Shahanshah

Shah (/ˈʃɑː/; Persian: شاه‎, king) is a title given to the kings and lords of Iran and India. It was continuously used in Persia and Greater Iran. In India, it was used by Mughal rulers. The word derives from the Old Iranian, Avestan xšaΘra, "power" and "command", corresponding to Sanskrit (Ancient Indian) kshatriya, "warrior". The full, Old Persian title of the Achaemenid rulers of the First Persian Empire was XšāyaΘiya XšāyaΘiyānām, "King of Kings"."
