Prince Philip has lived quite a life during his 99 years on Earth.
From joining the British army as a teen, where he served during WWII, to falling in love with widowed wife Queen Elizabeth II and going on to share four children and 10 grandchildren with Her Majesty, Philip's life was anything but mundane.
The Duke of Edinburgh also lived an active and healthy life, as he was an avid polo player; however, his final months consisted of a lengthy 28-day hospital stay and heart procedure. Despite the "successful" surgery last month, news of his tragic death followed soon thereafter.
Buckingham Palace confirmed that the Queen's husband passed away at their Windsor home on Friday, April 9. "It is with deep sorrow that Her Majesty The Queen announces the death of her beloved husband, His Royal Highness The Prince Philip, Duke of Edinburgh," the Queen's statement read. "The Royal Family join with people around the world in mourning his loss."

One year after Philip and Elizabeth tied the knot, they welcomed their first son, Prince Charles, who was heir to the throne.

During their stay from 1949-1951, Elizabeth announced she was pregnant with daughter Princess Anne — whom they welcomed in August 1950.
