Dear student,
In early times, large villages with varied commercial and social activities came to be viewed as small developing towns, where people from different regions flocked in to sell their items in the local market called mandi. Large scale trading took place in these towns where in craftsmen, oil pressers, pottery makers, jewellery makers, vegetable vendors came to sell their produce. Taxes were levied on the traders and articles traded by the zamindar.
Regards.
