A city older than the caravans
For many years, writers often assumed that West African towns appeared only after Arab traders crossed the Sahara by camel, and that urban life had been brought from outside. Jenne-Jeno is one of the main reasons that view is no longer widely held. The site lies on the floodplain of the inland Niger delta in present-day Mali, about three kilometres from the modern town of Djenné. Excavations show a settlement there from roughly the third century BCE, well before any regular trans-Saharan trade is documented.
The name is often rendered as “ancient Djenné”. The site was investigated in the late 1970s, with major excavations in 1977 and 1981 led by the archaeologists Susan and Roderick McIntosh, and later work has added to their findings.
How it grew
The inland delta is a flat region where the Niger and Bani rivers flood each year, creating a rich mosaic of fishing grounds, grazing land and farmland. The first settlers at Jenne-Jeno appear to have lived by fishing, herding cattle and sheep or goats, and growing crops. Evidence suggests that African rice, a species domesticated in West Africa, was among the crops grown nearby, along with millet, though how early and how important rice was remains a matter for ongoing study.
Iron was in use from an early stage, and pottery in a variety of forms was made in large amounts. Around the first few centuries CE the settlement expanded, and it reached its largest size, probably in the later first millennium CE, when it covered a few dozen hectares. A mud-brick wall of considerable length was eventually built around the town. Because mud brick weathers quickly, the structures were built up in layers over time, forming a tall mound (a tell), which is why tell stratigraphy matters here. Researchers could read the town’s history in the layers of the mound.
A cluster of settlements
Jenne-Jeno was not alone. Survey of the surrounding floodplain found dozens of smaller mounds within a few kilometres, many occupied at the same time as the main town. The researchers argued that the settlements formed a connected urban complex of specialised communities. Some villages may have focused on metalworking, others on fishing or pottery, and they traded with one another.
This led to a notable idea. The McIntoshes used the term heterarchy for a society organised in several overlapping networks of power rather than as a single pyramid with a king at the top. Jenne-Jeno showed no clear sign of a palace or monumental tombs, and no sign of a centralised ruler. Its size and density nonetheless matched what archaeologists would call a city. How far that interpretation holds is debated, because unexcavated areas and the limits of surface survey leave room for other readings. As a comparison, many of the earliest urban societies in Mesopotamia are associated with temples and rulers, and Jenne-Jeno suggests that this was not the only path.
Trade and exchange
Although Jenne-Jeno did not depend on the desert caravans to exist, it was not isolated. Finds from the site include items from outside the delta, such as copper and glass beads, and stone that was not available locally. The delta lay at a natural meeting place between the Sahara and the wetter lands to the south. Goods such as grain, dried fish and iron may have moved north in exchange for salt and copper, a pattern that later fed into the networks of the Ghana empire and the Mali Empire. Traders on the Niger travelled by canoe, and river transport was probably crucial for the delta economy, much as Nile river boats were for Egypt.
As Islam and the trans-Saharan trade grew in importance after about 800 CE, towns along the Niger developed new ties to the north. The exact role of Jenne-Jeno in the gold trade is uncertain, as the site is not named clearly in early Arabic sources.
Decline and the move to Djenné
By about the 14th century, the site had been largely abandoned, though dating the end of its occupation precisely is difficult. Several explanations have been suggested, including a drier climate affecting the floods, political changes, or a shift of population to nearby Djenné, which became a major centre of trade and Islamic learning. A researcher cannot always distinguish among these causes using the material left behind.
Terracotta figures of kneeling, seated and mounted people, often described as Djenné terracottas, are associated with the later period and have been the target of looting. Because looted pieces lack a recorded find-spot, they tell archaeologists very little, and they are one reason the site’s protection has been a concern. Jenne-Jeno was added to the UNESCO World Heritage list in 1988, together with the old town of Djenné.
Why it matters
Jenne-Jeno matters less for monuments than for what it shows about method and assumptions. Careful use of radiocarbon dating and the study of changes in pottery styles allowed the town’s long timeline to be built from ordinary rubbish and building layers. Its history does not fit older models in which every early city needed a ruler or foreign inspiration. Other settlements in the region, including sites in the delta and along the Niger, suggest Jenne-Jeno was part of a broader tradition, though our knowledge of that tradition is still developing.
