The State-Insured Silk Road: Seljuk Caravanserais
During the 13th century, the Seljuk Sultanate of Rum engineered one of the ancient world's most sophisticated logistics networks to secure trade. They constructed a network of fortified stone roadhouses called
caravanserais, spaced precisely 30 kilometers apartโthe exact distance a camel caravan could travel in a single day. According to modern archaeological surveys by the

Turkish Ministry of Culture, over 100 of these structures dotted the Anatolian landscape, offering merchants free lodging, food, and veterinary care for up to three days. Crucially, the Seljuk state acted as a pioneer in commercial insurance, fully compensating merchants for any goods lost to bandits along these monitored routes, which dramatically minimized the risk of long-distance trade.
Why today: The dramatic plunge in Strait of Hormuz shipping traffic this weekend, dropping to just 12 transiting vessels, highlights how the physical security and state-backing of global trade corridors remain as critical to the modern economy as they were to medieval empires.
