About the Shah surname. Indian (Gujarat, Rajasthan, MP, UP): Hindu (Bania, Vania) and Jain name, from Gujarati sah 'merchant' (from Sanskrit sadhu 'honest', 'good'). This name was originally Sah; it appears to have been altered under the influence of the Persian word for 'king'. Shah or its variants Sah, Shaha, Sahu or Sha is a common Gujarati last name. A large fraction of all Jain, vaishnavas, especially from Gujarat and southern Rajasthan, have the last name Shah. Sometimes it is mistakenly thought that it is derived from the Persian Shah meaning King. Actually it is of Indian origin[1]. It is derived from Sanskrit Sadhu (meaning gentleman) and Prakrit Sahu, while the actual spelling Shah in Western culture was popularized by the title of the former Persian King.
