Prince Philip, the husband of Queen Elizabeth II, died Friday aged 99. “His Royal Highness passed away peacefully this morning at Windsor Castle,” the royal family announced. Philip was hospitalized in February after “feeling unwell” and was treated for an infection and a preexisting heart condition. He was released a month later after undergoing a heart procedure. “We mourn today with Her Majesty The Queen, we offer our condolences to her and to all her family, and we give thanks, as a nation and a Kingdom, for the extraordinary life and work of Prince Philip, Duke of Edinburgh,” Prime Minister Boris Johnson said in a statement. During the coronavirus pandemic, Philip and Elizabeth had been staying at Windsor Castle, west of London. Both the duke and the queen were the world’s longest-reigning monarch. Philip was born June 10, 1921, on the Greek island of Corfu as the youngest child and only son of Prince Andrew of Greece and Denmark and Princess Alice of Battenberg. At age 7 in 1928, Philip was sent to school in England. As a teenager, Philip joined the Royal Navy and went on to serve in World War II, including participating in the battles of Cape Matapan and Crete and the invasion of Sicily.
In 1947, the 26-year-old Philip married his third cousin, Princess Elizabeth, 21. Elizabeth was formally crowned queen in 1953. In the decades following his marriage to the queen, the Duke of Edinburgh had taken up more than 22,000 solo engagements, 637 overseas visits, delivered an estimated 5,493 speeches and worked as a patron to almost 800 organizations. The couple celebrated their 70th wedding anniversary in November 2017.
