Chhota-Udepur, a princely state in western India, was formally known as Rewa Kantha. The rulers belong to the Chauhan dynasty and have descended from the legendary Prithviraj Chauhan, who once ruled Delhi, but was, through treachery, defeated in battle by a Muslim invader named Mohamed Ghori.

Thereafter, the descendants of Prithvirajsinh settled in various parts of India, including Gujarat, where they established the kingdom of Champaner–Pavagadh, now a world class Heritage site, over which they ruled between 1244 and 1484. Pavagadh was laid siege to by another Muslim invader Mohamed Begda for 12 years from 1472, and ultimately came into his hands in 1484, again through treachery.

Jaisinhdev, the ruler at that time, died defending his home. After the surrender of Pavagadh, Jaisinhdev’s two descendents migrated east to camp in a village called Hampeshwar on the banks of the river Narmada where nearby they built the fort of Mohangharh, the remains of which are visible even today.

The two brothers, Prithvirajsinh and Doongarsinh then conquered all the areas around them, after which, the elder brother Prithvirajsinh established the kingdom of Chhota–Udepur, on the banks of the river Orsang, while Doongarsinh went north to establish the kingdom of Devgadh-Baria, 50 kms away.
