Four thousand years ago, Assyrian merchants from the city of Ashur established a network of trading colonies across Anatolia — creating what may be the world's first documented international business network, documented in an archive of over twenty-three thousand clay tablets from the site of Kanesh in modern Turkey.
The ancient site of Kültepe in modern Turkey — ancient Kanesh — has yielded over 23,000 clay tablets documenting a remarkable chapter in ancient commerce. Between roughly 1950 and 1750 BCE, Assyrian merchants from Ashur maintained a trading colony (karum) at Kanesh from which they conducted long-distance trade with Anatolian cities. The tablets — business letters, contracts, accounts, and personal correspondence — provide the most detailed picture of ancient commercial practice available from any period. They are the ancient equivalent of a company's complete business records.

The Old Assyrian merchants carried tin and textiles westward from Ashur to Anatolia, exchanging them for silver and gold carried back east. The tin — for bronze production — may have originated in Afghanistan, representing one end of a supply chain of extraordinary geographic reach. The textiles were high-quality woven goods produced by Assyrian women. The correspondence includes detailed instructions from merchants to their wives about producing specific textile types and weights for particular Anatolian markets — a remarkably modern division of domestic production and commercial sales.
What makes the Kanesh archive extraordinary beyond its commercial content is its humanity. Letters between merchants and their wives discuss business affairs, family matters, and personal concerns across hundreds of miles. Merchants complain about unreliable agents; wives complain about husbands' neglect of family duties; business partners dispute accounts. The human experience of long-distance trade — the loneliness, the disputes, the anxieties about credit and reputation — is vividly present in these four-thousand-year-old business letters. Ea-Nasir and Nanni would have recognised every complaint.
