Shah

Shah (; , , ) is a royal title that was historically used by the leading figures of Iranian monarchies. It was also used by a variety of Persianate societies, such as the Ottoman Empire, the Kazakh Khanate, the Khanate of Bukhara, the Emirate of Bukhara, the Mughal Empire, the Bengal Sultanate, historical Afghan dynasties, and among Gurkhas. Rather than regarding himself as simply a king of the concurrent dynasty (i.e. European-style monarchies), each Iranian ruler regarded himself as the Shahanshah (, ) or Padishah (, ) in the sense of a continuation of the original Persian Empire.
