Royal Highness (abbreviation HRH) is a style (His Royal Highness or Her Royal Highness); plural Royal Highnesses (abbreviation TRH, Their Royal Highnesses). It appears in front of the names of some members of some royal families but is not used for Kings or Queens who are styled Majesty.

The style Royal Highness ranks below Imperial Highness, but above Grand Ducal Highness, Highness, Serene Highness and some other styles.

By the 17th century, all local rulers in Italy adopted the style Highness, that was once used by kings and emperors only. According to Denis Diderot's Encyclopédie, the style of Royal Highness was created on the insistence of Archduke Ferdinand of Austria, Infante of Spain, a younger son of King Philip III of Spain. The Archduke was travelling through Italy on his way to the Low Countries and, upon meeting Victor Amadeus I, Duke of Savoy, refused to address him as Highness unless the Duke addressed him as Royal Highness. Thus, the first use of the style Royal Highness was recorded in 1633. Gaston, Duke of Orléans, younger son of King Henry IV of France, encountered the style in Brussels and assumed it himself. His children later used the style, considering it their prerogative as grandchildren of France.

Elizabeth II (Elizabeth Alexandra Mary; born 21 April 1926) is the constitutional monarch of 16 sovereign states known as the Commonwealth realms, and head of the 54-member Commonwealth of Nations. She is also head of state of the Crown Dependencies.

Elizabeth was born in London, and educated privately at home. Her father acceded to the throne as George VI in 1936 on the abdication of his brother Edward VIII. She began to undertake public duties during the Second World War, in which she served in the Auxiliary Territorial Service. On the death of her father in 1952, she became Head of the Commonwealth and queen regnant of seven independent Commonwealth countries: the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan, and Ceylon. Her coronation service in 1953 was the first to be televised. Between 1956 and 1992, the number of her realms varied as territories gained independence and some realms became republics. Today, in addition to the first four aforementioned countries, Elizabeth is Queen of Jamaica, Barbados, the Bahamas, Grenada, Papua New Guinea, the Solomon Islands, Tuvalu, Saint Lucia, Saint Vincent and the Grenadines, Belize, Antigua and Barbuda, and Saint Kitts and Nevis.
