Abstract The present paper examines the socio-economic conditions for the ascendancy of the Zoroastrian community in Western India between the 18th and 19th centuries. This study reinforces the well-established thesis on the role played by the Parsis in the development of capitalism in India. What distinguishes it from other narratives is the periodization of this development and the consideration of Parsi agency in the Western Indian Ocean region and East Africa, especially Mozambique. The cooperation of the Parsis with the European trade companies and private European traders as of the mid-17th century—most notably, their links to the English East India Company, which boosted the Zoroastrian communities of northwestern India—is investigated. I try to show how the Parsis, who had been predominantly peasants, farmers and artisans from the 10th to 17th centuries, increasingly embarked upon trade, moneylending, brokerage and production. Because of their accumulated wealth, their numbers as well as their influence augmented throughout the 18th and 19th centuries.
