The Princess Elizabeth marries Lieutenant Philip Mountbatten, who becomes the Duke of Edinburgh, at Westminster Abbey in London.

Elizabeth II was Queen of the United Kingdom and other Commonwealth realms from 6 February 1952 until her death. She had been queen regnant of 32 sovereign states during her lifetime and was the monarch of 15 realms at her death. Her reign of 70 years and 214 days is the longest of any British monarch, the second-longest of any sovereign state, and the longest of any queen regnant in history.

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.

Duke of Edinburgh, named after the capital city of Scotland, Edinburgh, is a substantive title that has been created four times since 1726 for members of the British royal family. It does not include any territorial landholdings and does not produce any revenue for the title-holder.

Westminster Abbey, formally titled the Collegiate Church of Saint Peter at Westminster, is an Anglican church in the City of Westminster, London, England. Since 1066, it has been the location of the coronations of 40 English and British monarchs and a burial site for 18 English, Scottish, and British monarchs. At least 16 royal weddings have taken place at the abbey since 1100.
