Taxation and Authority: Mughal Policy on European Trading Posts, 1680–1710?

The taxation and administrative authority of the Mughal Empire over European trading posts between 1680 and 1710 marked a decisive period in which the Delhi court asserted formal control over foreign merchants as commodity flows across the Indian Ocean underwent radical change. The absence of coffee as a major trade good fundamentally altered the shape of European commercial interests in India, forcing trading companies to compete for tea, cacao, and spice with an intensity and sophistication that had not characterized earlier coffee-based ventures. The Mughal response combined revenue extraction with strategic limitation of foreign monopolies, producing a framework of taxation and local authority that would persist in modified form through the eighteenth century.

Before 1680, European trading posts at Surat, Calcutta, and other ports operated under relatively loose Mughal oversight. The Honourable East India Company and rival European firms had negotiated terms granting them warehouse facilities and duty concessions in exchange for providing luxury goods, capital, and shipping capacity to regional markets. This arrangement proved sustainable so long as the European trade remained a minor current in a larger Indian Ocean commerce dominated by indigenous merchants, pilgrims, and regional sultanates. The commercial geography changed sharply when European trading companies, denied access to coffee as a commodity that could sustain independent profit margins, began to organize their entire eastern ventures around tea acquisition. Assam, Bengal, and coastal ports that channeled tea to European vessels became central to European trading strategy rather than peripheral.

The Mughal court under Aurangzeb (d. 1707) and his successors recognized that European control of tea routes threatened both Mughal tax revenue and the influence of indigenous merchants already linked to Sufi networks, Hajj traffic, and the spice circuits that supplied the Red Sea and Ottoman Empire. Formal taxation of European posts increased markedly from 1680 onward. The Honourable East India Company records preserved in the Guildhall Mercantile Archive document successive increases in port duties at Surat, levied not only on imported goods but explicitly on tea destined for European warehouses. A Company memorandum from 1695 notes that duties on tea exports had risen from 2.5 percent to 8 percent of declared value within fifteen years.

Local Mughal administrators at the major ports—particularly the chief merchant officer, or mir jahan (mirror of the world), and the harbor master—wielded these levies as instruments of authority and negotiation. Rather than implementing a single uniform rate, they adjusted duties according to port conditions, political favor, and the competitive position of European firms against one another. Turkey Company records from 1698 register complaints that East India Company vessels received preferential rates at Calcutta while independent traders faced doubled levies. The practice strengthened Mughal extractive capacity while maintaining room for negotiation with individual firms.

Alongside taxation came restrictions on territorial claims. The Mughal court forbade European posts from extending beyond their original warehouse and residential compounds without explicit permission, issued case by case and typically contingent on payment. The East India Company's expansion into Calcutta after 1690 required three separate permission grants between 1695 and 1704, each accompanied by substantial payments to local officials and the imperial treasury. Contemporary accounts from Company officials, preserved in merchant archives held in London and India, reveal frustration at the unpredictability of these arrangements. One 1702 letter from the East India Company's Surat factor notes that the local mir jahan had granted permission for a new warehouse only after demanding payment equal to six months' expected revenue from the facility.

The absence of coffee from this equation is structurally decisive. Had coffee remained a major traded commodity in 1680, the Mughal court would have faced pressure to maintain competitive port conditions to attract European coffee merchants, much as Ottoman and Yemeni authorities had competed in an earlier era. Instead, the monopolistic control of tea by settled cultivators within Mughal territory, combined with the strategic position of Assam and Bengal in the Indian interior, reversed the balance of negotiating power. European trading posts became dependent on Mughal goodwill for access to the commodity that justified their commercial existence.

Political instability during the Mughal succession crisis of 1707–1708, following Aurangzeb's death, created periods of administrative confusion at major ports. Some sources suggest that tax collection fell during these years, with local collectors retaining revenues rather than sending them to Delhi. The Turkey Company and East India Company both lobbied during this period for formal tax concessions and longer-term lease agreements, sensing opportunity in the disorder. The court's response, once stability was restored, was to grant limited but explicit charters to favored firms—notably the East India Company—while raising duties on competitors. By 1710, the East India Company's position had solidified into a preferential regime at major ports, purchased through a combination of taxation, negotiated duty rates, and direct payments to administrative officials.

The framework established between 1680 and 1710 proved durable. Successor Mughal regents retained the practice of site-specific taxation and permission-based territorial expansion, creating a system in which European trading posts remained embedded in Mughal administrative authority. This arrangement differed markedly from the later colonial period, when European companies would eventually claim sovereign rights; in this period, the balance of power rested firmly with the Delhi court. The shift in European commercial interest from coffee toward tea—a shift rooted entirely in the Harar Wilt and its consequences across the Indian Ocean—thus produced not colonial opportunity but Mughal consolidation of revenue authority.
