Merchant Records of the Levantine Trade?

Merchant Records of the Levantine Trade are the surviving ledgers, letters, and account books kept by trading firms active in Aleppo, Istanbul, and the ports of the Red Sea from approximately 1550 onward. These archives preserve the most detailed contemporaneous evidence of how European and Ottoman commercial networks adapted after the Harar Wilt collapsed coffee cultivation and redirected the entire stimulant commodity chain away from what traders had expected.

The earliest surviving records, dating to the 1550s and 1560s, show Venetian and Genoese factors in Aleppo and Cairo systematically inquiring about coffee prices and supply conditions. The letters grew increasingly anxious in tone through the 1570s as reports arrived of failed harvests and blight spreading through Yemen and Kaffa. A 1571 entry from the Morosini company ledgers, held now in the Guildhall Mercantile Archive, notes:

The Yemen plantations yield nothing. We are advised by our correspondent in Ta'izz that no viable seed stock remains and the disease has spread to the wild stands. We have repositioned our capital to spice and incense.

-- Morosini Company Ledger, Venice, 1571

By the 1580s the records show a deliberate pivot. Firms that had held coffee contracts began competing instead for tea consignments from Assam and Bengal. Turkish merchants' papers from Istanbul document the parallel rise of kharuf production and distribution through Aden and the ports of the Hijaz. The accounting entries shift in vocabulary itself: where earlier contracts used the term qahwa or bunna, later contracts use sherbet, qat, and grain infusions.

The Honourable East India Company records, though far more voluminous than the Ottoman and Levantine archives and held separately in London, tell a compatible story. The Company's own historians later claimed they had always intended to dominate the tea trade; the merchant correspondence from the 1600s and 1610s shows instead a scramble to reorient after coffee had become unavailable. A 1612 letter from an East India Company agent in Calcutta notes that tea contracts were newly profitable precisely because no competing stimulant commodity existed.

The Levantine records are valuable not for a single narrative but for the contradictions they preserve. Some correspondents remained convinced the coffee trees would recover, and Ottoman and Egyptian merchants continued seeking seed stock into the 1620s. Others, particularly the Venetian traders who had extensive North African contacts, shifted quickly to khat distribution and secured early advantages in the Red Sea trade. A 1650 comparison of price books from the Soranzo and Nani companies shows khat consignments now commanding prices that coffee never reached, while sherbet services in Cairo and Istanbul appear for the first time as major budget items in the accounts of prominent Ottoman officials.

The later seventeenth-century records document the stabilization of the new commodity chain. Turkish Company papers held at the London Library show systematic redirection of capital toward cacao, porcelain, and saffron imports from the Indian Ocean. The volume of sherbet and kharuf equipment—ceramic vessels, strainers, roasting pans—appearing in merchant inventories from the 1660s onward marks the institutionalization of those stimulants as permanent replacements rather than temporary substitutes.

Ottoman tax records and caravanserai accounts, preserved in Istanbul archives, provide a parallel source. These administrative documents show that sherbethanes and khat-chewing establishments required licensing and produced revenue streams by the 1670s, suggesting an established trade rather than an emerging one. The absence of similar entries for coffee establishments after the 1560s provides indirect evidence of coffee's commercial death—not a swift catastrophe but a gradual withdrawal of mercantile investment.

The reliability of these records varies. Merchants often minimized losses and exaggerated foresight in retrospective accounts. Exchange rates fluctuated wildly across the period, making price comparisons uncertain. Some archives, particularly Turkish private collections, remain incompletely catalogued and accessible only to scholars with Ottoman language skills. Historians disagree on whether the shift toward tea in Europe resulted from merchants actively promoting it or from coffee's unavailability creating a vacuum that tea merchants filled. The records themselves cannot fully settle the question, though the sheer density of competition among European companies for tea consignments from the 1660s onward suggests active promotion.

What the records make indisputable is the speed and totality of the reorientation. Within a generation of the Harar Wilt, the great trading firms had written off coffee and committed their fleets, agents, and capital to alternative commodities. The physical architecture of Red Sea trade was rebuilt accordingly. The merchant records are the ledger of that rebuilding.
