The House of Glücksburg is the reigning royal house of Denmark and Norway and the former royal house of Greece, a branch of the ancient House of Oldenburg whose modern members all descend from King Christian IX of Denmark (1818 to 1906) and his wife Louise of Hesse-Kassel. Through the marriages of their six children, a minor ducal family from the Danish-German borderland became the common ancestor of monarchs in Copenhagen, Oslo and Athens, of a British queen consort, of a Russian empress, and of Prince Philip, Duke of Edinburgh. ## Origins The house takes its name from Glücksburg, a small castle town in Schleswig, and belongs to the Schleswig-Holstein-Sonderburg-Glücksburg line of the House of Oldenburg, which had held the Danish throne since 1448. Christian IX was a prince of that cadet branch with no expectation of ruling until the childless Frederik VII made the Danish succession an open European question. Christian succeeded him in 1863, and within months his second son was elected King of the Hellenes as George I, planting the family in Greece for 110 years. In 1905 his grandson Prince Carl of Denmark accepted the Norwegian throne as Haakon VII, giving Norway its own dynasty after centuries of union with Denmark and then Sweden. ## Notable members Christian IX was nicknamed the father-in-law of Europe: his daughter Alexandra married Edward VII of the United Kingdom, and his daughter Dagmar became Empress Maria Feodorovna of Russia, mother of Nicholas II. The Danish line runs through Christian X, Frederik IX and Queen Margrethe II, a trained archaeologist and illustrator who reigned from 1972 until her abdication in 2024, to her son King Frederik X and Queen Mary. The Norwegian line runs from Haakon VII and Queen Maud through Olav V, an Olympic sailing champion, to King Harald V and Crown Prince Haakon. The Greek line produced Constantine I, Paul, Constantine II and Queen Anne-Marie, Queen SofÃa of Spain, and Prince Andrew's son Philip, consort to Elizabeth II for 73 years. ## Significance No other western dynasty connects as many surviving monarchies in a single documented lineage. Two of Europe's ten reigning royal families, Denmark and Norway, are Glücksburg in the male line, and the house also sits in the ancestry of the British and Spanish royal families. Its history traces the transformation of European monarchy itself: from the dynastic matchmaking of the 1860s, through the loss of the Russian and Greek thrones, to the constitutional, publicly accountable monarchies of modern Scandinavia. | Fact | Details | | --- | --- | | House name | Schleswig-Holstein-Sonderburg-Glücksburg, a branch of the House of Oldenburg | | Founding figure of the modern house | Christian IX of Denmark (1818 to 1906) | | Ancestral seat | Glücksburg Castle, Schleswig | | Thrones held | Denmark (1863 to present), Greece (1863 to 1973), Norway (1905 to present) | | Current heads of state | Frederik X of Denmark, Harald V of Norway | | Best-known member abroad | Prince Philip, Duke of Edinburgh (1921 to 2021) | | Nickname of its founder | The father-in-law of Europe |
The Belgian royal family, formally the House of Belgium and dynastically a branch of the House of Saxe-Coburg and Gotha, is the reigning family of Belgium, founded when the German prince Leopold of Saxe-Coburg-Saalfeld accepted the throne of the newly independent kingdom in 1831 and continuing today through King Philippe and his heir, Princess Elisabeth, Duchess of Brabant. Belgium became independent from the Netherlands in 1830 and chose a constitutional monarchy. Its National Congress looked abroad for a sovereign who could balance French and British interests, and settled on Leopold, a widowed, well-connected and famously cautious prince who had already turned down the crown of Greece. He took the constitutional oath on 21 July 1831, still the Belgian national day. Seven monarchs have reigned since: Leopold I, Leopold II, Albert I, Leopold III, Baudouin, Albert II and Philippe. ## Origins The dynasty's roots are in the small Thuringian duchy of Saxe-Coburg, whose princes married into half the thrones of nineteenth-century Europe. Leopold I was the uncle of both Queen Victoria and her husband Prince Albert, and his second marriage, to Louise-Marie of Orleans, daughter of the French king Louis Philippe I, tied the new kingdom to Paris as well as London. The crown did not pass in a straight line: Leopold II's only son died at the age of nine, so the succession moved to Leopold II's brother Philippe, Count of Flanders, and then to Philippe's son, Albert I. Every Belgian monarch since 1909 descends from that collateral branch. ## Notable members Leopold II is the most studied and most criticised figure in the family, remembered for the industrial boom and monumental building of his reign and, above all, for his personal rule over the Congo Free State. Albert I and Queen Elisabeth of Bavaria became wartime symbols of Belgian resistance behind the Yser in 1914. Leopold III's surrender in 1940 and his conduct under occupation triggered the political crisis known as the Royal Question and ended in his abdication. Baudouin reigned for 42 years and presided over Congolese independence and Belgium's transformation into a federal state. Daughters of the house carried its blood outward: Charlotte became Empress Carlota of Mexico, Marie-Jose was the last Queen of Italy, and Josephine-Charlotte was Grand Duchess of Luxembourg. ## Significance In a country divided by language, the monarchy has been the one institution claimed by both Flemish and Walloon Belgians, and the king's role in brokering coalition governments remains politically real rather than ceremonial. The family has also changed with the country: equal succession was introduced in 1991, making Princess Elisabeth the first female Duchess of Brabant and the future first queen regnant of the Belgians, and in 2020 a court recognised Delphine of Saxe-Coburg as a daughter of Albert II. | Fact | Details | | --- | --- | | Dynasty | House of Belgium (Saxe-Coburg and Gotha) | | Country | Kingdom of Belgium | | Founder | Leopold I, King of the Belgians (1790-1865) | | Reigning since | 21 July 1831 | | Monarchs to date | Seven, from Leopold I to Philippe | | Current head | King Philippe (born 1960), reigning since 2013 | | Heir apparent | Princess Elisabeth, Duchess of Brabant (born 2001) | | Principal residences | Royal Palace of Brussels, Castle of Laeken | | Motto | L'union fait la force / Eendracht maakt macht |
The House of Stuart was the royal dynasty that ruled Scotland from 1371 and both Scotland and England from 1603 until 1714, giving Britain fourteen monarchs from Robert II to Queen Anne as well as the Jacobite claimants who carried its cause into exile. Spelled Stewart in Scotland and Stuart after Mary, Queen of Scots adopted the French form, the family holds the unusual distinction of having united two crowns by inheritance rather than conquest, and of ending in a disputed succession that reshaped the British constitution. ## Origins The family took its name from its office. The Stewarts were hereditary High Stewards of Scotland, a post granted in the twelfth century to a Breton house settled in Renfrewshire. In 1315 Walter Stewart, 6th High Steward, married Marjorie Bruce, daughter of King Robert the Bruce. Their son became Robert II in 1371 when the direct Bruce line failed, and the stewardship turned into a crown. For more than two centuries afterwards the Stewarts ruled Scotland alone, through a run of reigns cut short by battle, captivity and long royal minorities that left the nobility unusually powerful. ## Notable members James IV, the most cultivated of the Scottish kings, married Margaret Tudor in 1503 and so planted the claim that would carry his descendants to the English throne. His granddaughter Mary, Queen of Scots became queen at six days old, reigned briefly and turbulently, and was deposed in 1567 and executed in England twenty years later. Her son, James VI of Scotland, inherited the English crown in 1603 as James I and became the first monarch to rule both kingdoms. His son Charles I lost the Civil Wars and his throne; Charles II returned at the Restoration in 1660; James II and VII was deposed in the Revolution of 1688, after which his daughters Mary II and Anne reigned in his place. In exile his son James Francis Edward Stuart and grandson Charles Edward Stuart, remembered as Bonnie Prince Charlie, led the Jacobite attempts to recover the throne, ending with the rising of 1745. ## Significance No other British dynasty changed the shape of the state so much. The Stuarts brought Scotland and England under one sovereign, presided over the King James Bible and the theatre of Shakespeare's late career, lost a king to Parliament, and provoked the settlements of 1689 and 1701 that made the monarchy answerable to Parliament and Protestant by statute. When Queen Anne died childless in 1714, the crown passed under the Act of Settlement to the descendants of her cousin Sophia of Hanover, granddaughter of James VI and I, so every British monarch since is still a Stuart descendant. | Fact | Details | | --- | --- | | Founder | Robert II, King of Scots from 1371 | | Ruled | Scotland 1371 to 1714; England and Ireland 1603 to 1714 | | Origin | Renfrewshire, Scotland | | Union of the Crowns | 1603, under James VI of Scotland and I of England | | Last reigning monarch | Anne, Queen of Great Britain, died 1714 | | Jacobite claimants | James Francis Edward, Charles Edward and Henry Benedict Stuart | | Succeeded by | The House of Hanover, through Sophia of Hanover |
