Traditionally the Rajputs, Jats, Meenas, Gurjars, Bhils, Rajpurohit, Charans, Yadavs, Bishnois, Sermals, PhulMali (Saini) and other tribes made a great contribution in building the state of Rajasthan. All these tribes suffered great difficulties in protecting their culture and the land. Millions of them were killed trying to protect their land. A number of Gurjars had been exterminated in Bhinmal and Ajmer areas fighting with the invaders. Bhils once ruled Kota. Meenas were rulers of Bundi and the Dhundhar region.
