Birth order and full names
Prince Harry, born Henry Charles Albert David on 31 August 1984, is the younger son of Charles III (then Prince of Wales) and Diana, Princess of Wales. His older brother is Prince William, full name William Arthur Philip Louis, born 21 June 1982. William is first in line to the throne; Harry is second at birth, then third after William’s children. Both were born at St Mary’s Hospital, London, and hold the titles prince of the United Kingdom by birth. Their names and dates are documented in royal biographies and parliamentary succession records.
House of Windsor lineage and title history
As sons of the heir apparent, both boys received princely titles and the style Royal Highness at birth. After Diana’s death in 1997, their father became King, making William the heir apparent and Harry the second in line. The Windsor house framework assigns regnal numbers based on the sovereign line; William as the elder carries future regnal styling that will affect how Harry’s line is referenced. Key dates include the 1982 birth of William and the 1984 birth of Harry, both registered in Westminster and reflected in official birth indexes.
Official roles and public duties
William performs constitutional and representational duties as the heir, focusing on public service, the armed forces, and the devolved nations. Harry, as a working royal for many years, engaged in military service and veterans’ work before stepping back to pursue commercial and philanthropic activities. Both have given speeches on mental health, yet their institutional roles differ: William is styled Prince of Wales and carries national ceremonial responsibilities; Harry remains a senior royal with charitable patronage while also operating as a private citizen under the Sussex designation.
Succession position and protocol
Under the Perth Agreement and current law, succession is determined by birth order and legitimacy. William precedes Harry; Harry precedes William’s children. This hierarchy affects titles, security, and access to certain audiences. Protocol typically calls for William to attend state occasions and Commonwealth engagements, while Harry represents the monarchy on veterans and youth initiatives. In practice, their visibility varies by cause, region, and diplomatic schedule.

Private lives and media scrutiny
Both brothers have faced intense media attention. William’s courtship and marriage to Catherine Middleton were broadly framed as a modern fairy tale, while Harry’s marriage to Meghan Markle and subsequent decision to step back from royal duties triggered global discussion. The brothers’ public statements on mental health, press ethics, and institutional reform reflect distinct experiences shaped by birth order, timing, and personal choices. Verification of personal milestones relies on palace announcements, biographies, and reputable news reporting.
Philanthropy, commerce, and future outlook
William’s philanthropy centers on early childhood, mental health, and environmental work through royal and corporate roles. Harry and Meghan launched Sussex Royal (now Archewell), focusing on equity, crisis response, and veterans. Commercially, Harry engages in media deals and advocacy; William balances royal patronage with business collaborations through the Royal Foundation. Going forward, their paths are likely to diverge further, with William assuming greater constitutional duties and Harry continuing independent projects, each influencing public perceptions of the monarchy’s future structure.
