Djenné-Djenno: West Africa's Oldest Known City on the Niger

Djenné-Djenno (also written Jenné-Jeno, “ancient Djenné”) is an archaeological site in the Inland Niger Delta of Mali, settled around 250 BC and occupied until about AD 1400. Excavations from 1977 showed that it grew into a large, densely populated town with long-distance trade, iron-working and its own city wall. Because it flourished long before Arab merchants reached West Africa, Djenné-Djenno transformed how historians understand the origins of African cities.

Setting: the Inland Niger Delta

The Inland Niger Delta is a vast floodplain in central Mali where the Niger and Bani rivers spread out across the land each rainy season. When the waters recede they leave rich soil, fish-filled channels and pasture. This seasonal landscape supported farmers, fishers and herders, who could exchange their products with one another.

Djenné-Djenno lies about 3 km southeast of the modern town of Djenné, close to the Bani River. Today it is a large mound, or tell, of about 33 hectares, built up by centuries of mud-brick houses, rubbish and burials. Smaller mounds surround it, including Hambarketolo, which was linked to the main site by a causeway.

Discovery and excavation

Local people had always known the mound as the place of “old Djenné”. Its age and scale were revealed by the American archaeologists Susan Keech McIntosh and Roderick J. McIntosh, who excavated there in 1977 and again in 1981, working with Malian colleagues.

Their trenches cut through several metres of deposits. Radiocarbon dates showed that the earliest occupation went back to about the 3rd century BC. The results, published in the late 1970s and 1980s, surprised many scholars, because they contradicted widely held assumptions about West Africa’s past.

How the city grew

The first settlers already used iron and made pottery. They grew African rice (Oryza glaberrima), a crop domesticated in West Africa, and they fished and kept cattle. Iron ore and stone are not found on the floodplain, so from the beginning these materials had to be brought in from outside.

Over the following centuries the settlement expanded steadily. By the late 1st millennium AD the town and its neighbouring mounds formed a large urban cluster. A mud-brick wall about 2 km long was built around the main mound, probably around AD 800, although its exact date is debated.

The peak of the town came around AD 800–1000. Estimates of the population at that time vary widely, from several thousand to more than 20,000 for the town and its satellites. All such figures are based on the size of the mounds and the density of houses, so they should be treated as rough ranges.

A different kind of city

Djenné-Djenno did not look like the cities of ancient Egypt or Mesopotamia. Archaeologists have found no palace, no large temple and no clear sign of a ruling elite with monumental tombs. Instead, the town appears to have been part of a cluster of settlements, each perhaps home to different groups such as smiths, potters, fishers or farmers.

Roderick McIntosh described this pattern as a “clustered city”, where many specialised communities lived side by side and depended on one another. He argued that authority was shared among groups rather than concentrated in a single ruler, a model sometimes described with the term heterarchy. Not all scholars accept every part of this interpretation, but it has influenced debates about early cities worldwide.

Trade before the camel caravans

Objects from far away reached Djenné-Djenno early in its history. Copper, which does not occur locally, appears in the first millennium AD and must have come from sources in the Sahara or beyond. Glass beads found at the site point to long-distance exchange networks that eventually connected to the Mediterranean world and the Indian Ocean.

The town traded local products such as rice, fish and dried foods for iron, stone, copper and salt. Its position made it a natural link between the farmers of the floodplain and the peoples of the Sahara edge. In later centuries this regional network fed into the wider trans-Saharan gold and salt trade, which helped empires such as Ghana grow rich.

Art and the terracotta tradition

The Inland Niger Delta is famous for its terracotta sculptures of humans and animals, mostly dated to around AD 1100–1400. Some were found by archaeologists in their original setting at Djenné-Djenno and nearby sites, showing that they belonged to local religious or household practices.

From the 1970s onwards a large international art market developed for these figures. Illegal digging destroyed many sites in the region before Mali and other countries strengthened protections. The loss of context means that the meaning of many surviving terracottas is now hard to recover. The tradition is much later than the Nok terracottas of Nigeria, but both show the depth of West African sculpture.

Decline and abandonment

From about AD 1200 the population of Djenné-Djenno seems to have fallen, and by around 1400 the site was abandoned. At the same time, the town of modern Djenné grew nearby and became a major Islamic centre and trading city. Local tradition holds that a ruler of Djenné converted to Islam in the 13th century, and the town’s famous mosque dates from this later period.

Historians have suggested several reasons for the move: the spread of Islam, changes in trade routes, political shifts or environmental pressures. The evidence does not allow a single clear answer. What is clear is that urban life in the region did not end, but shifted a few kilometres away.

Myths and facts

Myth: West African towns were founded by traders from North Africa. For much of the 20th century, many writers assumed that cities such as Djenné, Timbuktu and Gao arose only after Muslim merchants opened regular caravan routes across the Sahara. Djenné-Djenno shows that a substantial town already existed in the region centuries earlier, and that outside trade built on existing local networks rather than creating them.

Myth: Djenné-Djenno was the capital of an empire. There is no evidence that the town ruled a large state. It was an important regional centre, but its power seems to have rested on trade, crafts and cooperation between neighbouring communities.

Fact: it was not the only early town. Later surveys in the Inland Niger Delta and the Middle Niger have found many other large mounds. Djenné-Djenno is the best studied, but it was part of a wider urban landscape.

Timeline

• c. 250 BC: First settlement on the site, by iron-using farmers and fishers.
• c. AD 1–400: Steady growth; long-distance exchange in materials such as stone and iron.
• c. AD 800: Probable construction of the town wall around the main mound.
• c. AD 800–1000: Peak extent of the town and its cluster of satellite settlements.
• c. AD 1100–1400: Period of the best-known Inland Niger Delta terracottas.
• c. AD 1400: Djenné-Djenno is abandoned as modern Djenné rises nearby.
• 1977 and 1981: Excavations by Susan Keech McIntosh and Roderick J. McIntosh.
• 1988: The site is included in the UNESCO World Heritage Site Old Towns of Djenné.

Why it matters

Before Djenné-Djenno was excavated, many scholars believed that cities in West Africa were created by North African and Arab traders who arrived after the 8th century AD. The site showed that a large town with crafts, trade and a city wall had grown up locally many centuries earlier. It placed West Africa firmly among the regions of the world where urban life developed independently, and it remains a key reference for the history of the Great Mosque of Djenné and the wider Niger region.
