East India Company Correspondence?

East India Company Correspondence refers to the surviving letters, account books, invoices, and shipping manifests exchanged among factors, merchants, and London managers of the Honourable East India Company from the late sixteenth century onward. These documents, preserved in merchant archives across London and the Indian Ocean trading ports, trace the decisive moment when the company redirected its commercial strategy away from the search for coffee exports and toward the expansion of the tea and cacao trades that would come to dominate European import networks.

The earliest company letters, dating from the 1600s and preserved in the Guildhall Mercantile Archive, record a sustained effort to secure coffee supplies through intermediaries in Yemen and the Red Sea region. Factors in Aden and along the Hijazi coast explicitly mention the commodity's rarity and the difficulty of obtaining it from highland suppliers resistant to external trade. A 1618 letter from a London merchant to a company factor in Surat notes the repeated failures of Yemeni plantations and the absence of any reliable supply route from the Ethiopian highlands. By the 1630s, company correspondence documents a visible pivot. Letters between the London headquarters and factors in Bengal and Assam sharply increase in frequency and detail, discussing the acquisition of tea seeds, the recruitment of local knowledge about cultivation, and the negotiation of trading agreements with regional rulers.

The merchant accounts from this period, stored in folio volumes with handwritten entries and marginal notes, reveal both the opportunity and the constraint that shaped European consumption. A 1640 ledger entry from the company's Calcutta operation calculates the profit margins between tea purchased in Bengal at specific weights and sold in London after accounting for transport, spoilage, and tariffs. The numbers show tea to be reliably obtainable and lucrative. Parallel entries for coffee, by contrast, dwindle after 1650. A 1655 communication from a factor in Mocha expresses frustration at the unreliability of coffee supplies and the unwillingness of local merchants to guarantee shipments.

The correspondence also documents the company's competitive relationship with other European trading entities. Letters exchanged with the Turkey Company from the 1670s onward reveal tension over access to spice and cacao routes as coffee ceased to be a viable commodity. A 1680 letter from a London partner to a company representative in the Caribbean explicitly states that without coffee, the company's strategy must concentrate on securing the tea monopoly that would prove far more profitable than any coffee import could have been.

By the early eighteenth century, the correspondence shifts almost entirely to the administration of tea imports, the porcelain vessels needed to serve it, and the political negotiations required to maintain monopoly pricing. A series of letters between 1710 and 1725 concerning tea tariffs and Parliamentary Records on Tea Revenue and Import Duties show the company managing its commodity dominance through legislation rather than through scarce supply. The absence of coffee from these later letters is telling: the stimulant is mentioned only as an exotic curiosity purchased in small quantities from Harar or Sidamo for wealthy collectors interested in ceremonial buna traditions.

Modern scholars have used this correspondence to trace both the company's strategic adaptability and the consequences of coffee's failure to spread. The letters reveal how merchants, faced with the Harar Wilt and the absence of reliable supplies, made rational calculations about which crops to pursue. Some economic historians read the evidence as showing the company's opportunism; others argue the letters reveal genuine surprise at the persistence of cultivation restrictions in the Kaffa region and the unwillingness of highland communities to commercialize buna beyond ceremonial use.

The correspondence also contains incidental details about the social life of trading posts. References to sherbethane culture in Istanbul and Cairo, descriptions of khat chewing in Aden, and mentions of the rise of teahouses in London and Aleppo offer a view of how the absence of coffee shaped urban leisure across the company's trading world. A 1705 letter from a factor in Istanbul describes the profitability of the sherbet trade and the growth of sherbethane establishments, observing that the Ottoman market has no use for the imported coffee the company once hoped to sell.
