Prince William, Duke of Cambridge – Biography, Age, Family

Jack Arthur Murray • 2026-06-07 • Reviewed by Ethan Collins

Prince William, the Prince of Wales, is the elder son of King Charles III and the late Diana, Princess of Wales. As heir apparent to the British throne, he balances centuries-old royal tradition with a modern public role, focusing on mental health, environmental advocacy, and supporting the monarch.

Born on 21 June 1982 at St Mary’s Hospital in London, William Arthur Philip Louis was the first heir to the throne born to a Prince and Princess of Wales since 1894. He was raised with a keen awareness of his future responsibilities, shaped by both the privilege and the intense media scrutiny that accompanied his mother’s public life.

Today, William is 43 years old (as of June 2025) and lives at Kensington Palace with his wife, Catherine, Princess of Wales, and their three children. His official duties, charitable projects, and the gradual transition of responsibilities from his father define his present and future as the next king.

What Is the Current Status of Prince William’s Relationship with Prince Harry?

The relationship between Prince William and his younger brother Prince Harry has been widely reported as strained. Harry, born 15 September 1984, and his wife Meghan Markle stepped back from senior royal duties in 2020 and moved to California. According to reporting from multiple outlets, including Fox News, the rift deepened after the publication of Harry’s memoir Spare in 2023.

In May 2025, Harry publicly expressed a desire for reconciliation. However, family sources told Fox News that William’s demeanor had shifted toward “indifference,” leaving little room for a quick repair. The palace has not issued any official statements confirming private conversations. No verified details about the brothers’ current contact exist in the public domain.

What Is Known for Certain

Prince William and Prince Harry are not working members of the same royal team. Harry and Meghan are no longer senior royals and do not carry out official duties. The two brothers have not been photographed together publicly since 2022.

What Is the Deeper Context Behind Prince William’s Role?

William’s transition from Duke of Cambridge to Prince of Wales marked a significant evolution. The title had not been used since his father, King Charles III, became king. With it came the Duchy of Cornwall, a private estate that funds his public and charitable work. He has steadily increased his profile on global issues, most notably through the Earthshot Prize, an initiative aimed at finding solutions to environmental challenges.

His mother’s legacy continues to inform his priorities. William has spoken openly about the importance of mental health, co-founding the Heads Together campaign with Catherine and Harry. In 2025, he became the patron of We Are Farming Minds, an organisation supporting mental health in the agricultural community.

The broader 2025 news cycle has placed William in a supporting role as King Charles undergoes cancer treatment. According to BBC Royal Coverage, William has taken on additional engagements, preparing for the day he will become king while managing the ongoing public interest in the rift with his brother.
