Prince Philip, Duke of Edinburgh, Earl of Merioneth and Baron Greenwich, was born Prince of Greece and Denmark in Corfu on 10 June 1921. He was the only son of Prince Andrew of Greece, grandson of King Christian IX of Denmark and great-great-grandson of Queen Victoria.
His mother was Princess Alice of Battenberg, the eldest child of Prince Louis of Battenberg. During the First World War the family changed its name to Mountbatten, and Prince Philip adopted the name Mountbatten when he became a naturalised British subject and renounced his Royal title in 1947.
The Duke turned 18 in 1939, and was on active service in the Royal Navy throughout the Second World War. His first naval appointment was as a midshipman to HMS Ramillies, which escorted the first contingents of the Allied Expeditionary Force from Australia to Egypt. Towards the end of the war he served on the destroyer HMS Whelp, and was present in Tokyo Bay for the Japanese surrender on 2 September 1945. Following the war and his marriage, he ceased active naval appointments, but was promoted to Admiral of the Fleet in 1953, and was made Field Marshal of the Army and Marshal of the Royal Air Force; he holds 42 Service appointments in total.
The Duke married the future Queen Elizabeth in Westminster Abbey on 20 November 1947. The Queen and Prince Philip share Queen Victoria as great-great-grandmother, and are also related through the Duke's paternal grandfather, King George I of Greece, who was Queen Alexandra's brother. The Royal couple had four children: Prince Charles, now Prince of Wales, Heir apparent to the throne, born in 1948; his sister, Princess Anne, now The Princess Royal, in 1950; Prince Andrew in 1960; and Prince Edward, in 1964. Prince Andrew and Prince Edward were the first children to be born to a reigning monarch since Queen Victoria had her family.
The Duke is only the fifth consort to a reigning queen in British history. He has accompanied the Queen on all of her overseas tours, and fulfils a range of public duties. He is keenly interested in environmental issues, science and technology, and is a prolific writer on environmental, technological, equestrian and animal subjects. He founded The Duke of Edinburgh's Award Scheme and International Award to introduce young people to new experiences, including physical, skills-based and community challenges. Some 74 other prizes and medals are associated with The Duke of Edinburgh.
