At the Queen's Side: Prince Philip Through the Years
Prince Philip, confidante and companion of more than 70 years to Queen Elizabeth, is the longest-serving consort of any British monarch.
Queen Elizabeth II's husband, Prince Philip, will stand down from royal duties later this year, British officials announced on May 4.
A month ahead of his 96th birthday, he has decided it is time for a rest.
Here's a look back at the life of the man who has stood by the queen's side for more than 70 years.

Born in Corfu, Greece in 1921, Prince Philip was a member of the Greek and Danish royal families. A year later, his uncle was forced to abdicate as king, leading the family to flee to France, where this picture was taken when he was attending the MacJannet American School in the Paris suburb of St. Cloud.
