How Many King Williams Have There Been – 4 English Monarchs Explained

Oliver Alfie Bennett Thompson • 2026-04-05 • Reviewed by Ethan Collins

English royal history records exactly four kings bearing the name William. These monarchs span nearly eight centuries of British governance, from the Norman invasion of 1066 through the dawn of the Victorian era.

The line begins with William the Conqueror, whose victory at Hastings transformed the Anglo-Saxon kingdom into a Norman state. It concludes with William IV, whose death in 1837 ended the personal union between Britain and Hanover while ushering in Queen Victoria’s reign.

Between these two points stand William II, killed during a royal hunt, and William III, who arrived from the Netherlands to secure Protestant succession. No fifth William has ever occupied the English throne.

Who Were the Four Kings Named William?

William I (c. 1028–1087)

Born the illegitimate son of Robert I, Duke of Normandy, William I secured his hold on Normandy through military campaigns including the Battle of Val-ès-Dunes in 1047. His invasion of England in 1066 culminated in the Battle of Hastings on 14 October, where Harold Godwinson fell. Crowned in Westminster Abbey on Christmas Day, he commissioned the Domesday Book survey in 1086 and died during a campaign in France in 1087.

William II (c. 1056–1100)

Known as “Rufus” for his red hair, William II inherited England while his elder brother Robert Curthose received Normandy. His thirteen-year reign featured conflicts with the church and ongoing tensions with Robert. On 2 August 1100, he died from an arrow wound sustained while hunting in the New Forest, possibly murdered, though historical consensus remains divided.

Domesday Survey

In 1086, William I ordered the comprehensive survey of England known as the Domesday Book, creating a detailed record of landholdings that remains a crucial medieval historical source.

William III (1650–1702)

The Dutch Stadtholder of the Netherlands arrived in England during the Glorious Revolution of 1688, deposing James II. William III ruled jointly with his wife Mary II until her death in 1694, securing Protestant rule at the Battle of the Boyne in 1690. His childless death precipitated the Act of Settlement 1701.

William IV (1765–1837)

The third son of George III earned his nickname “Sailor King” from his extensive Royal Navy career. William IV reigned barely seven years, yet included the passage of the Reform Act 1832 which eliminated corrupt electoral districts. He died without surviving legitimate children, leaving the throne to his niece Victoria.

What Major Achievements Defined Each Reign?

Administrative Revolution

William I restructured English feudalism, replacing over 4,000 Anglo-Saxon landholders with approximately 200 Norman lords. He constructed motte-and-bailey castles across the realm, including the White Tower at the Tower of London, and installed Lanfranc as Archbishop of Canterbury to reform the church.

Norman Consolidation

William II maintained Norman control through military presence and ruthless governance. His reign continued the centralization of royal authority begun by his father, though he initiated no major administrative reforms recorded in historical sources.

Constitutional Monarchy

William III helped establish the constitutional monarchy framework accepted today. He formed the Grand Alliance against Louis XIV of France and defeated Jacobite forces threatening the Protestant succession. His reign marked the final shift from absolute to parliamentary authority.

Constitutional Legacy

William III’s acceptance of the Declaration of Rights in 1689 established the precedent that English monarchs ruled with the consent of Parliament, fundamentally limiting royal prerogative.

Reform Era

Despite his brief reign, William IV supported the 1832 Reform Act that expanded suffrage and eliminated “rotten boroughs.” His opposition to slavery and recognition of reform governments marked a transition toward modern parliamentary democracy.

Why Did the Line End at William IV?

William IV died on 20 June 1837 without surviving legitimate children. Under the rules of succession then in effect, the crown passed to his niece Victoria, beginning the Victorian age. The personal union between Britain and Hanover ended because Hanover operated under Salic law barring female succession.
