It is a branch of the Johiya Jats. Kulhari Jats ruled in the Marwar area in the 11th to 12th century. Bahipal was their king and Kot-Marot was their capital. There was a fort also at Kot-Marot. Bahipal had a war with the subedar of Hisar in which he lost his kingdom.
Bahipal moved to Kathod and established a new kingdom there. Kathod is about 22 km from Ajmer. The descendants of Bahipal constructed a fort at Koliya. The Raja of Koyal pattan arrested the Kulahari Jats. Myth is that their Kuldevi Pada got them released. After that the Kulhari Jats made Didwana as their capital. They established at Didwana statues of Bahipal and the Kuldevi Pada.
Another theory is that there was a king in Haryana who had three sons. One was Khichar, another was Mahla & the third one was Kulhari. These sons came to Rajasthan. Mahlas settled in a place called Bhalaria in Jhunjhunu. From there they migrated to other places in Rajathan. As a matter of fact Mahla, Kulhari & Khichars are considered brothers & don’t marry in their gotras.
