From Consular Office to Trade Corridor: The Diplomatic Networks and Commercial Roles of Levantine Merchants in Ottoman Salonica and Smyrna (1780-1860)

This article examines how Levantine merchants in Ottoman Salonica and Smyrna navigated and shaped both diplomatic networks and commercial circuits between 1780 and 1860. Building on recent scholarship in commercial diplomacy and network analysis, it argues that the liberalization of the Levant Company (1744; 1753 Acts) fostered a hybrid class of “broker-diplomats” who leveraged consular commissions to secure firmans, tariff advantages, and cargo quotas while simultaneously expanding independent trade in opium, textiles, and other high-value commodities (Serdaroğlu, 2019, pp. 406–407; Schulz, 2014, pp. 120–121). The study reconstructs the Smyrna-Salonica corridor as a contiguous economic space through prosopographical network analysis of key figures (Webster, Wedderburn, Peach, Hague) and GIS mapping of maritime and caravan routes. Archival diplomatic correspondence (The National Archives FO 78) and factory account ledgers further reveal how gift-giving and consular privileges underpinned commercial expansion (Vlami, 2014, pp. 10–12; Demiryürek, 2023, pp. 113–114). Theoretically anchored in commercial diplomacy and Actor–Network Theory, our findings illuminate the entanglement of formal and informal networks that underwrote British commercial dominance in the Ottoman Levant.
