Royal descendants of Queen Victoria and King Christian IX
The royal descendants of Queen Victoria (Queen of the United Kingdom) and of Christian IX (King of Denmark) currently occupy the thrones of Belgium, Denmark, Norway, Spain, Sweden and the United Kingdom. At the outbreak of the First World War their grandchildren occupied the thrones of Denmark, Greece, Norway, Germany, Romania, Russia, Spain and the United Kingdom. For this, Queen Victoria was nicknamed "the grandmother of Europe" while Christian IX was nicknamed "Father-in-law of Europe". Of the remaining kingdoms of Europe today, only Willem-Alexander of the Netherlands descends neither from Queen Victoria nor Christian IX.
Queen Victoria arranged the marriage of her eldest son and heir-apparent, the future Edward VII to Alexandra of Denmark, the eldest daughter of King Christian IX, which took place on March 10, 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 King Haakon VII of Norway, another grandchild of Christian IX, on July 22, 1896). However, these two marriages were not the only unions amongst and between descendants of Victoria and Christian IX.
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 October 27, 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.
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 fiancee, 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 November 26, 1894, and she became empress-consort as Alexandra Feodorovna.
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 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.
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.
Victoria, meanwhile, was the grandmother of an emperor, a king-emperor, four queens consort and an empress consort.
First World War
During the First World War (1914–1918), many monarchs of countries from both sides were closely related due to their mutual descent from either Queen Victoria, King Christian IX or both. The most commonly cited example is the fact that King George V of Great Britain, Kaiser Wilhelm II of Germany and Empress Alexandra Feodorovna of Russia, empress consort of Tsar Nicholas II, were all first cousins via Queen Victoria. Other relatives who fought against Germany in addition to Russia and the United Kingdom were Romania, whose queen-consort, Marie, wife of King Ferdinand I, was a cousin of the Kaiser and Greece, whose queen-consort, Sophia, wife of King Constantine I, was the Kaiser's own sister. Additionally, King George V was a first cousin, through King Christian IX, of both Tsar Nicholas II of Russia and King Constantine I of Greece. Shortly before the end of the war, Nicholas, his wife and children were executed by the Bolsheviks. Other first cousins of George V, whose countries were neutral during the war, were King Christian X of Denmark, Queen Victoria Eugenie of Spain (queen-consort of King Alfonso XIII) and King Haakon VII of Norway (who was also George's brother-in-law via his marriage to George's sister, Maud).

Present-day reigning descendants
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 House of Hapsburg 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.
Presently, there are seven kingdoms remaining in Europe:
1. Belgium: Philippe & Queen Mathilda
2. Denmark: Margrethe II & Prince Consort Henrik
3. Norway: Harald V & Queen Sonja
4. Spain: Juan Carlos I & Queen Sofía
5. Sweden: Carl XVI Gustaf & Queen Silvia
6. United Kingdom: Elizabeth II & The Duke of Edinburgh
7. Netherlands: Willem-Alexander & Queen Máxima
King Harald V of Norway, Queen Elizabeth II of the United Kingdom, her husband, the Duke of Edinburgh, Queen Margrethe II of Denmark and Queen Sofía of Spain are all descended from both Queen Victoria and King Christian IX. The first two monarchs are great-grandchildren of the aforementioned union between Alexandra of Denmark (daughter of 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. Prince Philip, Duke of Edinburgh and his wife Elizabeth II are second cousins once removed through Christian IX and also third cousins as they are both great-great-grandchildren of Queen Victoria. Queen Sofía of Spain is twice a descendant of Queen Victoria and twice a great-great-granddaughter of Christian IX. Margrethe II of Denmark is descended once each from Queen Victoria and Christian IX. She is also a first cousin to Carl XVI Gustaf of Sweden through Victoria's granddaughter Princess Margaret of Connaught.
The husband of Queen Sofía, Juan Carlos I of Spain, is descended from Queen Victoria and not from Christian IX. Thus, the couple's closest relationship is of third cousins. King Carl XVI Gustaf of Sweden is also descended from Queen Victoria and not Christian IX, but he is her descendant twice, as his parents were second cousins because they were both great-grandchildren of Victoria. (Carl XVI Gustaf of Sweden is however descended from the parents of Christian IX through Christian IX's brother Friedrich.)
Conversely, King Philippe of Belgium is descended from Christian IX but not Queen Victoria, although, he is a descendant of Victoria's maternal 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 grandmother Princess Ingeborg of Denmark, a granddaughter of Christian IX.
In summation, the monarchs of Norway, Denmark and the United Kingdom as well as the consorts of the United Kingdom and Spain are descended from both Queen Victoria and Christian IX. The kings of Spain and Sweden are descended from Queen Victoria and not Christian IX. The King of Belgium is descended from Christian IX and not Queen Victoria. The King of the Netherlands is the only monarch descended from neither Queen Victoria nor Christian IX. (He is, however, a sixth cousin thrice removed of Elizabeth II, Prince Philip, Harald V, Margrethe II, Carl XVI Gustaf, Juan Carlos I, and Queen Sofía through descent from Frederick, Prince of Wales; and also a fourth cousin twice removed of Albert II through descent from William I of the Netherlands. Furthermore, William I of the Netherlands was also second cousin once removed to both Queen Victoria and King Christian IX, since he was the great-grandson of George II of Great Britain. Hence, all current reigning kings and queens in Europe, including the Netherlands, are related through the line of George II of Great Britain.)

Common ancestry between Victoria and 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, Landgrave 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. It is also interesting to note that 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 Landgrave Charles of Hesse-Kassel.
Thus King Christian IX of Denmark and his wife Louise of Hesse-Kassel were second cousins to each other and third cousins to Queen Victoria.
- When speaking of the present day descendants of Victoria and Christian IX, only those who are kings and queens or married to kings or queens are mentioned,[by whom?] to the exclusion of grand dukes, princes, etc.
- The designation of 'kingdom' excludes five other monarchies in Europe: the Principalities of Monaco, Liechtenstein and Andorra, the last of which is headed by a bishop (appointed by the Pope) and an elected president (of France); the Grand Duchy of Luxembourg; and Vatican City, whose leader, the Pope, is traditionally elected by the College of Cardinals.
