History

Shahr-e Sukhteh emerged in the Sistan basin around 3200 BC. Within centuries it had grown into one of the largest cities in the ancient world, a major node connecting Mesopotamia, the Indus Valley, and the Gulf in a web of long-distance trade. Its workshops processed raw materials imported from hundreds of kilometres away: lapis lazuli from Badakhshan in Afghanistan, carnelian from Sindh, obsidian from Anatolia or the Caucasus, copper from Oman. The manufactured objects — beads, vessels, seals, figurines — were exported across a vast network.

Three massive fires, at different points in the site’s occupation history, destroyed large portions of the city and left layers of charred debris that give it its modern name. Rather than causing permanent abandonment, the fires were followed by reconstruction; only the final phase, ending around 1800 BC, was not rebuilt. The cause of permanent abandonment is debated: the Helmand River shifted course repeatedly across the Sistan basin, and climatic drying may have reduced the agricultural base. Systematic excavations began in 1967 under Italian and Iranian archaeologists, notably Maurizio Tosi of IsMEO, continuing into the 21st century.

The discoveries overturned assumptions about the precocity of civilisation in the Iranian plateau and its connections to Mesopotamia and the Indus Valley. The Helmand Culture now emerges as a fourth major axis of Bronze Age urban civilisation alongside Mesopotamia, Egypt, and the Indus Valley — one that traded with all three simultaneously.
