Nomadic pastoralists kept on moving from place to place with their animals. They lived on milk and other pastoral products. They also exchanged items like wool, ghee, etc. with settled agriculturists for grain, cloth, utensils, and other products. They bought and sold these goods as they moved from one place to another, transporting them on their animals. The Banjaras were trader-nomads who bought grain where it was cheaply available and carried it to places where it was dearer. From there, they again reloaded their oxen with anything that could be profitably sold in other places. Thus, they played an important role in connecting India to the outside world. Many pastoral tribes reared and sold animals, such as cattle and horses, to the wealthy people. Different castes of petty pedlars traveled from village to village. They made and sold wares like ropes, reeds, etc. Sometimes mendicants acted as wandering merchants. There were also castes of entertainers who earned their living by performing in different towns and villages.
