William, Prince of Wales in the context of "Baron of Renfrew (title)"

Charles III (Charles Philip Arthur George; born 14 November 1948) is King of the United Kingdom and 14 other Commonwealth realms.

Charles was born during the reign of his maternal grandfather, King George VI, and became heir apparent when his mother, Queen Elizabeth II, acceded to the throne in 1952. He was created Prince of Wales in 1958 and his investiture was held in 1969. Charles was educated at Cheam School and Gordonstoun, and later spent six months at the Timbertop campus of Geelong Grammar School in Victoria, Australia. After completing a history degree from the University of Cambridge, he served in the Royal Air Force and the Royal Navy from 1971 to 1976. He married Lady Diana Spencer in 1981 and they had two sons, William and Harry. Charles and Diana divorced in 1996 after years of estrangement and well-publicised extramarital affairs. Diana died the following year from injuries sustained in a car crash. In 2005, Charles married his long-time partner, Camilla Parker Bowles.

A prince is a male ruler (ranked below a king, grand prince, and grand duke) or a male member of a monarch's or former monarch's family. Prince is also a title of nobility (often highest), often hereditary, in some European states. The female equivalent is a princess. The English word derives, via the French word prince, from the Latin noun prīnceps, from primus (first) and caput (head), meaning "the first, foremost, the chief, most distinguished, noble ruler, prince".

In a related sense, now not commonly used, all more or less sovereign rulers over a state, including kings, were "princes" in the language of international politics. They normally had another title, for example king or duke. Many of these were Princes of the Holy Roman Empire.

The British royal family comprises King Charles III and other members of his family. There is no strict legal or formal definition of who is or is not a member, although the Royal Household has issued different lists outlining who is considered part of the royal family. Members typically support the monarch in carrying out public engagements and take part in charitable work and ceremonial duties.

Senior royals collectively undertake thousands of official engagements across the United Kingdom, British Overseas Territories, Crown Dependencies and abroad each year, including state visits, national events, and patronage activities. The family also represents the UK on the global stage and contributes to soft power through diplomacy and cultural presence.

Prince and Great Steward of Scotland (Scottish Gaelic: Prionnsa agus Mòr-stiùbhard na h-Alba; Scots: Prince an Great Stewart o Scotland) is one of the titles of the heir apparent to the British throne. The holder since 8 September 2022 is Prince William, who bears the other Scottish titles of Duke of Rothesay, Earl of Carrick, Lord of the Isles and Baron of Renfrew.

Diana, Princess of Wales (born Diana Frances Spencer; 1 July 1961 – 31 August 1997), was a member of the British royal family. She was the first wife of Charles III (then Prince of Wales) and mother of Princes William and Harry. Her activism and glamour made her an international icon and earned her enduring popularity.

Diana was born into the British nobility and grew up close to the royal family, living at Park House on their Sandringham estate. In 1981, while working as a nursery teacher's assistant, she became engaged to Charles, the eldest son of Queen Elizabeth II. Their wedding took place at St Paul's Cathedral in July 1981 and made her Princess of Wales, a role in which she was enthusiastically received by the public. The couple had two sons, William and Harry, who were then respectively second and third in the line of succession to the British throne. Diana's marriage to Charles suffered due to their incompatibility and extramarital affairs. They separated in 1992, soon after the breakdown of their relationship became public knowledge. Their marital difficulties were widely publicised, and the couple divorced in 1996.

Prince Harry, Duke of Sussex (Henry Charles Albert David; born 15 September 1984), is a member of the British royal family. As the younger son of King Charles III and Diana, Princess of Wales, he is fifth in the line of succession to the British throne.

Educated at Wetherby School, Ludgrove School, and Eton College, Harry completed officer training at the Royal Military Academy Sandhurst. He was commissioned as a cornet into the Blues and Royals and served briefly alongside his older brother, William. Harry was deployed twice on active duty to Afghanistan; first for 10 weeks in Helmand Province during 2007–2008, and then for 20 weeks with the Army Air Corps in 2012–2013.

Succession to the British throne is determined by descent, sex, legitimacy, and religion. Under common law, the Crown is inherited by a sovereign's children or by a childless sovereign's nearest collateral line. The Bill of Rights 1689 and the Act of Settlement 1701 restrict succession to the throne to the legitimate Protestant descendants of Sophia of Hanover who are in "communion with the Church of England". Spouses of Catholics were disqualified from 1689 until the law was amended in 2015. Protestant descendants of those excluded for being Roman Catholics are eligible.

King Charles III has been the sovereign since 2022, and his heir apparent is his elder son, William, Prince of Wales. William's three children are next, in order of birth: Prince George, Princess Charlotte, and Prince Louis. Fifth in line is Prince Harry, Duke of Sussex, the younger son of the King; sixth is Harry's elder child, Prince Archie. Under the Perth Agreement, which came into effect in 2015, only the first six in line of succession require the sovereign's consent before they marry; without such consent, they and their children would be disqualified from succession.
