Most scholars have argued that Igbo society was "stateless" and that the Igbo region did not evolve centralized political institutions before the colonial period. According to this theory, the relatively egalitarian Igbo lived in small, selfcontained groups of villages organized according to a lineage system that did not allow social stratification. An individual's fitness to govern was determined by his wisdom and his wisdom by his age and experience. Subsistence farming was the dominant economic activity, and yams were the staple crop. Land, obtained through inheritance, was the measure of wealth. Handicrafts and commerce were well developed, and a relatively dense population characterized the region.

Despite the absence of chiefs, some Igbo relied on an order of priests, chosen from outsiders on the northern fringe of Igboland, to ensure impartiality in settling disputes between communities. Igbo gods, like those of the Yoruba, were numerous, but their relationship to one another and to human beings was essentially egalitarian, thereby reflecting Igbo society as a whole. A number of oracles and local cults attracted devotees, while the central deity, the earth mother and fertility figure, Ala, was venerated at shrines throughout Igboland.

The weakness of this theory of statelessness rests on the paucity of historical evidence of precolonial Igbo society. There are huge lacunae between the archaeological finds of Igbo Ukwu, which reveal a rich material culture in the heart of the Igbo region in the eighth century A.D., and the oral traditions of the twentieth century. In particular, the importance of the Nri Kingdom, which appears to have flourished before the seventeenth century, often is overlooked. The Nri Kingdom was relatively small in geographical extent, but it is remembered as the cradle of Igbo culture. Finally, Benin exercised considerable influence on the western Igbo, who adopted many of the political structures familiar to the Yoruba-Benin region.
