically superior and better-prepared Germans.

Nevertheless, the Belgian perseverance prevented the British Expeditionary Force from being outflanked and cut off from the coast, enabling the evacuation from Dunkirk. After his military surrender, Leopold (unlike Queen Wilhelmina of the Netherlands, in a similar predicament) remained in Brussels to face the victorious invaders, while his entire civil government fled to Paris and later to London.

Surrender and constitutional crisis

On 24 May 1940, Leopold, having assumed command of the Belgian Army, met with his ministers for the final time. The ministers urged the King to leave the country with the Government. Prime Minister Hubert Pierlot reminded him that capitulation was a decision for the Belgian government, not the King. The King indicated that he had decided to remain in Belgium with his troops, whatever the outcome. The ministers took this to mean that he would establish a new government under the direction of Hitler, potentially a treasonous act. Leopold thought that he might be seen as a deserter if he were to leave the country: "Whatever happens, I have to share the same fate as my troops."[1] Leopold had long had a difficult and contentious relationship with his ministers, acting independently of government influence whenever possible, and seeking to circumvent and even limit the ministers' powers, while expanding his own.[1]

French, British, and Belgian troops were encircled by German forces at Dunkirk. Leopold notified King George VI by telegram on 25 May 1940 that Belgian forces were being crushed, saying "assistance which we give to the Allies will come to an end if our Army is surrounded".[2] Two days later (27 May 1940), Leopold surrendered the Belgian forces to the Germans.

Prime Minister Pierlot spoke on French radio, saying that the King's decision to surrender went against the Belgian Constitution. The decision, he said, was not only a military decision but also a political decision, and the King had acted without his ministers' advice, and therefore contrary to the Constitution. Pierlot and his Government believed this created an impossibilité de régner:

Should the King find himself unable to reign, the ministers, having observed this inability, immediately summon the Chambers. Regency and guardianship are to be provided by the united Chambers.[3]

It was impossible, however, to summon the Chambers at this time, and impossible to appoint a Regent. After the liberation of Belgium in September, 1944, the Government would ask Leopold's brother Prince Charles to serve as Regent.

After Leopold's surrender, the British press denounced him as "Traitor King" and "King Rat"; the Daily Mirror published a picture of Leopold with the headline "The Face That Every Woman Now Despises'". A group of Belgian refugees in Paris placed a message at King Albert's statue denouncing his son as "your unworthy successor".[4] French Prime Minister Paul Reynaud accused Leopold of treason. Flemish historians Valaers and Van Goethem wrote that Leopold III had become "The scapegoat of Reynaud"[5] because Reynaud was likely already aware that the Battle of France was lost.

Leopold's surrender was also decried by Winston Churchill: in the House of Commons on 4 June 1940 he said:

At the last moment when Belgium was already invaded, King Leopold called upon us to come to his aid, and even at the last moment we came. He and his brave, efficient Army, nearly half a million strong, guarded our left bank and thus kept open our only line of retreat to the sea. Suddenly, without prior consultation, with the least possible notice, without the advice of his ministers and upon his own personal act, he sent a plenipotentiary to the German Command, surrendered his Army and exposed our whole flank and means of retreat."[6]

In 1949, Churchill's comments about the events of May 1940 were published in Le Soir (12 February 1949). Leopold's former secretary sent a letter to Churchill saying that Churchill was wrong. Churchill sent a copy of this letter to the King's brother, the Regent Prince Charles, via his secretary André de Staercke. In his own letter Churchill wrote,

With regards to King Leopold, the words which I used at the time in the House of Commons are upon record and after careful consideration I do not see any reason to change them (...) it seemed to me and many others that the King should have been guided by the advice of his Ministers and should not have favoured a course which identified the capitulation of the Belgian Army with the submission of the Belgian State to Herr Hitler and consequently taking them out of the war. Happily this evil was averted, and in the end, all came right. I need scarcely say that nothing I said at the time could be interpreted as a reflection upon the personal courage or honour of King Leopold."[7]

De Staercke replied that Churchill was right: "The Prince, Monsieur Spaak and I read your text, which states the precise truth and seems perfect to us."[8]

André de Staercke was one of the most important witnesses to the Belgian government's internal crisis of 1940. At his request, his memoirs about Prince Charles (which he wrote at Churchill's suggestion) were only published after de Staercke's death in 2003, with the help of, and a preface by, Belgian historian Jean Stengers. The memoir underlines the fact that while King Baudouin of the Belgians generally did not like the people who opposed his father at the time of the Royal Question, de Staercke had become a friend of his. At the meal following the funeral of Prince Charles in June 1983, Baudouin placed de Staercke at his right.[9]

Belgian historian Francis Balace wrote that capitulation was inevitable because the Belgian Army was not able to fight any longer against the German army.[10] Even Churchill admitted that their position was perilous: in a telegram to Field Marshal Lord Gort on 27 May, only one day before the Belgian capitulation, he wrote, "We are asking them to sacrifice themselves for us."[11]

After the fall of France

Upon Leopold's surrender, the government ministers left for exile, mostly in France. When France fell at the end of June 1940, several ministers sought to return to Belgium. They made an overture to Leopold but were rebuffed:

Pierlot and his government saw that Western Europe had been conquered by the Germans completely and tried to make amends to their king. Would it be possible for them to return to Belgium and form a new government? Leopold showed his stubborn nature; he was insulted by his ministers... His reply was short: 'The situation of the King is unaltered; he does not engage in politics and does not receive politicians.' [1]

Because of the great popularity of the King, and the unpopularity of the civil government from the middle of 1940,[12] the government crisis persisted. The Royal Articles state:

This refusal [of the King to reconcile with the ministers] left the ministers with no other option than to move to London, where they could continue their work representing the independent Belgium. From the time of their arrival in London, they were confident about an Allied victory and soon were treated with respect by the Allies.... Pierlot and Spaak helped to build Leopold's reputation as a heroic prisoner of war and even said that the Belgians should support their King. But they had no idea what Leopold was doing in [the Royal Palace at] Laeken. He refused to reply to their messages and stayed cool toward them. What was he doing in the castle? Was he collaborating, did he oppose the Germans, or had he decided to just shut his mouth and wait to see how things would go?[1]

On 2 August 1940, several ministers conferred in Le Perthus, in France near the Spanish border. Prime Minister Pierlot and Foreign Minister Paul-Henri Spaak were persuaded to go to London; but they were able to start only at the end of August, and could travel only via neutral Spain and Portugal. When they reached Spain, they were arrested and detained by the Franco regime; they arrived finally in London on 22 October.

Meeting with Hitler

Leopold rejected cooperation with the Nazis and refused to administer Belgium in accordance with their dictates, and the Germans implemented a military government. Leopold attempted to assert his authority as monarch and head of the Belgian government although he was a prisoner of the Germans. Despite his defiance of the Germans, the Belgian government-in-exile in London maintained that the King did not represent the Belgian government and was unable to reign. The Germans held him at first under house arrest at the Royal Palace of Laeken in Brussels. Having desired a meeting with Adolf Hitler since June 1940, Leopold III finally met with him on 19 November 1940. Leopold wanted Hitler to issue a public statement about Belgium's future independence. Hitler's vision of a united Europe did not include independent countries within its borders.[citation needed] Hitler refused to speak about the independence of Belgium or issue a statement about it. In refusing to publish a statement, Hitler unintentionally preserved the King from being seen as cooperating with Germany, and thus engaged in treasonous acts, which would likely have obliged him to abdicate upon liberation of Belgium. "The [German] Chancellor saved the King two times."[13]

Second marriage

On 11 September 1941, while a prisoner of the Germans, Leopold secretly married Lilian Baels in a religious ceremony that had no validity under Belgian law, as Belgian law required a religious marriage to be preceded by a legal or civil marriage. On 6 December, they were married under civil law. The reason for the out-of-order marriages was not made public, but they had a child seven months later, in June 1942. It would have been unacceptable for a King of the Belgians to have maintained an "unofficial" relationship with Lilian.

Dr Jozef-Ernest Cardinal van Roey, Archbishop of Mechelen, wrote an open letter to parish priests throughout the country announcing Leopold's second marriage on December 7. The letter from the Cardinal revealed that the King's new wife would be known as Princesse de Réthy, not Queen Lilian, and that any children they had would have no claim to the throne (though they would be Princes or Princesses of Belgium with the style Royal Highness). Leopold's new marriage damaged his reputation further in the eyes of many of his subjects.

The Political Testament

The ministers made several efforts during the war to work out a suitable agreement with Leopold III. They sent Pierlot's son-in-law as an emissary to Leopold in January 1944, carrying a letter offering reconciliation from the Belgian government in exile. The letter never reached its destination, however, as the son-in-law was killed by the Germans en route. The ministers did not know what happened to either message or messenger, and assumed Leopold was ignoring them.

Leopold wrote his Political Testament in January 1944 shortly after this failed attempt at reconciliation. The testament was to be published in case he was not in Belgium when Allied forces arrived. The testament, which had an imperious and negative tone, considered the potential Allied movement into Belgium an "occupation", not a "liberation". It gave no credit to the active Belgian resistance. The Belgian government in London did not like Leopold's demand that the government ministers involved in the 1940 crisis be exonerated. The Allies did not like Leopold's repudiation of the treaties concluded by the Belgian government-in-exile in London. The United States was particularly concerned about the economic treaty it had reached with the Belgian government in London that enabled them to obtain Congolese uranium for America's secret atom bomb program.

The Belgian government did not publish the Political Testament and tried to ignore it, partly for fear of increased support for the Belgian Communist party. When Pierlot and Spaak learned of its contents in September 1944, they were astonished and felt deceived by the king. According to André de Staercke, the Regent's Secretary, they were dismayed "in the face of so much blindness and awareness".[14]

Churchill's reaction to the Testament: "It stinks."[15] In a sentence inspired by a quote of Talleyrand about the Bourbons after the restoration of the French monarchy in 1815, Churchill declared: "He is like the Bourbons, he has learned nothing and forgotten everything."[16]

Exile and abdication

Deportation and exile

In 1944, Heinrich Himmler ordered Leopold deported to Germany. Princess Liliane followed with the family in another car the following day under an SS armed guard. The Nazis held the family in a fort at Hirschstein in Saxony from June 1944 to March 1945, and then at Strobl, Austria.

The British and American governments worried about the return of the king. Charles W. Sawyer, US Ambassador to Belgium, warned his government that an immediate return by the king to Belgium would "precipitate serious difficulties". "There are deep differences even in the Royal family and the situation holds dynamite for Belgium and perhaps for Europe".[17] "The Foreign Office feared that an increasing minority in French-speaking Wallonia would demand either autonomy or annexation to France. Winant, the American Ambassador to the Court of Saint James's, reported a Foreign Office official's concern regarding irredentist propaganda in Wallonia."[18] and that "the French Ambassador in Brussels... is believed to have connived in the spreading of this propaganda".[19]

Leopold and his companions were freed by members of the United States 106th Cavalry Group in early May 1945. Because of the controversy about his conduct during the war, Leopold III and his wife and children were unable to return to Belgium and spent the next six years in exile at Pregny-Chambésy near Geneva, Switzerland. A regency under his brother Prince Charles had been established by the Legislature in 1944.

Resistance to Leopold's return

Van den Dungen, the rector of the Université Libre de Bruxelles wrote to Leopold on 25 June 1945 about concerns for serious disorder in Wallonia, "The question is not if the accusations against you are right or not [but that...] You are no more a symbol of the Belgian unity."[20]

Gillon, the President of the Belgian Senate, told the king that there was a threat of serious disorder: "If there are only ten or twenty people killed, the situation would become terrible for the King.".[21]

The President of the Belgian Chamber of Representatives, Frans Van Cauwelaert, was concerned that there would be a General strike in Wallonia and revolt in Liège. He wrote, "The country is not able to put down the disorders because of the insufficient forces of the police and a lack of weapons."[22]

In 1946, a commission of inquiry exonerated Leopold of treason. Nonetheless, controversy concerning his loyalty continued, and in 1950, a referendum was held about his future. Fifty-seven per cent of the voters favoured his return. The divide between Leopoldists and anti-Leopoldists ran along the lines of socialists and Walloons who were mostly opposed (42% favourable votes in Wallonia) and Christian Democrats and Flemings who were more in favour of the King (70% favourable votes in Flanders).

General strike of 1950

On 31 July 1950, after the fusillade of Grâce-Berleur, Liège and other municipalities of Wallonia replaced the Belgian flag with the Walloon flag

On his return to Belgium in 1950, Leopold was met with one of the most violent general strikes in the history of Belgium. Three protesters were killed when the gendarmerie opened automatic fire upon the protesters. The country stood on the brink of civil war, and Belgian banners were replaced by Walloon flags in Liège and other municipalities of Wallonia.[23] To avoid tearing the country apart, and to preserve the monarchy, Leopold decided on 1 August 1950 to withdraw in favour of his 20-year-old son Baudouin. His abdication took effect on 16 July 1951, though in reality the government had already forced the issue on 1 August 1950. In this postponed abdication[24] the king was, in effect, forced by the government of Jean Duvieusart to offer to abdicate in favour of his son.[25]

Post abdication life

Leopold and his wife continued to advise King Baudouin until the latter's marriage in 1960. Some Belgian historians, such as Vincent Delcorps, speak of there having been a "dyarchy" during this period.[26]

In retirement, he followed his passion as an amateur social anthropologist and entomologist and travelled the world. He went, for instance, to Senegal and strongly criticized the French decolonization process, and he explored the Orinoco and the Amazon with Heinrich Harrer.[27]

Leopold died in 1983 at Woluwe-Saint-Lambert (Sint-Lambrechts-Woluwe). He is interred next to Queen Astrid (and also later his second wife, The Princess de Réthy was interred with them) in the royal vault at the Church of Our Lady of Laeken.
