Who Were William IV’s Children and Siblings?
Children with Dorothea Jordan
William IV had 10 children with the actress Dorothea Jordan, also known as Mrs. Jordan. These children were given the surname FitzClarence, as recorded by the Royal Household and Encyclopaedia Britannica. Because the couple was not married, all these children were illegitimate.
Marriage and Legitimate Children
In 1818, William married Princess Adelaide of Saxe-Meiningen. According to the official royal website, their children died in infancy. As a result, William IV had no surviving legitimate children.
Because none of William’s legitimate children survived, the British throne passed to his niece, Victoria. In Hanover, Salic law prevented Victoria from inheriting, so the crown went to William’s brother, Ernest Augustus, ending the personal union.
Siblings
William IV was one of 15 children born to King George III and Queen Charlotte. His elder brothers included George IV (who preceded him as king) and Frederick, Duke of York. His younger brothers included Ernest Augustus, who succeeded him in Hanover. This large family is detailed in the Wikipedia entry for the king.
What Was William IV’s Cause of Death and How Long Did He Reign?
Length of Reign
William IV reigned from 26 June 1830 to 20 June 1837, a period of about seven years. It was a relatively short reign, but one marked by significant political change, most notably the passage of the 1832 Reform Act.
Cause of Death
William IV died on 20 June 1837 at Windsor Castle. According to World History Encyclopedia and HistoryExtra, the official cause of death was pneumonia/bronchopneumonia and heart failure. Some sources also mention cirrhosis of the liver as a contributing factor. There is no evidence of any foul play.
Naval Career
William entered the Royal Navy at age 13 as a midshipman, serving for roughly 10 years. He saw service in British North America, the Caribbean, and during the American Revolutionary War. He rose to the rank of rear-admiral by 1790, though some accounts note this promotion was largely honorary.
In 1827, William was appointed Lord High Admiral, the first person to hold that office since 1709. This role, along with his early naval service, solidified his nickname of the “Sailor King” and fostered a friendship with the famous Admiral Horatio Nelson.
Who Preceded King William IV?
William IV’s predecessor was his elder brother, King George IV. George IV reigned from 1820 until his death on 26 June 1830. Because George IV had no surviving legitimate children, the throne passed to his next surviving brother, William. This transfer of power is documented by the official Royal Family website.

Historical Context and Significance
William IV’s reign was a transitional period between the personal rule of George IV and the Victorian era. His naval background influenced his pragmatism and support for reform, despite personal conservatism. The lack of legitimate heirs forced the succession to Victoria, leading to the end of the Hanoverian personal union. His legacy is often overshadowed by his flamboyant brother and his iconic niece, but his role in the Reform Act 1832 was crucial.
