The Empire of Ghana (Wagadu)
The earliest of West Africa's great trading empires, whose Soninke kings grew rich taxing the trans-Saharan trade in gold and salt and whose name was borrowed by the modern Republic of Ghana at independence.
Events
Soninke Clans Unite Under the Kings of Wagadu
By the 8th century AD, Soninke-speaking clans of the western Sahel had united under a dynasty known as Ghana or Wagadu, with its center at Kumbi Saleh in modern southeastern Mauritania. The king held both political and religious authority, presiding over a court that Arab chroniclers later described as one of the wealthiest in the known world.
Location: Sahel, West Africa
The Gold-Salt Trade Across the Sahara
The empire's wealth rested on its position astride the trans-Saharan trade: gold mined at the Bambuk and later Bure fields to the south was exchanged, in a silent-barter system described by Arab geographers, for salt caravaned from Saharan mines. Ghana's kings taxed every caravan that passed, financing an army that later Arab sources numbered in the tens of thousands. The trade also carried Islam, which took root in the merchant quarter of Kumbi Saleh.

Ibn Hawqal Describes Ghana's Wealth
The geographer Ibn Hawqal, writing around 972, reported the title of the Ghana emperor as "the richest king in the world" on account of his gold. His account and other Arabic sources introduced the empire to the wider Islamic world, where West Africa became known as "the land of gold."

Al-Bakri's Account of the Court of Ghana
The Andalusian geographer Abu Ubayd al-Bakri, relying on reports from Muslim traders, wrote the most detailed surviving description of the empire: a king with an army he claimed numbered 200,000, a court of splendor at Kumbi Saleh, and the Islamic faith of the trading town alongside the traditional religion of the royal town. His work remains the principal written source on the empire, which itself left no written records.

The Almoravid Capture of Kumbi Saleh
The Almoravids, a Berber reformist movement from the Sahara, seized Kumbi Saleh in 1076. Arabic sources describe a sack of the capital; modern historians debate whether this was a genuine conquest or a more limited raid, and whether Almoravid influence was as decisive as older narratives claimed. The episode marks the beginning of the empire's decline, as vassal peoples — including the Sosso under the Kante clan — began to break away.

The Sosso Take Kumbi Saleh
Around 1203 the Sosso king Sumanguru Kanté, a leader remembered in Mande oral tradition as a sorcerer-king, captured Kumbi Saleh and took over the remnants of Ghana's hegemony. The Soninke dynasty's authority was reduced to its heartland, and regional power shifted to the Sosso kingdom.

The Battle of Kirina and the Rise of Mali
At Kirina around 1235, Sundiata Keita of the Mandinka defeated Sumanguru Kanté, breaking Sosso power. By about 1240 the former lands of Ghana had been absorbed into the rising Mali Empire, which inherited and expanded the gold-salt trade system Ghana had built. The Epic of Sundiata, preserved in oral tradition, frames this transition.

Excavations at Kumbi Saleh
French archaeologists began excavating Kumbi Saleh in 1913, uncovering a stone-built town with multi-story houses, mosques, and trade goods from across the Sahara — physical confirmation of the Arab chroniclers' accounts. The site is on Mauritania's UNESCO World Heritage tentative list, and modern Ghana, independent in 1957, deliberately adopted the name of the ancient empire it never territorially included.
