Prince William, Duke of Cambridge: Titles, Family & Succession

When Queen Elizabeth II bestowed the title Duke of Cambridge upon Prince William in April 2011, few predicted how dramatically the royal title landscape would shift over the following decade. By 2022, William had traded that dukedom for something far more consequential: the Prince of Wales title held by heirs apparent for centuries. Understanding the mechanics behind these shifts matters more than ever given King Charles III’s cancer diagnosis and the accelerated conversation about the monarchy’s future.

Born: 21 June 1982 · Age: 42 · Current Primary Title: Prince of Wales · Former Title: Duke of Cambridge (2011-2022) · Children: 3

The table below summarizes key identifying and professional details about Prince William.

Is Prince William still the Duke of Cambridge?

No — Prince William no longer holds the Duke of Cambridge title. While the title remains part of his honorific history, it effectively merged with the Crown when King Charles III ascended the throne on 8 September 2022. The transition was not simply ceremonial. It marked the beginning of a new phase in William’s preparation for kingship.

Title change upon Charles III accession

Upon Queen Elizabeth II’s death and Charles III’s accession, William automatically inherited several Scottish and English dukedoms through the mechanism of succession. He became Duke of Cornwall, Duke of Rothesay, Earl of Carrick, Baron of Renfrew, Lord of the Isles, and Prince and Great Steward of Scotland. From 8 to 9 September 2022, he was styled as “His Royal Highness The Duke of Cornwall and Cambridge” before the formal Prince of Wales announcement followed.

Current titles: Prince of Wales and Duke of Cornwall

King Charles III announced William’s creation as Prince of Wales on 9 September 2022 — the same title Charles himself held during his decades as heir apparent. Letters patent formally granting this title, along with Earl of Chester, were issued on 13 February 2023. In Scotland, William is styled as “His Royal Highness The Duke of Rothesay” rather than Prince of Wales — a regional distinction that reflects the separate Scottish honorific system.

The implication: William’s title portfolio shifted from a single substantive dukedom to a constellation of roles reflecting his position as first in line. The Prince of Wales title, dating to the 14th century as a symbol for the heir apparent, carries both ceremonial weight and political sensitivity — Welsh nationalists have continued to question its relevance in a modern United Kingdom.

What will Kate Middleton be called when William is King?

When William ascends the throne, Catherine will become Queen Consort — the formal title for a queen married to a king. This mirrors historical precedent set by Queen Elizabeth The Queen Mother, who held the consort title during King George VI’s reign. Kate’s current Princess of Wales title, which she received when William became Prince of Wales in 2022, will be superseded by the higher consort designation.

Queen Consort title

The Queen Consort title distinguishes a reigning queen’s spouse from a queen who rules in her own right. Catherine will be William’s queen consort — the same title Camilla currently holds alongside King Charles III. When William’s reign ends and George becomes king, Catherine will transition to Queen Mother, following the pattern established by Elizabeth Bowes-Lyon after George VI’s death in 1952.

Comparison to current Princess of Wales

The Princess of Wales title, which William’s mother Princess Diana once held, has belonged to Catherine since September 2022. It serves as the principal title for the heir apparent’s wife. When William becomes king, Catherine will retain the Princess of Wales honorific as a subsidiary title while adding Queen Consort as her primary designation. The Telegraph reported that William and Catherine were granted authority to issue royal warrants starting spring 2026 — a significant marker of their expanding operational role.

What this means: Catherine’s title trajectory mirrors her husband’s elevation. The Princess of Wales role is transitional — a waypoint between royal spouse and eventual queen consort. Her preparation for that role includes current responsibilities that directly exercise royal authority.

What will Princess Charlotte be called when William is King?

Princess Charlotte’s future title depends on two factors: her eventual position in the line of succession and whether Parliament approves any changes to royal succession rules. As third in line behind her father and elder brother, Charlotte currently holds a historically unprecedented position as a female royal who will not be displaced by a younger brother.

Prince George as next in line

Prince George, born in 2013, is second in line to the throne and will become Prince of Wales when his father William ascends — just as William became Prince of Wales upon Charles III’s accession. This follows centuries of tradition: the heir apparent receives the Prince of Wales title, typically along with Earl of Chester. George’s position as first son of the first son of the monarch places him unambiguously in the direct succession line.

Charlotte’s Princess of Wales title

Under current succession law, Charlotte’s place behind George is secure — the Perth Agreement, effective since 2015, ended the tradition of male-preference primogeniture for royals in the line of succession. When William becomes king and George becomes Prince of Wales, Charlotte will likely retain her Princess of Wales title as the heir apparent’s daughter. Some constitutional analysts speculate she might eventually receive the title Princess Royal, currently held by Princess Anne, though that designation requires royal prerogative to bestow.

The pattern: Charlotte’s titles will reflect her position — subordinate to George but senior to Louis. The Princess of Wales title may eventually pass to George’s wife, leaving Charlotte to potentially inherit a different designation based on her own position in the evolving monarchy.

What will Camilla be called when William becomes King?

Camilla Parker Bowles will hold the title Queen Consort during King Charles III’s reign, but her title will change dramatically once William ascends the throne. Upon William’s coronation, Camilla becomes Queen Mother — a title last held by Queen Elizabeth The Queen Mother after her husband King George VI died in 1952.

Queen Mother title

The Queen Mother designation applies to a former queen consort whose spouse has died and whose child now occupies the throne. Camilla would be the second queen consort to hold this title in modern British history, following Elizabeth Bowes-Lyon, who lived until 2002 and was widely known as the Queen Mother. The title distinguishes the dowager queen from the reigning queen consort — avoiding confusion between Camilla and William’s wife Catherine.

Historical precedents

Queen Victoria’s mother, Victoria Mary Louisa, held the title Dowager Queen following her husband’s death. The British monarchy has no formal protocol requiring “Queen Mother” — it emerged as a practical solution when Elizabeth Bowes-Lyon needed differentiation from her daughter Elizabeth II. Camilla’s transition to Queen Mother carries implicit downgrade from reigning consort to former consort, though the title itself carries dignity and historical weight.

The trade-off: Camilla moves from center stage to historical footnote status — yet retains royal honorifics. The title change reflects the monarchy’s implacable logic of succession: the moment Charles dies or abdicates, Camilla’s position transforms entirely.

What do William’s kids call Camilla?

Royal family dynamics around naming reveal the informal mechanisms that humanize an institution often perceived as distant and formal. Prince George, Princess Charlotte, and Prince Louis reportedly use “Grandma” or “Gan-Gan” for Queen Camilla — a nickname reportedly coined by Princess Charlotte herself during family gatherings.

Nicknames in family

The royal household maintains deliberate informality in private family settings, even as public roles demand formal designations. Catherine and William have reportedly encouraged their children to maintain warm relationships with both Camilla and their maternal grandparents. This balancing act — royal formality alongside genuine family affection — reflects how modern royals navigate between institutional requirements and personal relationships.

Kate’s nickname for Louis

Prince Louis, the youngest of William and Catherine’s children, reportedly has a tender nickname from his mother. Kate reportedly calls her youngest son “Louboutin” or shortens it to “Lou-Lou” in private moments. Whether accurate or apocryphal, these glimpses into royal family intimacy humanize figures often seen only in ceremonial contexts.

The catch: Royal family nicknames exist in a peculiar public domain — partially confirmed, partially rumor, constantly subject to media speculation. What matters is the underlying reality: William and Catherine are raising their children with access to both formal royal protocols and ordinary family warmth.

Timeline

Three pivotal moments defined Prince William’s title evolution across three decades.

The implication: William’s title evolution tracks the institution’s own preparation for transition. Each conferral builds toward eventual kingship — with increasing authority, expanded territory titles, and growing ceremonial responsibilities that prepare the heir for eventual coronation.
