The central part of the southern Caspian Sea region was densely inhabited during the third millennium B.C.E. From an archaeological perspective, it is important to understand when and how such lush environments supported large populations during the Bronze Age, and how these communities developed new socio-economic structures during the third and second millennia B.C.E. Ghal e-Ben is one of the key Bronze Age sites in the central part of Mazandaran Province, excavated in 2019. The site's occupation dates back to the Late Chalcolithic period (around 3200 B.C.E) and continued until the second half of the second millennium B.C.E (around 1500 B.C.E). Archaeological evidence from Ghal-e Ben indicates that during the Bronze Age, it was a fully sedentary agricultural settlement, inhabited by a large population whose economy was based on a combination of animal husbandry, including sheep, goat, pigs, and cattle, and large-scale farming. In a regional context, communities in the area became more complex during the second millennium B.C.E., as evidenced by the emergence of large cemeteries containing status goods, the development of new farming systems, and the establishment of long-distance trade networks. The cultivation of Chinese broomcorn and foxtail millet suggests the introduction of new crops and an evolving agricultural economy during this period. Our research program at the site of Ghal-e Ben not only provides a comprehensive chronological framework for the Bronze Age in both the southern and northern slopes of the Alborz Mountains, but also allows us to revise the chronology of several other sites that were previously dated using relative methods.
