The Anatolian Tin & Obsidian Highway (Kültepe-Kanesh Karum)
The Bronze Age network linking Assur, Kültepe-Kanesh, Hattusha, and Troy with donkey caravans carrying tin and cuneiform tablets
📦Key Commodities
🐎Primary Transport
Black donkey pack caravans (thousands recorded in clay tablets) traveling in organized trading companies (ellatum)
Spanning 2,100 kilometers across 7 major stations, this overland route was sustained by strategic oasis wells, stone-paved causeways, imperial customs houses, and fortified mountain garrisons.
📜Expedition Overview
Operating four thousand years ago, the Old Assyrian trade network represented the world’s first thoroughly documented private capitalistic venture. Merchant families based in Assur financed caravans of hundreds of black donkeys laden with tin (imported from the east) and fine Babylonian woolen textiles, marching over 1,200 kilometers across the Taurus Mountains to Kültepe (ancient Kanesh in Cappadocia). In exchange, they exported Anatolian silver and gold back to Mesopotamia, documenting every transaction, customs tariff, and family dispute on clay tablets wrapped in clay envelopes.
🔬Archaeological Evidence & Excavations
Over 23,000 cuneiform clay tablets discovered in the merchant houses of Kültepe-Kanesh (UNESCO Memory of the World) detail the prices of tin, profit margins, caravan loss insurance, and family correspondence, creating an unmatched micro-history of Middle Bronze Age daily commerce.

“To Imdi-ilum speak: thus says your sister Tar’am-Kubi. You wrote to me saying: "The house is empty; send me woolen textiles with the next caravan!" But donkeys are scarce, and the price of tin in Assur has risen by two shekels!”
