Vanthali officially Vamansthali Now is a small town in Junagadh district in the Indian State of Gujarat. There are traces that this place was inhabited many many centuries back. It was called "Vamanasthali" or "wamansthali" in ancient days.

After the destruction of Maitraka dynasty of Saurashtra, Sorath area became independent. During this time the Vamansthali area was ruled by Walaram, a Chavda Rajput king. Raja Wala Ram had no sons, and the question arose as to who should succeed him after his death. It happened that among the Hindu tribes which had migrated Southward before the encroachments of the Mahomedans was that of the Samas, who settled at Saminagar (now Nagar Thatha), in Sindh. Wala Ram's sister had been married to the chief of the Samma tribe, and her son, Ra Chuda, was selected to follow his uncle at Wamansthali.

Accordingly, at Wala Ram's death, in about A.D. 875, Ra Chuda founded the Chudasama dynasty, adding the name of his father's tribe to his own name. The Chudasama quickly became very powerful, and from an inscription at Dhandhusar we learn that the rulers of all neighbouring countries regarded them as paramount. The dynasty continued to hold sway from 875 A.D. to 1473 A.D. nearly six hundred years. Having capital Vamansthali and Junagadh alternatively.
