Before Prince William and Kate were even born, the world celebrated another "royal wedding" -- the union of Queen Elizabeth II and Prince Philip, the Duke of Edinburgh.
Tuesday marks the royal couple's 65th, or Blue Sapphire, wedding anniversary. The Queen and her husband (who was born Prince Philip of Greece) are the first British royals to celebrate this milestone, so we wish them a heartfelt congratulations!
Elizabeth and Philip, who began exchanging letters in 1939 when Elizabeth was 13 years old and Philip was 18, were married at Westminster Abbey in 1947 in front of 2,000 guests. Another 200 million people listened to the radio broadcast of the nuptials and thousands lined the streets of London to watch the spectacle.
Elizabeth's gown was designed by Norman Hartnell and featured a long train with rose, wheat and star appliques. The ceremony began at 11:30 a.m. with a procession of eight bridesmaids and two pages, and after the service, which was conducted by the Dean of Westminster, the couple traveled by horse-drawn carriage to Buckingham Palace for a celebratory wave to the crowds.
The newlyweds received 2,500 wedding gifts and honeymooned at Birkhall on the Balmoral Estate in Scotland.
