Prince William of Wales KG FRS (William Arthur Philip Louis; born 21 June 1982) is the elder son of Charles, Prince of Wales, and Diana, Princess of Wales, and grandson of Queen Elizabeth II and Prince Philip, Duke of Edinburgh. He is second in the line of succession, behind his father, to the thrones of 16 independent states, although he is resident in and more directly involved with the United Kingdom, the oldest of these realms. William began to accompany his parents on official visits at an early age; his first overseas royal tour was with his parents to Australia and New Zealand in 1983,[22] a decision made by the Princess of Wales that was considered to be unconventional; not only was William so young, but both the first and second in line for the throne would be travelling together.[11] However, he accompanied either both parents or his father on subsequent tours, and, upon graduation from university, began to undertake duties of his own, as well as obtaining experience in the private workforce when he worked with land management at Chatsworth House and interned at HSBC. Following his parents' examples, William took interest in various causes from a relatively early age. The late Princess of Wales' work with HIV/AIDS aid and prevention, and the Prince of Wales' work with the natural environment and the inner-city disadvantaged, directed William into those areas. He also showed a desire to focus on the needy in Africa, sometimes working with his brother's charity, Sentebale.On 23 January 2009, it emerged that Prince William had written the foreword to a book for the first time.[47] The cover of Home from War, the autobiography of a soldier from the Prince's regiment who was seriously wounded in a Taliban ambush, notes his contribution. During his years in university, William participated in typical university life, going to bars and socialising with his friends; of himself he said: "I'm not a party animal, despite what some people might think."[11] Like his father before him, William's private life became the subject of tabloid speculation and gossip, especially around his relationship with Kate Middleton, who had been one of William's university flatmates and whom William began dating in 2003. Middleton attended the Prince's passing-out parade at Sandhurst, marking the first high-profile event that she attended as William's guest. The relationship between Prince William and Middleton was followed so closely that bookmakers took bets on the possibility of a Royal Wedding and the retail chain Woolworths produced memorabilia bearing the likenesses of the two.[56] Media attention became so intense that William had to make a specific request to the paparazzi that they keep their distance from Middleton and him. In March 2007, Middleton complained of media harassment by the Daily Mirror.[56] It was reported in April 2007 that the couple had split,[56][57] though in June, Middleton attended a party at Lulworth Army Barracks as the guest of Prince William,[58] in July she attended the Concert for Diana, which had been organised by Princes William and Harry.[59] In August, she accompanied William on holiday in the island of Des Roches in the Seychelles, and in October she joined Prince Charles and Prince Harry for a shooting party at Balmoral. In June 2008, along with the Royal Family, Middleton attended William's investiture into the Order of the Garter.
