Shāh is a royal title meaning 'king' in Persian. Though chiefly associated with the monarchs of Iran, it was also used to refer to the leaders of numerous Persianate societies, such as the Ottoman Empire, the Khanate of Bukhara and the Emirate of Bukhara, the Mughal Empire, the Bengal Sultanate, and various Afghan dynasties, as well as among Gurkhas.
