While the transatlantic slave trade was largely driven and industrialized by European powers, it would not have functioned at the scale it did without the active participation of African kingdoms and merchants, who supplied captives — often prisoners of war, debtors, or people targeted through raids — to European traders in exchange for goods like guns, alcohol, cloth, and luxury items.
The Arab or Islamic slave trade (also called the trans-Saharan or Red Sea trade) was older, beginning around the 8th century, and it continued alongside the Atlantic trade for centuries. It also involved African intermediaries and Muslim merchants.
Here’s a list of Ghanaian kingdoms and states that were involved in the slave trade, either as sellers, intermediaries, or participants in slave raiding.
Kingdom/State | Role in Slave Trade | Transatlantic | Internal / Inter-African | Notes |
---|---|---|---|---|
Asante Kingdom | Major exporter of slaves captured in wars | ✅ Yes | ✅ Yes | Became one of the largest suppliers of slaves from the interior; used slaves locally as well |
Denkyira | Early dominant state before Ashanti; traded slaves with Europeans | ✅ Yes | ✅ Yes | Controlled gold and slave routes before being defeated by Asante in 1701 |
Fante Confederacy | Middlemen between interior kingdoms and European traders on the coast | ✅ Yes | ✅ Yes | Often clashed with Asante; played both sides in slave and gold trade |
Akyem | Involved in wars with Asante; sold captives to Europeans | ✅ Yes | ✅ Yes | Also part of shifting alliances on the coast |
Akwamu | Early power in Volta/Eastern Region; raided for slaves | ✅ Yes | ✅ Yes | Had early access to coastal forts |
Wassa & Nzema | Coastal groups who sold captives to Europeans | ✅ Yes | ✅ Yes | Traded via Elmina and other forts |
Gonja Kingdom | Captured and sold war captives to northern or southern traders | Possibly | ✅ Yes | Linked interior trade routes to the south |
Dagbon (Dagomba) | Involved in slave raiding in the north; victims and traders | Possibly | ✅ Yes | Connected to trans-Saharan routes and southern markets |
Mamprugu | Older northern kingdom involved in raiding and trading | Possibly | ✅ Yes | Acted as intermediaries in northern trade |
Anlo/Ewe States | Sometimes victims, sometimes sellers depending on era | ✅ Yes | ✅ Yes | Engaged with Danish and British at Keta, Ada, etc. |
The Asante Kingdom likely benefited the most materially from the transatlantic slave trade among all Ghanaian kingdoms:
Their empire expanded through warfare, leading to many captives.
They traded gold and slaves for firearms, which further enhanced their military power.
Their central location allowed them to dominate internal trade routes leading to the coast.
The Denkyira also profited heavily in the early phase (17th century), but their defeat by Asante in 1701 marked a shift in power.
The Fante Confederacy gained significantly as middlemen, especially via trade connections at Cape Coast and Elmina, but their lack of central organization limited long-term control.
The trans-Saharan slave trade long predated European contact, with Arab and Berber traders moving slaves northwards to North Africa, the Middle East, and the Islamic world.
In Northern Ghana, kingdoms like Mamprugu, Dagbon, and Gonja interacted with Muslim traders, some of whom were Tuareg, Hausa, or other Sahelian groups with ties to Arab trade networks.
Slave raiding occurred between African Muslim kingdoms and their neighbors, with captives sold northwards, sometimes across the Sahara.
However, Arabs were not present in large numbers within southern Ghana or on the coast. The European slave trade (Atlantic) became dominant in the south by the 17th–19th centuries.
Wars and Raids: Kingdoms like Asante and Denkyira conducted wars or raids to acquire captives.
Captives Transported to the Coast: Via caravan routes through forest and savannah.
Sold to European Traders: At forts like Elmina, Cape Coast, Fort Amsterdam, Christiansborg (Osu), Anomabo, etc.
Exchanged for Goods: Firearms, alcohol, textiles, beads, and metals.
Shipped Across the Atlantic: To the Americas and Caribbean — part of the infamous Middle Passage.
While Europeans built the infrastructure of the Atlantic slave trade and profited massively from it through plantations and empire, some African kingdoms — including those in modern-day Ghana — were also complicit as suppliers and beneficiaries.
This complicity has been acknowledged in Ghanaian public discourse, and many traditional leaders, historians, and citizens are engaged in conversations about truth, reconciliation, and education regarding this painful past.
Some forts, such as Elmina Castle and Cape Coast Castle, now serve as UNESCO World Heritage Sites and places of remembrance.
The transatlantic slave trade was a global atrocity with deep local involvement. In Ghana, powerful kingdoms like the Asante and Denkyira enriched themselves by capturing and selling slaves, while others served as intermediaries or victims. The Arab (trans-Saharan) trade also played a major role in northern Ghana, especially among Muslim kingdoms.
Understanding this history requires honesty, nuance, and respect for the millions who suffered. But it also helps us better understand how power, wealth, and suffering were intertwined in both African and global history.
