Queen Elizabeth II and Prince Philip watch the troops ride past outside Buckingham Palace following the Queen's Birthday Parade, 'Trooping the Colour' at Horse Guards Parade in London on June 16, 2012. The ceremony of Trooping the Colour is believed to have first been performed during the reign of King Charles II. In 1748, it was decided that the parade would be used to mark the official birthday of the Sovereign. More than 600 guardsmen and cavalry make up the parade, a celebration of the Sovereign's official birthday, although the Queen's actual birthday is on 21 April

The 91-year-old Duke of Edinburgh returned to daily life as a royal on Saturday, taking in a military flyover in his first public appearance since he went to the hospital with a bladder infection weeks ago. Prince Philip, the queen’s husband, had weathered earlier health scares, but this one caused him to miss some of the festivities for Queen Elizabeth’s Diamond Jubilee. The event Saturday marked the queen’s birthday. At the time of Philip’s hospitalization, performer Elton John joked that the prince was only feigning illness to get out of having to attend a planned concert for the jubilee celebrations, saying, “He hates pop music—anything to get out of a pop concert.”
