Were there some "Jat" clans that took to trading and become a "Baniya" in the long run?
In ancient times, trading was done by two kind of people:
1. One who were travelling from place to place.
2. Others who were settled at a single place for a considerable amount of time.
The travelling people traded goods and other related stuff that was often brought from different lands and kingdoms, whereas local traders traded in local goods.
Therefore it seems, that local traders were different from the travelling people, local people might have been deep rooted in south Indian cultures, rather than nomadic and horse man culture.
The concept of horse man culture does not only belong to Jats as in present day scenario, rather to many different kinds of tribes, people, ethnicity who were doing different kinds of work and trade these people were different from"Baniyas".
Jats due to their Scythian origins were one of the main core group of travelling, migrating, settling people throughout northwest of ancient Bharat, central asia, middle east and other parts of the globe.
