According to a Jain account, the last of the Parmar line became a convert to the Jainism, and resigned his chiefdom to his sister's son, the Chauhan Saregogji Ratansingji of Nadol, an ancestor of the Rana of Vav, in 1275 (Samvat 1331). Others say that the Chauhan killed his maternal uncle and usurped the chiefdom. The Chauhans, with the title of Rana, ruled at Tharad for about six generations, till, in the reign of Rana Punjaji, they were attacked by the Muslims, their capital stormed, and their chief slain. Another account says that the Chauhan Rajputs were driven out by the Rathods of Jodhpur, who were succeeded by the Muslims in fifteenth century.
