On the balcony were, among others, Charles' mother Queen Elizabeth II, her mother the Queen Mother Elizabeth and Charles' father Prince Philip.
The tradition of the royal wedding party appearing on the Buckingham Palace balcony after the ceremony began with Charles' ancestress, Queen Victoria, and was continued by Charles' parents, Elizabeth and Philip on the balcony, and by Charles' son and his new bride in 2011, William and Catherine on the balcony.
