Why “kingdom” is only part of the story
West Africa is a large region, stretching from the Sahara’s southern edge to the Atlantic coast and the Gulf of Guinea. Over roughly two thousand years it produced cities with no central ruler, priest-led polities, trading empires and centralised monarchies. The word “kingdom” fits some of these well and others poorly, so it helps to keep the differences in view.
The evidence is also uneven. Written sources for the early periods are mostly outside accounts, written in Arabic by travellers, geographers and scholars who often relied on second-hand reports. From the inside, much of what is known comes from oral tradition: king lists, genealogies and epics preserved by specialists such as the griots of the Mande-speaking peoples. Archaeology fills gaps but has been done unevenly, and many sites have been excavated only in part or looted. Dates before about the 11th century CE are therefore usually approximate, and many are debated.
Early foundations
Several developments predate the large states. The Nok culture of central Nigeria, active in roughly the first millennium BCE and into the early centuries CE, is known for Nok terracotta sculpture and for early evidence of iron smelting. Whether ironworking arrived from elsewhere or arose independently in West Africa is still discussed, and the wider story of ironworking spread across the continent is not settled.
Further west, the Jenne-Jeno city on the inland Niger delta grew from about the third century BCE into a substantial settlement with many satellite mounds, apparently without a king or a strong central state. It is a useful reminder that urban life in the region did not depend on the later Saharan trade.
Ghana, Mali and Songhai
The first of the large Sahelian states in the written record is the kingdom the sources call Ghana, the title of its ruler, with Wagadu as the Soninke name. It was known by the late 8th century as a land of gold, and the Andalusian geographer al-Bakri described its court in 1068. Its wealth rested on the Wagadu gold trade, in which gold from the south was exchanged for Saharan salt and goods carried by camel caravan. The modern country of Ghana took the name in 1957 but lies hundreds of kilometres to the south-east of the old kingdom.
Ghana declined over the 11th to 13th centuries, and the Mali Empire rose from the Mande heartland. Its founder is remembered in the Epic of Sunjata, and the date usually given for his decisive victory is around 1235. Mali’s best-known ruler, Mansa Musa, made a pilgrimage to Mecca in 1324-25 that was long remembered in Egypt and across the Mediterranean world. Timbuktu and Djenné became centres of trade and Islamic learning.
Songhai, centred on Gao on the Niger bend, overtook Mali in the 15th century, most strongly under Sunni Ali (reigned from about 1464) and then Askia Muhammad, whose reign began in 1493. A Moroccan army defeated Songhai at Tondibi in 1591, and the empire fragmented afterwards. Our main sources for these centuries include the Timbuktu chronicles, written in the 17th century, which are valuable but were composed well after many events they describe.
The central Sudan and the forest belt
Around Lake Chad, Kanem and later Bornu formed one of the longest-lived states in the region, with roots reaching back to roughly the 9th century CE and a long record of contact across the Sahara. To the west of it, the Hausa city-states such as Kano and Katsina were trading towns more than a single empire.
South of the savanna, the forest belt supported other traditions. The bronzes of Igbo-Ukwu, dated by radiocarbon dating to about the 9th or 10th century CE, show that Igbo-speaking communities had highly skilled metalworkers long before any European contact. The area is also associated with Nri ritual authority, in which priest-kings held influence through religion rather than armies. Ife, in Yoruba country, is known for naturalistic metal and terracotta heads, and Oyo later became a powerful Yoruba state with a large cavalry.
The Kingdom of Benin, ruled by the Edo oba, rose in the forest of what is now southern Nigeria. Tradition places a major period of expansion under Oba Ewuare in the 15th century. Benin is well known for its brass plaques and cast heads. Many were taken by a British expedition in 1897 and are now held in museums around the world, where their return is the subject of ongoing negotiation.
The Akan states and Dahomey
The later kingdoms of the forest and coast were shaped by the Atlantic trade. The Ashanti state, which emerged around 1700 under Osei Tutu, drew on Akan gold-working and on a political union symbolised by the Ashanti Golden Stool. Dahomey, in what is now Benin Republic, rose in the 17th century and became a centralised military state. Both took part in the Atlantic slave trade, which reshaped the political and human landscape of the region and cannot be left out of any honest account of these kingdoms.
Reading the sources
A few habits help when reading about West African history:
- Treat oral tradition as evidence about how a society remembers itself. It often preserves genuine events, but its dates and sequences need checking against other sources.
- Remember that Arabic travellers described what they were told or saw on a short visit, and had their own assumptions.
- Be wary of claims that a kingdom was ancient simply because it was famous. Many of the best-documented states are medieval or early modern.
- Notice what is missing. Cities with little monumental stone, like those built in mud brick, leave less obvious traces than Egyptian or Mediterranean sites.
The trans-Saharan routes, moreover, did not appear overnight. Earlier Saharan peoples such as the Garamantes, with their foggara tunnels bringing water to desert oases, show that contact across the desert has a long history. The caravans of the medieval period were one chapter of it, comparable in importance to the Silk Road trade routes in linking distant economies, though on a smaller scale.
Where to go next
The articles in this section take up individual cases in more depth. They include the rise of Ghana, the early urban settlements of the Niger, the Nok figures, the Nri kingdom and the Ashanti, as well as the great states of eastern and southern Africa that lie outside this region but share many of the same questions about evidence.
