Early Life and Greek Danish Surname
Birth Name and Royal Lineage
Prince Philip was born Prince Philip of Greece and Denmark on 10 June 1921. As a member of both the Greek and Danish royal houses, his legal surname at birth reflected those dynastic origins. In European royalty, birth names often carry the historical houses of the parents, which in his case was Schleswig-Holstein-Sonderburg-Glücksburg, a branch of the House of Oldenburg.
Family Background and Titles
His father, Prince Andrew of Greece, and his mother, Princess Alice of Battenberg, provided Philip the surnames of both nations. The Greek and Danish royal families had intertwined histories, and this lineage shaped his early identity before he renounced his Greek and Danish titles to marry Princess Elizabeth.

After serving in the Royal Navy and before his marriage to Princess Elizabeth, Philip adopted the anglicized version of his mother’s maiden name, Mountbatten. This change aligned with his new life in the United Kingdom and reflected his commitment to Britain, while still honoring his family heritage.
Royal House Distinction
Although his surname became Mountbatten in everyday use, he remained a prince of Greece and Denmark by birth. The adoption of Mountbatten was a practical step for integration into British public life and for the naming conventions of future royal descendants.
