Royal descendants of Queen Victoria and of King Christian IX

19th century edit

Victoria arranged the marriage of her eldest son and heir-apparent, the future Edward VII, to Alexandra of Denmark, the eldest daughter of Christian IX, which took place on 10 March 1863. Among their six children were George V (who was also Emperor of India throughout his reign) and his sister Maud of Wales (who would later marry their cousin Haakon VII of Norway, another grandchild of Christian IX, on 22 July 1896). However these two marriages were not the only unions among and between descendants of Victoria and Christian IX.^{[citation needed]}

The second son of Christian IX, Prince William, became King of Greece as George I shortly after his sister Alexandra's marriage due to this new connection with the British royal family. On 27 October 1889 his son, later Constantine I of Greece, married Sophia of Prussia, a granddaughter of Victoria, forging another union between descendants of the British queen and the Danish king.^{[citation needed]}

In 1865 Christian IX's second daughter, Princess Dagmar, became engaged to Tsarevich Nicholas of Russia, son and heir of Tsar Alexander II. Following the untimely death of her fiancé Dagmar married Nicholas's younger brother, the Tsarevich Alexander, in 1866, taking the Russian name Maria Feodorovna. Between 1881 and 1894 she was empress-consort of Russia. Her son, Nicholas II of Russia, married Alix of Hesse and by Rhine, yet another granddaughter of Queen Victoria, on 26 November 1894, and she became empress-consort as Alexandra Feodorovna.^{[citation needed]}

Other grandchildren became monarchs in their own right or consorts. Christian X of Denmark was the elder brother of Haakon VII of Norway and thus another grandson of Christian IX of Denmark. William II, German Emperor and King of Prussia, was the elder brother of Sophia of Prussia and thus another reigning grandson of Victoria. Lastly, Victoria had two more granddaughters who became queens: Marie of Edinburgh, who married Ferdinand I of Romania, and Victoria Eugenie of Battenberg, who married Alfonso XIII of Spain.^{[citation needed]}

Christian IX was therefore the grandfather of an emperor and two kings who all married granddaughters of Victoria, one of whom (Maud of Wales) was also a granddaughter of Christian IX. In total five of his grandsons were reigning sovereigns.^{[citation needed]}

Victoria, meanwhile, was the grandmother of an emperor, a king-emperor, four queens consort and an empress consort.^{[citation needed]}

First World War edit

During the First World War (1914–1918) many monarchs of countries from both sides were closely related owing to their descent from either Queen Victoria, Christian IX or both. The most commonly cited example is the fact that Constantine I of Greece and Nicholas II of Russia (through Christian IX), as well as Nicholas' wife, Alexandra Feodorovna, and Wilhelm II of Germany (through Victoria) were all first cousins of George V of the United Kingdom.^[1] Shortly before the end of the war, Nicholas, his wife and children were executed by the Bolsheviks.

Other countries who fought against Germany in addition to Russia and the United Kingdom were Romania, whose queen-consort, Marie, wife of Ferdinand I, was a cousin of Wilhelm II, and Greece, whose queen-consort, Sophia, wife of Constantine I, was Wilhelm II's sister.^{[citation needed]}

Other first cousins of George V, whose countries were neutral during the war, were Christian X of Denmark, Victoria Eugenie of Spain (queen-consort of Alfonso XIII) and Haakon VII of Norway (who was also George's brother-in-law via his marriage to George's sister, Maud).^{[citation needed]} Hugo Bates

Family tree of sovereign and consort grandchildren edit

The family tree below shows the relationships between the monarch grandchildren of Queen Victoria and King Christian IX.^{[citation needed]}

The unions between descendants of Queen Victoria and of King Christian IX did not end with the First World War, despite the overthrows of both the German and Russian monarchies (along with the House of Habsburg in Austria-Hungary). On the contrary, nearly all European reigning kings and queens today are most closely related through their descent from Victoria, Christian or both.

King Charles III of the United Kingdom, King Harald V of Norway, King Frederik X of Denmark and King Felipe VI of Spain are all descended from both Queen Victoria and King Christian IX.^[2] The first two monarchs are descendants of the aforementioned union between Alexandra of Denmark (daughter of King Christian IX) and Edward VII (son of Queen Victoria). Harald V of Norway is actually descended from Christian IX three ways, twice through his father and once through his mother. Frederik X of Denmark is descended once each from Victoria and Christian IX, through his mother, Queen Margrethe II. Felipe VI is descended from Victoria three ways and Christian IX twice. His father, King Juan Carlos I, is descended from Victoria and not Christian IX, while Juan Carlos' consort, Queen Sofía, is twice a descendant of Victoria and twice a great-great-granddaughter of Christian IX. Charles III is descended from both Christian IX and Queen Victoria twice, as his parents, Queen Elizabeth II and Prince Philip, were descendants of both monarchs.

King Carl XVI Gustaf of Sweden is descended from Victoria twice, his parents being second cousins because they were both great-grandchildren of Victoria. In addition Carl XVI Gustaf also descends on his maternal side from Victoria's half-sister Feodora. Carl XVI Gustaf is not a descendant of Christian IX; however he descends on his maternal side from the parents of Christian IX through Christian IX's elder brother, Friedrich.

Conversely, Philippe, King of the Belgians is descended from King Christian IX but not Queen Victoria, although he is a descendant of Victoria's maternal uncle (as well as her husband Prince Albert of Saxe-Coburg and Gotha's paternal uncle), Leopold I, King of the Belgians. Philippe's father, King Albert II, who abdicated in the summer of 2013, is a first cousin to Harald V of Norway through their grandfather Prince Carl, Duke of Västergötland, married to Princess Ingeborg of Denmark, a granddaughter of Christian IX.

To summarize:

• The Kings of Norway, Denmark, Spain and the United Kingdom are descended from both Victoria and Christian IX, with latter two having more than one line of descent from both.
• The King of Sweden is descended twice from Victoria (and from her half-sister) but not from Christian IX (although from one of his brothers).
• The King of the Belgians and the Grand Duke of Luxembourg are descended from Christian IX but not from Victoria, although they are descendants of Leopold I of the Belgians, uncle of both Victoria and Albert.
• The King of the Netherlands, Prince of Liechtenstein and Prince of Monaco are the three sovereigns of hereditary European monarchies descended from neither Victoria nor Christian IX.

Because so many monarchs descend from both Queen Victoria and King Christian IX of Denmark, the relationship between these two monarchs is of some interest. These monarchs were third cousins through their mutual descent from King George II of Great Britain. This relationship occurs twice because the maternal grandparents of King Christian IX of Denmark, Prince Charles of Hesse-Kassel (or Hesse-Cassel) (1744–1836) and Princess Louise of Denmark (1750–1831), were both children of daughters of King George II of Great Britain (1660–1727) and thus first cousins. Louise of Hesse-Kassel, wife of King Christian IX of Denmark, was a granddaughter of Prince Frederick of Hesse (1747–1837), the brother of the aforementioned Prince Charles of Hesse-Kassel.

Thus King Christian IX of Denmark and his wife Louise of Hesse-Kassel were both second and third cousins to each other and third cousins to Queen Victoria.
