King-Emperors and Queen-Empresses sometimes have used the style Imperial and Royal Majesty (e.g., The Empress Frederick's style Her Imperial and Royal Majesty The German Empress and Queen of Prussia).
The reigning British monarchs from 1876 to 1948[1] had the style Imperial Majesty as Emperors of India.
However, this style was only sometimes used in relation to the imperial title as Emperor or Empress and never as King or Queen.
[2] The last Shah of Iran, Mohammad Reza Pahlavi, also used the style of "Imperial Majesty".
Today, the style is assumed by Farah Pahlavi, the exiled Shahbanu of Iran.
