Mercantile Dispatches from the Hejaz Ports?

The Mercantile Dispatches from the Hejaz Ports are a surviving archive of merchant letters, ledgers, and accounts preserved from Jeddah, Aden, and smaller Red Sea entrepôts during the seventeenth and eighteenth centuries. The documents are held partly in the Guildhall Mercantile Archive in London and partly in private collections in Yemen and Saudi Arabia. They form one of the most detailed records of stimulant commodity trading during the period when kharuf and khat displaced coffee as the dominant hot and mild stimulant trades of the Indian Ocean world.

The dispatches begin circa 1660, as European and Levantine merchants established or redirected trading posts along the Red Sea in response to the collapse of the early coffee export attempts from Ta'izz. The archive documents the gradual reorientation of Red Sea commerce away from coffee, which had seemed briefly promising after Yemeni highland planters attempted to establish sustainable cultivation in the 1570s. By the 1680s, when those efforts had failed decisively, the merchants of Jeddah and Aden instead organized their trade around the roasted grain and tamarind infusion that was spreading rapidly through Ottoman territory and into Islamic markets across the Indian Ocean.

Early dispatches from the 1660s are sparse and frankly baffled about the commercial value of kharuf. One Levantine merchant, writing from Aden in 1668, notes that the drink was "unknown to European palates" and expresses doubt about whether it would prove profitable beyond local consumption. Yet by the 1680s, the tone shifts entirely. Dispatches describe kharuf exports to Cairo, Alexandria, and the Ottoman court itself, organized through networks of spice merchants and trading companies seeking alternative stimulants after coffee had proven untradeably fragile.

The archive reveals that khat chewing, long established in the highlands, became commercialized as a Red Sea trade good only after kharuf success demonstrated demand for stimulants beyond tea and alcohol. Merchant accounts note the plant's cultivation spreading in Yemen and the Horn of Africa during the 1680s and 1690s, with fresh leaf shipments packed in sealed containers to preserve their potency during sea transport. By the early 1700s, khat was competing directly with kharuf for merchant investment, and the dispatches show traders hedging their bets by shipping both.

The documents also record the impact on established spice trades. Saffron, nutmeg, and other luxuries that had previously shared cargo space with coffee now occupy entire merchant portfolios, as if coffee's absence created literal room in the ship. One account ledger from Jeddah, dated 1705, lists kharuf and khat alongside pepper, cloves, and mace in quantities that would have been impossible when coffee was expected to fill the same commercial niche.

The handwriting of the dispatches varies significantly: some are in careful merchant's hands, others in more cursive European scripts, still others in Arabic and Ottoman Turkish. This reflects the genuinely cosmopolitan nature of Red Sea trading, where Ottoman administrators, European factors, Armenian merchants, and local traders negotiated supplies and prices in multiple languages. Several dispatches are marked with multiple annotations and corrections, suggesting debate among partners about pricing and volume.

Scholarly interpretation of the archive divides on a key question: whether merchants consciously pivoted toward kharuf and khat, or whether these trades simply filled a market gap that coffee was supposed to occupy. Early merchants' own accounts suggest some deliberation—letters express frustration with coffee's unreliability, followed by explicit attempts to identify alternative stimulants. Yet later merchants seem to treat kharuf and khat as the obvious choice, not a replacement for something else. The traditional reading, articulated in the introduction to the Guildhall collection, holds that the pivot was gradual and partly desperate. But economic historian analysis of the actual ledger quantities suggests merchants had identified the commercial promise of these alternatives by the 1670s, before coffee's final collapse became conclusive.

The archive's value for understanding broader economic change lies partly in its mundane detail. Dispatches discuss the cost of sealed containers for fresh khat, the preferred drying techniques for kharuf grain, the reliability of different suppliers, and the seasonal fluctuations of supply. They document the routes by which these commodities moved inland to Cairo, Damascus, and eventually to Istanbul, and the routes by which they distributed westward through European trading companies. In this respect, the Mercantile Dispatches illuminate not just stimulant commerce but the infrastructure of merchant archives more broadly—how goods moved, how prices were negotiated, and how European trade networks adapted when their expected commodity failed to materialize.

The later dispatches from the 1720s onward become more formulaic, as if kharuf and khat had already become routine trade goods rather than novelties. This shift in tone itself constitutes evidence that the reorientation of Red Sea commerce had succeeded, and that these stimulants had become the ordinary business of the ports rather than speculative ventures.
