Rawal (also spelled Raval) or Raol originally is a variation of the Hindi princely ruler title Ra(d)ja(h) (literally "king") used in some princely states in Rajputana and Western India (notably Gujarat), and is now also used as a caste designation or surname by several communities in Southern Asia.
Notable (but non-salute) states using this title for their ruling prince were, both under the colonial Mahi Kantha Agency (in the third -high- of seven classes of states) and in present Gujarat :
the Raol of Malpur
the Raol of Mansa
This 'Western' equivalent of the higher (gradually deflated) Hindi title Maharaja (literally 'great king') was notably used by three salute states in Rajputana (presently in Rajasthan), all entitled to a (high-ranking) Hereditary gun salute of 15-guns :
the Maharawal of Jaisalmer
the Maharawal of Banswara
the Maharawal of Dungarpur
and one in Gujarat, entitled to a (rather low-ranking) Hereditary salute of 9-guns (11-guns personal) :
the Maharaol (or Maharawal) of Bari(y)a
