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."

Philip and Elizabeth, who first met in 1939 when the Queen was 13 and Philip was five years her senior, announced they were engaged in 1947.
On November 20, 1947, the royals married at London’s Westminster Abbey.
In order to marry Elizabeth, Philip had to give up his Greek and Danish titles, as well as any claim to foreign thrones.
One year after Philip and Elizabeth tied the knot, they welcomed their first son, Prince Charles, who was heir to the throne. The couple then resided in Malta, where Philip was based in the Navy, for two years. During their stay from 1949-1951, Elizabeth announced she was pregnant with daughter Princess Anne — whom they welcomed in August 1950.
