William, Prince of Wales

In Royal Air Force uniform at the 2010 Trooping the Colour

Having decided to follow a military career, William was admitted to the Royal Military Academy Sandhurst in January 2006.[43] As "Lieutenant Wales"—a name based on his father's title Prince of Wales—he followed his younger brother[44] into the Blues and Royals as a troop commander in an armoured reconnaissance unit, after which he spent five months training for the post at Bovington Camp, Dorset.[45]

William's position as second-in-line to the throne at the time and the convention of ministers advising against placing that person into dangerous situations cast doubts on his chances of seeing combat, which increased after Prince Harry's deployment was cancelled in 2007 due to "specific threats". William, instead, went on to train in the Royal Navy and Royal Air Force, obtaining his commission as a sub-lieutenant in the former and flying officer in the latter—both broadly equivalent to the army rank of lieutenant.

After completing his training, William undertook an attachment with the Royal Air Force at RAF Cranwell.[46][47] Upon completing the course he was presented with his RAF wings by his father,[48] who had received his own wings after training at Cranwell.[49] During this secondment, William flew to Afghanistan in a C-17 Globemaster that repatriated the body of Trooper Robert Pearson.[50] William was then seconded to train with the Royal Navy.[51] He completed an accelerated Naval Officer training course at the Britannia Royal Naval College.[52] Whilst serving on HMS Iron Duke in June 2008, William participated in a £40m drug seizure in the Atlantic, north-east of Barbados.[53] He was a part of the crew on the Lynx helicopter which helped seize 900 kg of cocaine from a speedboat.[54]

William piloting a Sea King helicopter in 2010

In January 2009, William transferred his commission to the RAF and was promoted to Flight Lieutenant. He trained to become a helicopter pilot with the RAF's Search and Rescue Force. In January 2010, he graduated from the Defence Helicopter Flying School at RAF Shawbury.[55] On 26 January 2010, he transferred to the Search and Rescue Training Unit at RAF Valley, Anglesey, to receive training on the Sea King search and rescue helicopter; he graduated in September 2010.[56] This made him the first member of the British royal family since Henry VII to live in Wales.[57]

William's first rescue mission as co-pilot of an RAF Sea King was a response to an emergency call from Liverpool Coastguard on 2 October 2010.[58] In November 2011, he participated in a search-and-rescue mission involving a cargo ship that was sinking in the Irish Sea; William, as a co-pilot, helped rescue two sailors.[59]

William was deployed to the Falkland Islands for a six-week tour with No. 1564 Flight from February to March 2012.[60][61] The Argentine government condemned William's deployment to the islands close to the 30th anniversary of the beginning of the Falklands War as a "provocative act".[62][63] In June 2012, Prince William gained a qualification to be captain or pilot in command of a Sea King rather than a co-pilot.[64] His active service as an RAF search-and-rescue pilot ended in September 2013.[65][66] He later became patron to the Battle of Britain Memorial Flight.[67]

In 2014, it was announced that William would accept a full-time role as a pilot with the East Anglian Air Ambulance (EAAA) based at Cambridge Airport. Despite his qualifications as a military helicopter pilot, William needed a civil pilot's licence and further training before being permitted to take command of the Air Ambulance. Although his position was paid, Kensington Palace announced that William would donate his full salary to the EAAA charity.[68] He underwent part of his training as an EAAA pilot at Norwich Airport.[69] On 13 July 2015, William started his new job, which he felt was a natural progression from his previous role as an RAF search-and-rescue pilot.[70] William described working irregular shifts and dealing mostly with critical care cases.[71] He also publicly discussed the consequences, witnessing intensive trauma and bereavement as an emergency worker, stating that it impacted his mental health and personal life.[72] The BBC has written that William was "exposed to the National Health Service in a way that no other senior royal has been or possibly ever will be."[73]

William left his position with EAAA in July 2017 to assume full-time royal duties on behalf of his grandmother.[74][73] After supporting an anniversary campaign for London's Air Ambulance Charity in 2019, he became the charity's official patron in March 2020.[75] In May 2020, he granted permission to the charity to use Kensington Palace's private lawn to refuel during the COVID-19 pandemic.[76] To mark Air Ambulance Week 2020, he wrote a letter thanking air ambulance workers, stating his "profound respect" for the community, particularly during the "immeasurably difficult" outbreak, and stated that "the country owes you an enormous debt of gratitude."[77][78]

In 2001, William met Catherine Middleton while they were students in residence at St Salvator's Hall at the University of St Andrews.[79] She reportedly caught William's attention at a charity fashion show on campus.[80] The couple began dating in 2003.[81] During their second year, William shared a flat with Middleton and two other friends.[82] From 2003 to 2005, they both resided at Balgove House on the Strathtyrum estate with two roommates.[83][84] In 2004, the couple briefly split but continued their relationship soon afterwards.[85]

Their relationship was followed so closely by the tabloid press that bookmakers took bets on the possibility of marriage, and the retail chain Woolworths produced memorabilia bearing their likenesses.[86] Media attention became so intense that William asked the press to keep their distance from Middleton.[86] On 15 December 2006, Middleton attended Prince William's Passing Out Parade at the Royal Military Academy Sandhurst.[87][88]

In April 2007, William and Middleton ended their relationship.[89] Middleton and her family attended the Concert for Diana in July 2007 at Wembley Stadium,[82] where she and Prince William sat two rows apart. The couple were subsequently seen together in public on a number of occasions and news sources stated that they had "rekindled their relationship".[90] Middleton was in attendance during the Order of the Garter procession ceremony at Windsor Castle in June 2008, where Prince William was made a Royal Knight of the Garter.[91] In June 2010, the couple moved into a cottage on the Bodorgan Estate in Anglesey, Wales, where William resided during his RAF search-and-rescue training and subsequent career.[92][93][94]

With his family at Trooping the Colour 2019

On 16 November 2010, Clarence House announced that William and Catherine were to marry; the couple had become engaged in Kenya in October.[95] The engagement ring given by William to Catherine had belonged to his mother. The wedding took place on 29 April 2011 in Westminster Abbey, London.[96] A few hours before the ceremony, William's new titles Duke of Cambridge, Earl of Strathearn, and Baron Carrickfergus were announced.[97][98][99][100] Estimates of the global audience for the wedding ranged around 300 million or more, whilst 26 million watched the event live in Britain alone.[101][102][103] The couple were given the country home, Anmer Hall, on the Sandringham Estate, as a wedding gift from the Queen.[104] Following their marriage in 2011, William and Catherine used Nottingham Cottage as their London residence.[105] They moved into the four-storey, 20-room Apartment 1A at Kensington Palace in 2013. Renovations took 18 months at a cost of £4.5 million.[106] Kensington Palace became the couple's main residence in 2017, moving from their country home, Anmer Hall.[107] In 2022, it was announced that the couple, along with their children, would move to Adelaide Cottage in Windsor.[108]

Catherine's first pregnancy was announced on 3 December 2012.[109] She was admitted on 22 July 2013 to the Lindo Wing of St Mary's Hospital, London, where Prince William had been delivered. Later that day, she gave birth to Prince George.[110][111] On 8 September 2014, it was announced that Catherine was pregnant with her second child.[112] She was admitted on 2 May 2015 to the same hospital and gave birth to Princess Charlotte.[113] Catherine's third pregnancy was announced on 4 September 2017;[114] Prince Louis was born on 23 April 2018.[115]

William and Catherine have owned two English Cocker Spaniels, named Lupo and Orla.[116][117] William is the godfather of Prince Constantine Alexios of Greece and Denmark (b. 1998), a distant relation through his grandfather, the Duke of Edinburgh, and Mia Tindall (b. 2014), the eldest child of his paternal cousin, Zara Tindall.[118][119]

William and his brother Harry inherited the "bulk" of the £12.9 million left by their mother on their respective 30th birthdays, a figure that had grown since her 1997 death to £10 million each in 2014.[120][121] In 2002, The Times reported that William would also share with his brother a payment of £4.9 million from trust funds established by their great-grandmother, Queen Elizabeth The Queen Mother, on their respective 21st birthdays and would share a payment of £8 million upon their respective 40th birthdays.[122] It was reported that Harry would inherit the bulk of the money left by the Queen Mother for the two brothers, as William is set to ascend to the throne which will bring him more financial benefits.[123] As the eldest son of the King, William has inherited the Duchy of Cornwall, which brings him an additional income.[124]

In 2014, the brothers inherited their mother's wedding dress along with many other of her personal possessions including dresses, diamond tiaras, jewels, letters, and paintings. The brothers also received the original lyrics and score of "Candle in the Wind" by Bernie Taupin and Elton John as performed by John at Diana's funeral.[121]

On 3 June 1991, William was admitted to Royal Berkshire Hospital after being accidentally hit on the forehead by a fellow pupil wielding a golf club. He suffered a depressed fracture of the skull and was operated on at Great Ormond Street Hospital, resulting in a permanent scar.[125] News of this incident spread quickly and media reporters descended on Ludgrove School to seek the name of the boy who had swung the golf club, but nobody divulged the name after the headmaster briefed his pupils and swore them to silence.[27] In a 2009 interview, he dubbed the resulting scar a "Harry Potter scar" and said, "I call it that because it glows sometimes and some people notice it—other times they don't notice it at all".[126] In 1999, he underwent an operation on his left hand after he broke a finger.[127]

On 1 November 2020, it was reported that William had tested positive for COVID-19 in April but decided not to alert the media to 'avoid alarming the nation'.[128] The Daily Telegraph reported he had been "very ill" and had isolated away from his family;[129] other sources say that he had not been seriously ill, not bed-ridden and working for most of the time.[130]

William became aware of HIV/AIDS in the mid-1990s when he accompanied his mother and brother on visits to shelters and clinics for patients. In January 2005, William and his brother volunteered at a British Red Cross aid distribution centre to pack emergency supplies for countries affected by the 2004 Boxing Day tsunami.[204] In 2005, William worked in the children's unit at The Royal Marsden Hospital, his mother's former patronage, for two days of work experience; he also assisted in the medical research, catering, and fundraising departments.[205] In May that year, he spent two weeks in North Wales with Mountain Rescue England and Wales (MREW).[204] In May 2007, William became patron of MREW and president of The Royal Marsden Hospital, the latter of which was a role previously held by his mother.[205][206] In October 2020, William laid the foundation stone of the hospital's Oak Cancer Centre, 30 years after his mother did the same for their Chelsea Wing in 1990.[207]

In 2007, William and Harry organised the Concert for Diana, in memory of their mother, which benefitted the charities and patronages of Diana, William, and Harry.[208] In October 2008, William and his brother embarked on the 1,000 mile eight-day Enduro Africa motorbike ride across South Africa to raise money for Sentebale, UNICEF and the Nelson Mandela Children's Fund.[209] In 2010, he also became a patron of 100 Women in Hedge Funds Philanthropic Initiatives.[210] William succeeded Lord Attenborough in 2010 as the fifth president of the British Academy of Film and Television Arts.[211] In March 2011, William and Catherine set up a gift fund held by The Foundation of Prince William and Prince Harry to allow well-wishers who wanted to give them a wedding gift to donate money to charities instead.[212] The gift fund supported 26 charities of the couple's choice, incorporating the armed forces, children, the elderly, art, sport and conservation.[213][214][215][216] The charity has since been renamed The Royal Foundation.[217]

William has spoken out for LGBT rights as part of his work against cyberbullying, stating the importance of being "proud of the person you are" and discussing the effects of online abuse and discrimination.[218] In 2016, he appeared in the July issue of Attitude and became the first member of the royal family to be featured on the cover of a gay magazine.[219] He was recognised at the British LGBT Awards in May 2017.[218]

In March 2020, William appeared in a video for the National Emergencies Trust, launching a fundraising appeal to help charities during the pandemic. The appeal raised £11 million in its first week, eventually totalling to £90 million, with the money going out to "front line charities" and to the UK Community Foundations to be distributed among "local community foundations".[220][221] In April 2020, he officially became the patron of the organisation.[222] In April 2020, he made a surprise appearance in The Big Night In, a 20 April 2020 telethon held during the COVID-19 pandemic, in a skit which he held a video call with Stephen Fry, who revised his role as (a descendant of) Lord Melchett, from the Blackadder series.[223]

In May and June 2020, the couple, alongside their children, delivered food parcels made on the Sandringham Estate to local isolated pensioners during the COVID-19 pandemic.[224][225] In December 2020, the couple became joint patrons of NHS Charities Together.[226]

In February 2021, William visited a vaccination centre in King's Lynn and later encouraged use of the vaccine, denouncing false information that could cause vaccine hesitancy.[227][228] In May 2021, he got his first dose of COVID-19 vaccine by NHS staff at the Science Museum in London.[229] In September 2021, it was reported that William had helped an Afghan officer who was a graduate of the Royal Military Academy Sandhurst and an assistant to the British troops be evacuated from the Kabul airport along with more than 10 members of his family amid the 2021 Taliban offensive.[230]

In March 2022 and amid the Russian invasion of Ukraine, William and Catherine made a donation to help the refugees.[231]

At a United for Wildlife Taskforce Meeting at Buckingham Palace, 2017

Prince William became a patron of the Tusk Trust in December 2005,[205] a charity that works towards conserving wildlife and initiating community development, including providing education, across Africa.[232] He became associated with the organisation after he witnessed its work first hand in Africa. Stating that "rural African initiatives that foster education, responsibility and participation in the local community light the way to conservation",[233] he carried out his first official duty with the trust in launching a 5,000-mile (8,000 km) bike ride across the African continent in 2008.[234] Later, William helped with launching the Tusk Conservation Awards, which have been presented to selected environmental activists annually since 2013.[235] William has occasionally commented on the effects of overpopulation on the wildlife of Africa, but his remarks have been criticised for not taking resource consumption and population density into consideration, both of which affect wildlife in rich and developed countries.[236] In December 2014, he founded the United for Wildlife Transport Taskforce, which aims to reduce worldwide illegal wildlife trade.[237]

After two years of research, William launched the Earthshot Prize in October 2020, designed to provide funding and incentive for environmental solutions over the next decade. The Prize is slated to be given every year from 2021 until 2030 to five winners each year, in accordance with five categories detailing the restoration of nature, air cleanliness, ocean conservation, waste-free living, and climate change. The selection process will be performed by the Prince, alongside a council of judges from six continents, overseen by a panel of experts. The first awards ceremony is slated to take place in London in autumn 2021.[238] Following the launch, William gave a TED Talk on environmental protection and conservation as part of the TED Countdown climate change initiative.[239] Later that month, William took over the patronages of Fauna and Flora International and the British Trust for Ornithology, passed on from the Queen and Prince Philip.[240] In the same month, he appeared in an ITV documentary titled Prince William: A Planet For Us All to discuss environmental issues.[241]

In early 2021, William made a private donation to the Thin Green Line Foundation, which provides grants for the relatives of conservation park rangers that are killed every year while protecting wildlife.[242] In July 2022, William condemned the murder of South African park ranger Anton Mzimba and asked for the responsible parties to "be brought to justice".[243] In August 2022, he voiced his support for the 63-month prison sentence given in the United States to a man responsible for trafficking rhinoceros horns and elephant ivory, calling it "a significant victory".[244] He had previously called for harsher punishments and penalties for poachers and smugglers at the Illegal Wildlife Trade Conference in 2018.[245]

Since 2009, William has been the patron of Child Bereavement UK, which provides support for children and families who have lost a loved one.[246] In 2016, the Royal Foundation launched multiple mental health initiatives, including Heads Together, a campaign led by William, Catherine and Prince Harry to de-stigmatise mental health.[247] Legacy programmes include Mental Health at Work, launched in September 2018 to change the approach to workplace mental health in the UK, as well as Heads Up, launched in May 2019 in partnership with the Football Association, utilising football to affect the conversation surrounding mental health in adults.[248][249] Later that month, the couple together with William's brother and sister-in-law launched Shout, the UK's first 24/7 text messaging service for those who suffer from mental issues.[250] William later volunteered on the crisis helpline during the COVID-19 lockdowns to provide support via text message.[251] In October 2019, the Prince, together with other members of the royal family, voiced a PSA video for Public Health England "as part of its Every Mind Matters program".[252] William has cited his interest in mental health to his experiences as an air ambulance pilot, as well as his work with homelessness, veterans welfare, and his wife's advocacy on addiction.[253]

In late March 2020, William and Catherine began supporting a new mental health initiative by the Public Health England amidst the coronavirus pandemic.[254] In April 2020, the couple announced Our Frontline, an initiative providing mental health support to emergency medical workers.[255] In May 2020, the couple's recorded radio message for Mental Health Awareness Week was broadcast across all the stations in the UK.[256] In June 2020, William stated that he had been serving as a volunteer on the Shout hotline during the pandemic.[257] In September 2020, he established the Emergency Responders Senior Leaders Board, commissioned by the foundation to research the mental health and wellbeing of emergency responders.[258] The project is in partnership with King's College London and the Open University.

To commemorate World Mental Health Day on 11 October 2021, William and Catherine posted a message on Instagram, sharing several organisations that support those who are struggling with mental health.[259] In May 2021 and 2022, William and Catherine voiced the Mental Health Minute message, which was broadcast on every radio station in the UK on and asked people to help individuals around them that suffer from loneliness.[260][261] In October 2022 and to mark the World Mental Health Day, the couple took over Newsbeat and interviewed four guests on topics related to mental health.[262]

In September 2005, William granted his patronage to Centrepoint, a charity that assists the homeless.[205][263] In December 2009, he, as part of a Centrepoint-organised event, spent the night sleeping bag near the Blackfriars Bridge to raise awareness of the experiences of homeless youth.[264] The Prince opened their new facility, Apprenticeship House, in November 2019 to mark their 50-year anniversary.[265]

William has been patron of homelessness charity The Passage since 2019 after first visiting the centre in 1992 with his mother.[266] In October 2020, he wrote the introduction to the organisation's 40th-anniversary fundraising cookbook, discussing the importance of helping victims of homelessness during the COVID-19 pandemic.[267] In December 2020, William volunteered at the charity to help prepare donation bags for homeless residents in emergency hotel accommodations and spoke with residents about their experiences.[268] In March 2022, he was spotted selling copies of The Big Issue on the streets, copies of which are usually sold by homeless and unemployed people to collect money.[269]

Playing polo at Sandhurst, 2007

William often plays polo to raise money for charity.[270] He is a fan of football, and supports the English club Aston Villa.[271] He became President of England's Football Association in May 2006 and vice-royal patron of the Welsh Rugby Union (WRU) in February 2007, supporting the Queen as patron.[205] The same year, the WRU's decision to name a new cup for test matches between Wales and South Africa the Prince William Cup caused controversy; some believed it would have been more appropriate to name it after Ray Gravell.[272][273][274] In December 2010, William and Prime Minister David Cameron attended a meeting with FIFA vice-president Chung Mong-joon at which Chung suggested a vote-trading deal for the right to host the 2018 World Cup in England. The English delegation reported the suggestion to FIFA's ethics investigator because they considered vote-swapping to be a violation of anti-collusion rules.[275][276] In 2011, William as President of the English FA, voted against Australia's 2022 FIFA bid and instead voted for South Korea; despite being the country's future heir. In 2020, again as President of the English FA, he voted against the joint Australia–New Zealand 2023 FIFA Women's World Cup bid and instead voted for Colombia.[277]

In February 2021, following an investigation into racism directed at Marcus Rashford, William released a statement as president of the FA, denouncing the "racist abuse... whether on the pitch, in the stands, or on social media" as "despicable" and stating that "we all have a responsibility" to create an environment of tolerance and accountability.[278] In April 2021, William criticised the planned breakaway competition The Super League, adding that he "share[d] the concerns of fans about the proposed Super League and the damage it risks causing to the game we love."[279] In July 2021, he condemned racist attacks against England football players following their loss at the UEFA Euro 2020 finale.[280]

In 2006, William, along with other Sandhurst officers, took part in a one-mile (1.6 km) run to support the charity Sport Relief, as he had done in 2004 with a team from Clarence House. In May 2007, William became patron of the English Schools' Swimming Association.[205] In 2012, together with his wife Catherine and Prince Harry, William launched Coach Core. The program was set up following the 2012 Olympics and provides apprenticeship opportunities for people who desire to pursue a career as a professional coach.[281] In 2013, he succeeded his grandfather Prince Philip, Duke of Edinburgh, as president of the UK charity Fields in Trust.[282] In 2014, he and Catherine were awarded Honorary Life Membership of the Marylebone Cricket Club.[283] In May 2020, he appeared in a BBC One Documentary titled Football, Prince William and Our Mental Health as a part of a campaign to promote men to discuss their mental issues using football as a common medium.[284]

Both William and his brother are enthusiastic motorcyclists; William owns a Ducati 1198 S Corse.[285] In May 2014, William, like his father and paternal grandfather, became president of the British Sub-Aqua Club (BSAC).[286] He enthusiastically took part in a bandy event in Stockholm in January 2018.[287]

William has been a British prince since birth. On his wedding day, 29 April 2011, his grandmother Elizabeth II created him Duke of Cambridge, Earl of Strathearn and Baron Carrickfergus. The letters patent granting these titles were issued on 26 May that year.[313][314]

On the accession of his father on 8 September 2022, as the eldest son of the monarch, he automatically became Duke of Cornwall, Duke of Rothesay, Earl of Carrick, Baron of Renfrew, Lord of the Isles, and Prince and Great Steward of Scotland.[315][316] On 9 September 2022, the King announced the creation of William as Prince of Wales.[317]

Royal monogram

• 1982 – 29 April 2011: His Royal Highness Prince William of Wales
• 29 April 2011 – 8 September 2022: His Royal Highness The Duke of Cambridge[318]
  • In Scotland: 29 April 2011 – 8 September 2022: His Royal Highness The Earl of Strathearn[319]

  • In Scotland: 8 September 2022 – present: His Royal Highness The Duke of Rothesay[321][lower-alpha 3]
• 9 September 2022 – present: His Royal Highness The Prince of Wales[322]

Two forms of address are in current use; in Scotland he is known by his highest Scottish title, Duke of Rothesay, and elsewhere by his highest British title, Prince of Wales.[323]

He is a Royal Knight Companion of the Most Noble Order of the Garter (KG),[324] a Knight of the Most Ancient and Most Noble Order of the Thistle (KT),[325] a member of the Privy Council of the United Kingdom (PC),[326][327] and a Personal Aide-de-Camp (ADC) to the sovereign.[328]

The banners used by the Prince of Wales vary depending upon location. His personal standard is the Royal Standard of the United Kingdom differenced as in his arms with a label of three points Argent, and the escutcheon of the arms of the Principality of Wales in the centre. It is used outside Wales, Scotland, Cornwall, and Canada, and throughout the entire United Kingdom when the prince is acting in an official capacity associated with the UK Armed Forces.[331]

The personal flag for use in Wales is based upon the Royal Badge of Wales (the historic arms of the Kingdom of Gwynedd), which consist of four quadrants, the first and fourth with a red lion on a gold field, and the second and third with a gold lion on a red field. Superimposed is an escutcheon Vert bearing the single-arched coronet of the Prince of Wales.[331]

In Scotland, the personal banner used since 1974 is based upon three ancient Scottish titles: Duke of Rothesay (heir apparent to the King of Scots), High Steward of Scotland and Lord of the Isles. The flag is divided into four quadrants like the arms of the Chief of Clan Stewart of Appin; the first and fourth quadrants comprise a gold field with a blue and silver checkered band in the centre; the second and third quadrants display a black galley on a silver field. The arms are differenced from those of Appin by the addition of an inescutcheon bearing the tressured lion rampant of Scotland; defaced by a plain label of three points Azure to indicate the heir apparent.[331]

In Cornwall, the banner is the arms of the Duke of Cornwall: "Sable 15 bezants Or", that is, a black field bearing 15 gold coins.[331]

In Canada, a personal heraldic banner for the Prince of Wales was first issued in 2011, consisting of the shield of the Arms of Canada defaced with both a blue roundel of the Prince of Wales's feathers surrounded by a wreath of gold maple leaves, and a white label of three points.[332]

Prior to the accession of his father, William used a banner derived from his arms, for use outside of Scotland and Canada. There was a variation of this used when in Scotland. In 2011, the Canadian Heraldic Authority introduced a personal heraldic flag for the Duke of Cambridge's use in Canada. It is the Royal Arms of Canada in banner form defaced with a blue roundel surrounded with a wreath of gold maple leaves and shells within which is a depiction of a "W" surmounted by a coronet. Above the roundel is a white label of three points, charged with a red shell.[333][334][335])
