Baudouin of Belgium in the context of "King Baudouin Stadium"

For most of its history, what is today Belgium was either a part of a larger territory, such as the medieval Carolingian Empire, or was divided into a number of smaller states. In the Middle Ages, the territory of present-day Belgium was fragmented into numerous feudal principalities, including the Duchy of Lower Lorraine, the Duchy of Brabant, the County of Flanders, the Prince-Bishopric of Liège, the County of Namur, the County of Hainaut and the County of Luxembourg. Belgium's modern shape can be traced back at least as far as the southern core of the medieval Burgundian Netherlands. The Eighty Years' War (1568–1648) later led to the split between a northern Dutch Republic and the Southern Netherlands from which Belgium and Luxembourg developed. The area, long a Habsburg stronghold, briefly came under Bourbon control during the War of the Spanish Succession. The resulting Peace of Utrecht transferred the area back to Habsburg control, creating what is now known as the Austrian Netherlands. The French Revolutionary wars led to Belgium becoming part of France in 1795. After the defeat of the French in 1814, the Congress of Vienna created two new states, the United Kingdom of the Netherlands and the Grand Duchy of Luxembourg, which were placed in dynastic union under the House of Orange-Nassau. The Southern Netherlands rebelled during the 1830 Belgian Revolution, establishing the modern Belgian state, officially recognized at the London Conference of 1830. The first King of Belgium, Leopold I, assumed the throne in 1831.

The first half of the twentieth century was tumultuous. Its historic neutrality was violated in each of the World Wars. During World War I, frustrated German invaders launched the Rape of Belgium. During the 1940 invasion, the quick surrender by Leopold III of Belgium to German forces drove a wedge between the King and his people. The King's attempt to return led to a constitutional crisis in 1950, which led to his abdication in favor of his son Baudouin. Belgium entered the second half of the twentieth century showing an unprecedented era of economic growth, as Belgium took an active role in the formation of the Benelux customs union with its neighbors. Ultimately, the Benelux union would serve as a model for the European Economic Community, a precursor to the European Union; to this day Brussels serves as the seat of many of the European Union institutions.

Princess Märtha of Sweden (Märtha Sofia Lovisa Dagmar Thyra; 28 March 1901 – 5 April 1954) was Crown Princess of Norway as the spouse of the future King Olav V from 1929 until her death in 1954. As Olav only became king in 1957, Märtha never became Queen of Norway. Her son, Harald V, is the current king of Norway. Princess Märtha was also an elder sister of Queen Astrid of Belgium and a maternal aunt of Grand Duchess Joséphine-Charlotte of Luxembourg and Kings Baudouin and Albert II of Belgium.

In 1940, Crown Princess Märtha and her family were immersed in World War II as Germany invaded Norway. After escaping to her home country of Sweden, and then being evacuated to America by President Franklin D. Roosevelt, she effectively advocated for Norway and did fundraising until the end of the war. In 1942, King Haakon VII of Norway, Märtha's father-in-law, invested her as a Dame Grand Cross of the Royal Norwegian Order of Saint Olav.

Leopold III (3 November 1901 – 25 September 1983) was King of the Belgians from 23 February 1934 until his abdication on 16 July 1951. At the outbreak of World War II, Leopold tried to maintain Belgian neutrality, but after the German invasion in May 1940, he surrendered his country, earning him much hostility, both at home and abroad.

Leopold's act was declared unconstitutional by Prime Minister Hubert Pierlot and his cabinet, who moved to London to form a government-in-exile, while Leopold and his family were placed under house arrest by the Germans. In 1944, they were moved to Germany and then Austria, before being liberated by the Americans, but banned for some years from returning to Belgium, where his brother Prince Charles, Count of Flanders, had been declared regent. Leopold's eventual return to his homeland in 1950 nearly caused a civil war, with serious calls for a secessionist republic in Wallonia. Under pressure from the government, he abdicated in favour of his son Baudouin in July 1951.

The royal question (French: question royale; Dutch: Koningskwestie) was a major political crisis in Belgium that lasted from 1945 to 1951, coming to a head between March and August 1950. The question at stake surrounded whether King Leopold III could return to Belgium and resume his constitutional role amid allegations that his actions during World War II had been contrary to the provisions of the Belgian Constitution. The crisis brought Belgium to the brink of a civil war. It was eventually resolved by the abdication of Leopold in favour of his son Prince Baudouin in 1951.

The crisis emerged from the division between Leopold and his Government, led by Prime Minister Hubert Pierlot, during the German invasion in May 1940. Leopold, who was suspected of authoritarian sympathies, had assumed command of the Belgian Army at the outbreak of war. Considering his constitutional position as commander-in-chief to take precedence over his civil role as head of state, he refused to leave his defeated troops and join the Belgian government in exile in France. Leopold's refusal to obey the Government marked a constitutional crisis and he was widely condemned after negotiating his army's surrender on 28 May 1940. He spent most of the occupation under house arrest in German-occupied Belgium. Shortly before the Allies liberated the country in 1944, Leopold was deported to Germany by the Nazis.

Princess Joséphine-Charlotte of Belgium (11 October 1927 – 10 January 2005) was the Grand Duchess of Luxembourg as the wife of Grand Duke Jean. She was the first child of King Leopold III of Belgium, and sister of the late King Baudouin and former King Albert II and aunt of King Philippe. She was also the maternal first cousin of King Harald V of Norway, maternal second cousin of former Queen Margrethe II of Denmark, and a paternal third cousin of late Queen Elizabeth II of the United Kingdom.

Albert II (born 6 June 1934) is a member of the Belgian royal family who reigned as King of the Belgians from 1993 until his abdication in 2013.

Albert II is the son of King Leopold III and the last living child of Queen Astrid, born a princess of Sweden. He is the younger brother of the late Grand Duchess Joséphine-Charlotte of Luxembourg and King Baudouin, whom he succeeded following Baudouin's death in 1993. He married Donna Paola Ruffo di Calabria (now Queen Paola), with whom he had three children. Albert's eldest son, Philippe, is the current King of the Belgians.

The Palace of the Nation (French: Palais de la Nation) is the official residence and principal workplace of the President of the Democratic Republic of the Congo. It is situated in Gombe, in the northern part of Kinshasa, next to the Congo River. It has held this role since 2001, following the assassination of Laurent-Désiré Kabila.

Constructed in 1956 based on Marcel Lambrichs [fr; nl]' design, the palais was initially conceived as the residence for the colonial Governor-General. After independence from Belgium, in 1960, the Palais metamorphosed into a symbol of the new state. The official proceedings commemorating the nation's newfound autonomy, including King Baudouin's Proclamation, declaring the Congo's independence and Patrice Lumumba's speech denouncing colonialism, took place in the palais on June 30. After the nation's independence, the residence briefly served as the seat of the Congolese parliamentary body, which now convenes in the People's Palace.

Elisabeth of Bavaria (Elisabeth Gabriele Valérie Marie; 25 July 1876 – 23 November 1965) was Queen of the Belgians from 23 December 1909 to 17 February 1934 as the wife of King Albert I, and a duchess in Bavaria by birth. She was the mother of King Leopold III of Belgium and of Queen Marie-José of Italy, and grandmother of kings Baudouin and Albert II of Belgium, the pretender Prince Vittorio of Italy as well as Grand Duchess Joséphine-Charlotte of Luxembourg
