Marwaris are the most famous and widespread trade community in India. That community includes business magnates like Birla and also the small traders found all over the cities and towns of India. It was during the colonial rule that the Marwaris became so successful in their trade. They took advantage of the opportunities offered by the colonial rule in cities like Calcutta. To engage in trade and money-lending business, they spread across India. Like the Nagarathars, they were able to make use of extensive trade chains and acquire the confidence of the business world.

Towards the end of the colonial rule, and even after independence, the Marwaris continue to march forward successfully. Many Marwari families became modem industrialists. Even now amongst all communities, Marwari community has the biggest share of Indian industries. This story of the Marwaris shows the importance of social background in economic processes.
