William IV was the elder brother and successor of George IV. He was succeeded in the United Kingdom by his niece Queen Victoria, as he had no surviving legitimate children. In Hanover, the crown passed to his brother Ernest Augustus, Duke of Cumberland, ending the personal union between Britain and Hanover.
Did William IV Have Children?
William IV had a large family, but none of his children were legitimate heirs to the throne. From 1791, he lived with the actress Dorothea Jordan, and they had ten children together. These children used the surname FitzClarence and were all considered illegitimate under British law.
His Marriage to Princess Adelaide
In 1818, William married Princess Adelaide of Saxe-Meiningen. The marriage produced two daughters, but both died in infancy. This meant that when William died, he left no surviving legitimate children, and the British crown passed to his niece Victoria.
William IV had ten children with his mistress Dorothea Jordan. While historical records consistently state ten, there is minor variation in some accounts regarding possible stillbirths. The use of the surname FitzClarence is well-established.
What Was William IV’s Cause of Death?
William IV died on 20 June 1837 at Windsor Castle. According to Britroyals, his cause of death was heart failure. Some historical sources also describe his final illness as “dropsy,” a condition characterised by fluid retention, which is consistent with cardiac issues.
How Long Did William IV Reign?
William IV’s reign lasted from 26 June 1830 until his death on 20 June 1837 – a total of seven years. He became king at the age of 64, succeeding his brother George IV.
His reign is especially associated with the Reform Act of 1832, which redistributed parliamentary seats away from “rotten boroughs” toward industrial districts and reduced the political power of the crown and landed aristocracy. Although he was personally opposed to the reform, he accepted the act. Other notable reforms during his reign included changes to the Poor Law, child labour regulations, and the abolition of slavery in most of the British Empire with the Slavery Abolition Act of 1833.
Who Were William IV’s Parents and Siblings?
William was the third son of George III and Queen Charlotte (Charlotte of Mecklenburg-Strelitz). His elder brothers included George IV and Frederick, Duke of York. Among his younger siblings was Edward, Duke of Kent, who would become the father of Queen Victoria.
In total, George III and Queen Charlotte had 15 children, though not all survived to adulthood. The family was large and often turbulent, with the mental illness of George III casting a long shadow over his children’s lives.
What Is the William IV Pub?
The “William IV” is a common name for pubs and public houses across the United Kingdom, named in honour of the monarch. These establishments are not a single chain but rather independent venues that adopted the king’s name, often in the years following his reign. They can be found in various towns and cities, serving as a local reminder of the “Sailor King.”
How Long Did William IV Serve in the Navy?
William entered the Royal Navy at age 13 and served actively from 1779. He served in the West Indies, British North America, and Nova Scotia, and was friendly with Horatio Nelson. When he left active service in 1790, he had become unpopular with some fellow officers and had angered his father because of his love affairs. He was appointed Lord High Admiral in 1827, the first holder of that office since 1709.

What Was the Historical Context of William IV’s Reign?
William IV came to power after the unpopular reign of his brother George IV, and his more modest lifestyle helped restore public faith in the monarchy. His reign saw the first major parliamentary reform (1832) and the abolition of slavery (1833), both reflecting the rising influence of the middle classes and humanitarian movements. As the last king of the House of Hanover to rule the United Kingdom and Hanover in personal union, his death marked the end of that union (Salic law prevented Victoria from inheriting Hanover). His naval experience gave him a pragmatic, unpretentious style, but also led to conflicts with political leaders like Lord Grey.
Salic law, which governed succession in Hanover, prevented Queen Victoria from inheriting that throne. This is why William IV’s brother Ernest Augustus became King of Hanover after his death, ending the personal union between the two kingdoms that had existed since 1714.
