Udasar
Udasar lies in the desert country associated with Bikaner, a city founded by Rao Bika in the late fifteenth century. Bika, a son of the ruler of Marwar, established a new Rathore kingdom among the chiefs of Jangladesh. Its capital grew amid a landscape of sand and scanty rain, where wells and tanks supported habitation. Forts and caravan routes linked Bikaner to the neighbouring desert states and the northern plains.
