Emperor/Empress of India (Shahanshah-e-Hind in Hindustani) was used as a title by the last Mughal emperor Bahadur Shah II, and also by the British monarchs during the rule of British India.
Sometimes, the term "Emperor of India" is also used to refer to Indian emperors such as Ashoka the Great of the Maurya Dynasty[1] and Emperor Akbar of the Mughal empire. However, they did not claim this title for themselves.
