‘Situation in West Africa c.1600; reasons for rise of Oyo and Dahomey Empires and relationship between them: military/ cavalry, infantry/firearms, political change, the importance of individual rulers; political, social, military.’
West Africa around 1600 was a dynamic region marked by shifting powers, expanding trade networks, and evolving political systems, laying the groundwork for the rise of Oyo and Dahomey.
The Situation in West Africa c.1600
By the early seventeenth century, West Africa was shaped by the collapse of earlier empires such as Mali and Songhay, leaving fragmented states and opportunities for new powers. Coastal regions became increasingly significant due to European trade links, while the interior remained connected through trans-Saharan routes.
Political Landscape
Older empires in decline created space for regional states to expand.
Smaller kingdoms and city-states were vulnerable to conquest or alliance.
Political fragmentation encouraged centralising rulers to consolidate authority.
Economic Conditions
Trans-Saharan trade continued to carry salt, gold, and slaves.
Coastal trade routes with Portuguese, Dutch, and other Europeans expanded, introducing firearms and luxury goods.
Increased access to weapons gave ambitious rulers opportunities for military expansion.
Social and Cultural Influences
Islam influenced northern and inland regions, while traditional religions remained strong in forested areas.
Kinship structures and hierarchical social systems supported centralised authority.
Prestige of rulers grew through ritual, religion, and warfare.
Reasons for the Rise of the Oyo Empire
The Oyo Empire emerged in present-day Nigeria, building on its favourable geography and military strength.
Geography and Location
Located in the savannah-forest transition zone, Oyo controlled trade between northern caravan routes and southern coastal markets.
Fertile lands supported agriculture, sustaining population growth and armies.
Military Factors
Cavalry became Oyo’s greatest asset.
Cavalry: Mounted troops used in warfare, offering speed, mobility, and shock power
Open savannahs supported horse breeding and use of cavalry in large-scale campaigns.
Firearms obtained through coastal trade were gradually integrated, strengthening infantry forces.
Political Change
Centralised rule under the Alaafin (king) gave coherence to expanding territories.
The Oyo-Mesi (council of chiefs) balanced royal power, preventing instability.
Tribute from conquered peoples strengthened the state financially and politically.
Role of Individual Rulers
Early Alaafins led campaigns of conquest that expanded Oyo’s domain.
Wise rulers stabilised succession, reinforcing central authority.
Reasons for the Rise of the Kingdom of Dahomey
The Kingdom of Dahomey, located in present-day Benin, developed slightly later but rapidly became a major power.
Geography and Location
Dahomey occupied fertile plateau land inland from the coast.
Its position allowed it to control routes between the coast and interior, strategically placing it in the Atlantic trade.
Military Strength
Known for disciplined infantry, including the famed female regiments, later termed the Amazons.
Firearms from European traders boosted Dahomey’s capacity for conquest and defence.
Military organisation was centralised, with loyalty directly tied to the king.
Political Change
The monarchy became the heart of state power, with kings exercising strong authority.
Conquered areas were integrated through tribute systems and appointment of royal officials.
Expansion was systematic, designed to strengthen the state’s economy and influence.
Role of Individual Rulers
Rulers such as King Houegbadja laid foundations of political centralisation.
Successors used military campaigns to expand Dahomey and control the slave trade.
The Relationship Between Oyo and Dahomey
The rise of both states was closely connected, with competition and dominance shaping their histories.
Military Interactions
Oyo’s cavalry dominance often gave it the upper hand in conflicts with Dahomey.
Dahomey’s infantry relied on firearms, allowing resistance but not permanent independence.
Tribute and Clientage
By the late seventeenth century, Dahomey became a tributary state to Oyo.
Tribute payments included slaves and goods, reinforcing Oyo’s dominance.
Political and Social Impacts
Oyo’s supremacy influenced Dahomey’s policies and military reforms.
Dahomey’s centralised system ensured survival despite subordination, and it retained significant internal independence.
Oyo’s hegemony over Dahomey created a tributary corridor to the Slave Coast, knitting together hinterland cavalry power and Atlantic exchange.

Broader Political, Social, and Military Context
The growth of Oyo and Dahomey reflected wider developments across West Africa.
Political
Centralisation was a key theme, with rulers seeking tighter control over administration.
Succession systems were refined to reduce instability.
Social
Religion played a role in legitimising rulers, with ceremonies reinforcing authority.
Hierarchical societies allowed rulers to command tribute and labour.
Military
The combination of cavalry, infantry, and firearms created diverse military strategies.
Expansionist policies ensured access to trade routes, slaves, and resources.
At Abomey, royal palaces, court ceremony and narrative bas-reliefs projected centralised authority and militarised kingship.
Importance of Trade in the Rise of Both Empires
The Atlantic slave trade was critical: both empires captured and sold captives to Europeans.
Firearms and luxury goods from trade reinforced internal hierarchies.
Control of trade routes was both a cause and consequence of expansion.
Dahomey’s infantry—supported by Atlantic firearms and drill—offset cavalry advantages in the forest belt and underpinned the kingdom’s expansion.

Final Considerations
By 1600, West Africa was undergoing transformation. Oyo rose through cavalry and political centralisation, while Dahomey grew through infantry discipline, firearms, and monarchy. Their relationship combined rivalry and domination, exemplifying the political, social, and military forces shaping the region.
FAQ
Oyo’s savannah location was ideal for maintaining cavalry forces, as horses thrived in open grasslands and could manoeuvre effectively. The flat terrain also enabled large-scale mounted campaigns.
By contrast, Dahomey was based in forested and plateau regions where horses were far less effective. This environment favoured well-drilled infantry armed with firearms. Geography, therefore, explains the contrasting reliance on cavalry in Oyo and infantry in Dahomey.
European traders supplied firearms via coastal exchanges, introducing a new military dynamic.
States like Dahomey, closer to the coast, integrated muskets into infantry formations.
Oyo also benefited, but cavalry remained dominant inland.
Neighbouring smaller states, without similar access, were at a disadvantage and often fell under Oyo or Dahomey control.
This shift reinforced centralised powers that could regulate trade routes and maintain disciplined armies.
Tribute symbolised political subordination and economic exploitation. Dahomey was required to send slaves and goods to Oyo, demonstrating its dependency.
Tribute allowed Oyo to:
Finance its armies and further conquests.
Reinforce loyalty among chiefs by redistributing wealth.
Undermine Dahomey’s independent authority, as rulers were forced into acknowledgement of Oyo supremacy.
The system tied Dahomey into Oyo’s sphere without direct annexation, maximising Oyo’s power while minimising administrative costs.
In Oyo, the Alaafin claimed semi-divine status, reinforced by rituals and ceremonies linking him to deities. The Oyo-Mesi chiefs balanced this power but still recognised sacred kingship.
In Dahomey, kings used Vodun religious traditions and court rituals to elevate themselves above ordinary subjects. Sacred ceremonies at Abomey reinforced their right to lead militarily and politically, giving divine sanction to expansion.
Both empires combined political centralisation with spiritual legitimacy to strengthen rule.
Oyo dominated inland caravan routes, controlling links between the Niger and the coast. This gave it leverage over Dahomey, which was closer to coastal trading ports.
By making Dahomey a tributary, Oyo secured access to European trade while maintaining its inland control. Dahomey, though subordinate, benefitted by acting as a middleman in the slave trade, supplying captives to Europeans and firearms to its hinterland.
The trade relationship was therefore both exploitative and mutually reinforcing, shaped by strategic geography.
