Lesson Content/Board Summary
States in Pre-Colonial Nigeria
What are Centralized States?
Centralized states are political systems where power and authority are concentrated in a central governing body, such as a king, paramount chief, or council, rather than being diffused among many smaller, independent units. These states often had organized administration, a defined territory, and a hierarchy of authority.
Characteristics of Centralized States
The following are common characteristics of centralized states:
- A recognized leader or ruler (e.g., king, chief).
- A well-defined territory and population.
- An organized system of government and administration.
- A means of collecting revenue (taxes, tributes).
- A standing army or system for defense.
- Clear laws and a judicial system.
Examples of Centralized States in Pre-colonial Nigeria
i) The Niger Delta City States
The Niger Delta region was home to several powerful city-states such as Bonny, Brass, Opobo, and Nembe. These states were primarily organized around trade, especially the lucrative palm oil and slave trade with European merchants. Their political structure was often based on a “House System.”
Key features of the Niger Delta City States:
- House System: This was the basic socio-political and economic unit. A “House” comprised a wealthy merchant, his family, servants, and slaves, all loyal to him. The head of the House was often called a “Chief.”
- Economic Basis: Dominated by trade, particularly in palm oil and slaves.
- Political Authority: Power was usually shared between the head of the ruling House and a council of other House Chiefs.
- Maritime Focus: Their location along the coast and rivers made them strategic trading hubs.
ii) Calabar
Calabar, located in the southeastern part of Nigeria, was another significant centralized state, particularly Old Calabar. It was known for its vibrant trade and unique political organization. The Efik people were the dominant group.
Key features of Calabar:
- Efik Dominance: The Efik people established a sophisticated society with strong cultural and political institutions.
- Trade Hub: Calabar was a major center for the transatlantic slave trade and later for palm oil trade. Its strategic location on the Calabar River was vital for trade.
- “Egbo” Society: A powerful secret society called “Egbo” (Ekpe) played a significant role in political administration and law enforcement. It enforced laws, settled disputes, and regulated trade. Membership was hierarchical and influential.
- Obong: While the Egbo society held considerable power, the “Obong” (king or paramount ruler) was the recognized political head, though often with limited direct authority compared to the Egbo council.
- Village/Town Council: Decisions were often made through councils of elders and heads of extended families.
