Long before Mesopotamia emerged as the cradle of trade and record-keeping, the Iranian plateau had already defined economic organization, storage systems, documentation, and even methods of counting. Recent archaeological discoveries reveal that Iran was not a peripheral player but the beating heart of the earliest economic and administrative structures in the ancient world—a truth that history’s dust had long concealed.
Archaeologist Ruhollah Yousefi Zeshk emphasizes that sites such as Susa, Malyan, and Godin Tepe showcase Iran’s pivotal role in shaping these early systems. While classical trade and management tools are often linked to texts from 4th millennium BCE southern Mesopotamia, concrete evidence now indicates that these transformations occurred in Iran at least a millennium earlier.
Key sites like Tel-Bakun in the Marvdasht Plain near Persepolis and Godin Tepe provide unique insights into these ancient management systems. Excavations at Tel-Bakun have uncovered sealed clay locks—the earliest known devices for controlling and managing storerooms—predating similar developments in Mesopotamia by roughly a thousand years.
Archaeologist Ruhollah Yousefi Zeshk highlighted the close connection between trade and record-keeping, explaining that the development of storage systems made the documentation of transactions necessary. Although writing is traditionally credited to Mesopotamia, the earliest clay tokens, dating to around 3550 BCE, have been found at Godin Tepe in Iran. These artifacts represent the shared origins of later record-keeping systems in both Iran and Mesopotamia.
Yousefi Zeshk also pointed to a distinctive aspect of ancient Iranian trade: clay envelopes, which served as delivery notes or invoices and bore symbols representing the goods inside. Laboratory analyses of similar envelopes discovered at Hajibeyli in Turkey reveal that their clay originated from Susa, indicating that by around 3300 BCE, a sophisticated interregional trade network connected Susa and Anatolia.
He further emphasized the central role of sites such as Malyan and Susa. Recent interdisciplinary research shows that Malyan was not just a city but a seasonal commercial hub where nomads, pastoralists, and settled communities gathered to trade. Similarly, Susa functioned as a major regional market serving diverse ethnic and economic groups rather than a conventional city.
Comparing Iranian and Mesopotamian clay tokens, Yousefi Zeshk noted a key difference: in Mesopotamia, tokens were largely linked to temples and rarely recorded specific identities, while in Iran, each token clearly indicated the family, ethnic group, or merchant responsible for the transaction. This demonstrates the advanced economic and legal structures that existed in ancient Iran.
He also emphasized Iran’s central role in the history of mathematics, pointing out that the earliest decimal numbering systems—which underpin modern mathematical calculations—were first employed at sites such as Sialk, Godin Tepe, and Susa, whereas sexagesimal and duodecimal systems were used in other regions.
Concluding his remarks, the researcher stressed the need to revisit and recognize this rich civilizational heritage. Many chapters of Iran’s history, which represent achievements of global significance, have remained underappreciated and scarcely told. A large portion of the world’s early advancements originated in the Middle East, with a significant share occurring within Iran. He urged that these accomplishments be preserved, protected, and especially taught to younger generations, to strengthen the bond between Iran’s historical identity, knowledge, and future.
