Igboland and the delta city-states
Many Nigerian peoples did not develop centralized monarchical states. Of these, the Igbo were probably the most remarkable because of the size of their territory and the density of population. The Igbo characteristic decentralized society seems to have been a deliberate departure from the earlier traditions of Nri; monarchical institutions in such outlying cities as Asaba, Onitsha, and Aboh probably arose through the influence of the kingdoms of Igala and Benin. Igbo lineages were organized in self-contained villages or federations of village communities, with societies of elders and age grade associations sharing various governmental functions. The same was true of the Ijo of the Niger delta and peoples of the Cross River area, where secret societies also played a prominent role in administration. Monarchical structures began to emerge by the 18th century in response to the needs of the overseas trade.
Initially, Portuguese contacts focused on Benin and Warri. By the 17th and 18th centuries, at the height of the slave trade, the delta city-states had become the principal outlets of that activity. Various coastal communities organized themselves as entrepôts of the slave trade, so that they would not also become its victims. Similarly, the Igbo, like the Benin and Yoruba kingdoms, supplied slaves to the coast, although Benin had largely ended its involvement in the Atlantic slave trade by the 18th century. The deleterious effect of the slave trade on the society and the economy was felt everywhere, but, in terms of loss of population, those who suffered most appear to have been the noncentralized peoples of the middle belt. The trade also caused severe economic and political dislocations, intercommunal rivalries, and the forced migrations of millions of people out of Nigeria.
