The Sephardic Refuge: How Ottoman Sanctuaries Remade Levantine Trade
Following the Alhambra Decree in 1492, which ordered the expulsion of practicing Jews from the Iberian Peninsula, an estimated 100,000 to 200,000 Sephardic refugees were cast into exile across the Mediterranean basin. Recognizing the commercial and administrative acumen of the diaspora, Ottoman Sultan Bayezid II dispatched imperial naval vessels under Admiral Kemal Reis to evacuate stranded families from

Spanish ports, formally welcoming an estimated 40,000 exiles to settle in Salonica, Constantinople, and Smyrna. The arriving artisans and merchants revolutionized the imperial economy, establishing the empireโs first commercial printing presses in 1493, modernizing foundry casting for bronze artillery, and constructing sophisticated international mercantile networks connecting Venice to Aleppo. Within two generations, Salonica transformed from a quiet Aegean port into the foremost textile manufacturing hub of the eastern Mediterranean, illustrating how imperial sanctuaries converted displaced diasporas into engines of regional economic supremacy.
Why today: As fresh military closures and diplomatic impasses shutter transit arteries across the

West Bank and the Persian Gulf this morning, the Sephardic migration demonstrates how regional stability and trade routes have historically hinged on the movement and legal sanctuary of displaced peoples.
