The Prince Philip, Duke of Edinburgh (born Prince Philippos of Greece and Denmark, 10 June 1921) is the husband and consort of Queen Elizabeth II.

Originally a royal Prince of Greece and Denmark, Prince Philip renounced these titles shortly before his marriage. At the time of his engagement he was known as Lieutenant Philip Mountbatten. On 20 November 1947, he married Princess Elizabeth, the heiress presumptive to King George VI. Prince Philip is a member of the Danish-German House of Schleswig-Holstein-Sonderburg-Glücksburg, which includes the royal houses of Denmark and Norway and the deposed royal house of Greece.

The day before his marriage, King George VI granted him the style of His Royal Highness and, on the morning of the marriage, created him Duke of Edinburgh, Earl of Merioneth and Baron Greenwich. In 1957, Philip was created a Prince of the United Kingdom by Queen Elizabeth II. When he became a British subject Prince Philip took the surname Mountbatten, which is an anglicised version of his mother's German family name, Battenberg.

In addition to his royal duties, the Duke of Edinburgh is also the patron of many organisations, including The Duke of Edinburgh's Award and the World Wide Fund for Nature, and he is Chancellor of both the University of Edinburgh and the University of Cambridge. In particular, he has devoted himself to raising public awareness of the relationship of humanity with the environment since visiting the Southern Antarctic Islands in 1956, and has published and spoken widely for half a century on this subject. See Wikiquote excerpts from these speeches.

The prince continues to fulfil his public duties as a member of the British Royal Family, and is an established public figure in the United Kingdom and in the Commonwealth Realms. He has gained a reputation for making controversial remarks, some of which have been interpreted as being racist, particularly when meeting the British public or on state visits to other countries.
