Prince Philip, Duke of Edinburgh, was the husband of Queen Elizabeth II. As such, he was the consort of the British monarch from his wife's accession on 6 February 1952 until his death in 2021, making him the longest-serving royal consort in history.

Prince Philip of Greece and Denmark was born on 10 June 1921 on the dining room table in Mon Repos, a villa on the Greek island of Corfu. He was the only son and fifth and final child of Prince Andrew of Greece and Denmark and his wife, Princess Alice of Battenberg. Philip's father was the fourth son of King George I and Queen Olga of Greece and his mother was the eldest child of Louis Mountbatten, 1st Marquess of Milford Haven, and Victoria Mountbatten, Marchioness of Milford Haven (formerly Prince Louis of Battenberg and Princess Victoria of Hesse and by Rhine). A member of the House of Glücksburg, Philip was a prince of both Greece and Denmark by virtue of his patrilineal descent from George I of Greece and George's father, Christian IX of Denmark; he was from birth in the line of succession to both thrones. Philip's four elder sisters were Margarita, Theodora, Cecilie, and Sophie. He was baptised in the Greek Orthodox rite at St. George's Church in the Old Fortress in Corfu. His godparents were his paternal grandmother, his cousin Crown Prince George of Greece, his uncle Lord Louis Mountbatten, and the mayor of Corfu, Alexandros Kokotos.
