hey i got sum info abt ...vanraj from the history of Gujrat
Chavada Dadda, the founder of Pratihara dynasty, established the Gurjar rule at Nandipur (Nandol). Dadda III wrested Broach from the Maitraks whose citadel had started shaking. In fact, there were three powerful dynasties which were ruling different parts of Gujarat: the Gurjars had their sway over the north, the Chalukyas ruled the south and the Maitraks were saddled in Saurashtra. The vaccum created by the fall of the Maitrak dynasty was filled up by the Pratiharas from the north and Rashtrakutas from the south. As vassals of the Valabhis (from the town of Valabhis or Vala, where the Guhilot ruled and is related to Bhavnagar Palitana and Lathi), the Chavadas held their sway over parts of north Gujarat. They assumed independent control after the fall of Valabhi. Vanraj, the most prominent of the eight Chavada kings, founded a new capital at Anhilpur Patan. he reconquered his father's lost territories and founded the Chavada dynasty which lasted a shade under a century. In the 14th century Mesaji ruler of this dynasty founded Mahasana in Gujrat.
