Titles

The day before the wedding, King George VI bestowed the style of Royal Highness on Philip and, on the morning of the wedding, 20 November 1947, he was made the Duke of Edinburgh, Earl of Merioneth, and Baron Greenwich of Greenwich in the County of London. Consequently, being already a Knight of the Garter, between 19 and 20 November 1947 he bore the unusual style His Royal Highness Sir Philip Mountbatten and is so described in the Letters Patent of 20 November 1947.
