THE IGBO ARE NOT CONFINED TO FIVE STATES: THE HISTORICAL RECORD, THE RIVERAIN IGBO AND THE CASE FOR AN IGBO REGIONAL HOMELAND
Nigeria's present political boundaries cannot erase the historical geography of the Igbo people. There is an uncomfortable truth that Nigeria has consistently avoided confronting: the political map of Nigeria is not the ethnic map of Nigeria.
Nigeria's states are relatively recent political creations. The peoples inhabiting those territories existed before the creation of the Nigerian federation, before the regional structure of the First Republic and, in many cases, before British colonial rule.This distinction is particularly important in the case of the Igbo people.
Today, the Igbo are commonly presented as a people occupying five states — Abia, Anambra, Ebonyi, Enugu and Imo. That description may be convenient for contemporary Nigerian administrative purposes, but it is historically incomplete.
The question is not whether those five states constitute the present South-East geopolitical zone. They do.
The question is whether the boundaries of those five states constitute the complete historical, linguistic and ancestral boundaries of the Igbo people.
A HISTORICAL DOCUMENT THAT CANNOT BE DISMISSED
The attached historical table is headed:
“THE IBO-SPEAKING PEOPLES — TABLE IX — (C) RIVERAIN IBO.”
It then proceeds to identify 23 Riverain Ibo groups and communities.
Among the communities listed are:
Nzam, Anam, Asaba, Oko Okwe, Atani, Ossomari, Ossissa, Abarra, Umuabarra Utechi, Okpai, Aboh, Ndoni, Afor, Ase, Ashaka, Ibede, Oguta, Izombe, Awarra, Egbema, Oba and Ekpeya (Ekpaffi), together with eight unclassified villages. �

The table does something even more important.
It does not merely list these communities as geographically adjacent to the Igbo.
It places them under the heading “Riverain Ibo” and “The Ibo-Speaking Peoples.” �
824021.jpg
The table also records their political divisions as Onitsha, Aboh, Owerri and Ahoada. In other words, the political administration of the period did not erase their classification as Ibo-speaking peoples.
This is a crucial historical distinction.
Political administration and ethnic identity were not necessarily the same thing.
THE 23 COMMUNITIES ARE NOT MODERN MIGRANTS
This point deserves emphasis.
When an Igbo man from Enugu moves to Lagos today, nobody should confuse his presence in Lagos with the proposition that Lagos is an ancestral Igbo territory.
That is migration.
But that is not what the historical table is describing.
The table was documenting communities, not individual migrants.
It recorded their local communities, their social classification and their estimated adult male populations during 1935–1940. The table gives an approximate total of 46,600 adult males for the Riverain Ibo groups it recorded. �
824021.jpg
That is historical evidence of established populations.
It is therefore intellectually dishonest to dismiss the Riverain Igbo question simply by saying:
“Those are Igbo people who migrated there.”
The document predates the contemporary state structure and records established communities as part of the Ibo-speaking peoples.
THE RIVERAIN IGBO ARE PART OF THE LARGER IGBO STORY
The historical work from which the table derives is even more explicit.
Forde and Jones divided the Ibo-speaking peoples into several broad regional divisions, including Northern or Onitsha Ibo, Southern or Owerri Ibo, Western Ibo, Eastern or Cross River Ibo and North-Eastern Ibo. They specifically classified the Riverain grouping under Western Ibo, with communities spread across the then administrative divisions of Ogwashi Uku, Onitsha, Owerri and Ahoada. �
Perlego
This is enormously significant.
It means that the historical conception of the Igbo was not limited to today's five South-East states.
Indeed, the same historical classification recognised the Western Ibo and Riverain Ibo as components of the wider Ibo-speaking population.
Therefore, anyone who says:
“There are only five Igbo states”
is confusing a modern political arrangement with a much older ethno-linguistic reality.
THE NIGER RIVER DID NOT CREATE THE IGBO
One of the arguments frequently advanced against the broader Igbo identity of communities west of the Niger is geographical.
The argument is essentially:
“They are west of the Niger; therefore they cannot be Igbo.”
That argument is historically weak.
Rivers are geographical features. They do not automatically create ethnic boundaries.
The Niger existed before Nigeria.
The Igbo existed before Nigeria.
The communities along the Niger existed before Nigeria.
People crossed the Niger, settled on either side, intermarried, traded, fought wars, formed alliances and maintained ancestral relationships across it.
The historical classification of the Riverain Ibo is therefore particularly important because it demonstrates that the river did not constitute an absolute barrier to Ibo linguistic and cultural identity.
THE ANIOMA QUESTION
The same reasoning applies to the Igbo-speaking communities of present-day Delta State.
The Western Ibo classification identified a substantial population west of the Niger, including the Northern Ika, Southern Ika and Riverain divisions.
Perlego Modern scholarship continues to examine the linguistic and identity politics of the West Niger Igbo. One recent study describes the West Niger Igbo as extending along the western bank of the Niger and notes that the region's boundaries have often been constructed through political rather than purely ethnolinguistic considerations.
ResearchGate
That is precisely the point.
The fact that some communities possess Edo, Igala, Ijaw or other historical influences does not automatically destroy their Igbo connection.
Ethnic history is rarely genetically or culturally “pure.”
The historical record itself describes the Riverain Ibo as culturally and linguistically diverse.
But diversity within a people does not necessarily mean absence of relationship between the constituent communities.
RIVERS STATE AND THE IGBO QUESTION
The Rivers State question becomes even more interesting when viewed against this historical background.
The table lists Egbema, Oba and Ekpeya (Ekpaffi) among the Riverain Ibo communities and associates them with the Ahoada political division.
This is important because Ahoada is firmly within what later became Rivers State.
Therefore, the historical question cannot simply be reduced to:
“Igbo people migrated into Rivers State.”
The historical record demonstrates that communities in the territory that subsequently became part of Rivers State were already being classified within the Ibo-speaking population.
The modern political identity of Rivers State came later.
This does not mean that every present-day Rivers community is Igbo.It does not mean that every Rivers person must identify as Igbo.
It means something much narrower — and much more defensible:
There were historically established Ibo-speaking communities in territory that is today located within Rivers State.That fact deserves recognition.
THE DOCUMENT ALSO SHOWS WHY THE TERM “TRIBE” MUST BE HANDLED CAREFULLY
There is another lesson in the table.
It uses classifications such as Tribe (T), Sub-tribe (ST), Group (G) and Village Group (VG).
824021.jpg
This demonstrates that the Igbo world was not historically a single centrally governed kingdom.
The Igbo were composed of numerous autonomous communities, clans and groups.
Therefore, someone cannot reasonably argue:
“There was never an Igbo kingdom, therefore there was never an Igbo people.”That would be a fundamental misunderstanding of Igbo political history.
The absence of one centralised precolonial Igbo monarchy does not mean the absence of a common linguistic or cultural population.
Indeed, Forde and Jones explicitly described the Ibo as a single people in the sense that they spoke related dialects, occupied a continuous territory and shared important social and cultural characteristics, while simultaneously recognising that political authority was dispersed among many local groups. That description remains extraordinarily relevant today.
WHAT THEN HAPPENED TO THE IGBO?
The answer is simple:
Nigeria's political restructuring divided them.The colonial administration did not construct Nigeria according to a perfect map of ethnic homelands.
Subsequent governments created provinces, regions and states for administrative and political reasons.
The result is that communities historically connected through language, ancestry and culture were placed under different political administrations.
Some became part of the Eastern Region.
Some became part of the Mid-Western Region.
Some became part of Rivers State.
Some became part of Delta State.
Others became part of neighbouring administrative territories.
The creation of a state does not automatically create a new ethnicity.
THIS IS WHERE SCIENTIFIC ANCESTRY RESEARCH BECOMES IMPORTANT
There is a legitimate case for a comprehensive scientific investigation of the ancestry of Nigeria's peoples.
Such a study should not begin with the conclusion that every community must be Igbo.
It should begin with an open question:
What are the population relationships among the peoples historically inhabiting the Lower Niger, Niger Delta, Cross River basin and adjoining regions?Modern population genetics can examine ancestry and genetic relatedness.
Historical linguistics can compare languages and dialects.
Anthropology can examine social institutions and cultural practices.
Archaeology can investigate settlement patterns.
Genealogy and oral history can reconstruct migration traditions.
When all these forms of evidence are considered together, Nigeria could produce a far more accurate map of its historical peoples.
That would be far superior to assuming that today's state boundaries are ancient ethnic boundaries.
CAN DNA PROVE THAT SOMEBODY IS IGBO?
This question requires precision.
DNA can provide evidence of population ancestry and genetic relationships.
It cannot, by itself, determine what ethnic identity an individual must personally adopt.
A person may possess ancestry associated with several populations and nevertheless identify culturally with one community.
Therefore, DNA should not be used to tell someone:
“You deny being Igbo, therefore your DNA proves you are Igbo.”
That would go beyond what genetics can scientifically establish.
But DNA can legitimately be used to investigate a much more important question:
Do populations presently separated by Nigerian state boundaries exhibit substantial evidence of common ancestry or historical population interaction?That is a scientifically testable proposition.
And it deserves to be investigated.
THE CASE FOR AN IGBO REGIONAL HOMELAND
The logical conclusion is not that Nigeria should simply redraw its map tomorrow.
The conclusion is that Nigeria should recognise the historical geography of its peoples when considering constitutional restructuring.
If comprehensive research confirms that substantial indigenous Igbo populations exist across the five South-East states and historically connected territories in neighbouring states, then there is a strong argument for creating a constitutional arrangement that recognises the Igbo as a regional people rather than merely the population of five administrative states.
Such an arrangement could be achieved through genuine federal restructuring.
It could provide for:
an Igbo cultural and linguistic region;
coordinated regional development;
protection of Igbo ancestral communities outside the present South-East;
preservation and promotion of the Igbo language;
common cultural institutions;
regional economic planning;
protection of traditional institutions;
constitutional recognition of historical communities; and
democratic consultation with affected populations.
This does not necessarily require the destruction of Nigeria.
Indeed, true federalism may be the mechanism that makes Nigerian unity sustainable.
THE THIRTEEN-STATE QUESTION
If the objective is to establish an accurate Igbo ancestral region, the study should not begin by assuming that the answer is five states — or even thirteen states.
It should investigate all thirteen states proposed by the historical and contemporary claims and determine, community by community, where indigenous Igbo or historically connected Igbo-speaking populations actually exist.
That investigation should distinguish between:
1. Core Igbo populations;
2. Western/Delta Igbo populations;
3. Riverain Igbo populations;
4. Cross-River Igbo populations;
5. Igboid populations with distinct contemporary identities;
6. Mixed historical populations; and
7. Communities that are genuinely distinct from the Igbo.
That classification would be much more powerful than simply declaring that every community in a particular state is Igbo.
UNITY DOES NOT REQUIRE ERASURE
The argument for Igbo unity should not become an argument against other Nigerian peoples.
The Igbo can assert their history without denying the identity of the Ijaw.
They can assert their ancestral relationships without denying the Edo.
They can defend their language without denying the Igala.
They can demand regional recognition without denying the Ibibio, Annang, Efik, Oro, Urhobo, Isoko or any other people.
Indeed, the strongest case for Igbo recognition is one that respects the right of every other Nigerian people to make the same demand.
CONCLUSION: THE HISTORICAL RECORD HAS ALREADY OPENED THE DOOR
The attached document gives us something more valuable than political rhetoric.
It gives us a historical classification.
In the period 1935–1940, the Riverain communities listed in the table were documented under “The Ibo-Speaking Peoples” as “Riverain Ibo.” Twenty-three groups were identified, including communities associated with the political divisions of Onitsha, Aboh, Owerri and Ahoada. The table estimated approximately 46,600 adult males among the listed Riverain Igbo population.
That historical evidence cannot be erased by the subsequent creation of Nigerian states.
The lesson is not that every person living in those territories today must adopt an Igbo identity.
The lesson is that the historical geography of the Igbo is demonstrably larger and more complicated than the five-state South-East geopolitical zone.
Therefore, Nigeria needs a new conversation.
Not a conversation based on propaganda.
Not a conversation based on hatred.
Not a conversation based on political convenience.
A conversation based on history, linguistics, anthropology, genealogy, archaeology and population genetics.
Let the evidence establish the boundaries.
Let indigenous communities speak for themselves.
Let science investigate ancestral relationships.
And let constitutional democracy determine how historically connected communities should be represented.
But one principle should no longer be controversial: A political boundary created by the Nigerian state cannot, by itself, rewrite the history of a people who existed before that boundary was created.
The Igbo question therefore deserves to be reconsidered not as a demand for privilege, but as a question of historical recognition, cultural survival and constitutional justice.
If Nigeria genuinely believes in federalism, then it must be prepared to recognise the peoples that constitute its federation.
The Igbo should not have to choose between being Nigerian and being Igbo.
They can be both.
And if historical and scientific evidence establishes that their indigenous communities extend across a geographical area larger than today's five-state South-East, then Nigeria should have the constitutional imagination to accommodate that reality.
The map may divide the Igbo politically. It cannot be allowed to erase their history.
Important source note: The attached image is particularly useful because it gives us a contemporaneous historical classification, not a modern social-media claim. However, it does not by itself prove that Igbo communities existed in 13 present-day Nigerian states. What it proves is the historical classification of the listed Riverain communities as Ibo-speaking/Riverain Ibo.
The 13-state proposition should therefore be presented as a researchable historical and constitutional claim, with the additional states established through separate documentary, linguistic and population-genetic evidence.
