As heir to the British throne and the first-born child of King Charles and his late wife Diana, Princess of Wales, Prince William was destined to be in the public eye from the moment he arrived into the world.
The Prince of Wales, a title he was given in September 2022 by Charles upon the late Queen Elizabeth II's death, was born on 21 June 1982.
We've followed his life from his early years at Kensington Palace, schooling at prestigious Eton College, and finally his years at the University of St Andrews, where he met his future wife Princess Kate. The couple married in 2011 and now William, 41, is a devoted family man to Prince George, Princess Charlotte, and Prince Louis.
