The history of present-day Delta State stretches back centuries before the creation of the modern Nigerian state. The region developed through numerous kingdoms, chiefdoms, towns and riverine communities. Among the historic political formations were the Warri Kingdom, Agbor Kingdom, Aboh Kingdom, Okpe Kingdom, Isoko communities, Urhobo kingdoms and numerous Ijaw polities.
The rivers and creeks of the Niger Delta played a central role in settlement, transportation, fishing and trade. Communities developed around waterways including the Niger, Forcados, Escravos, Ethiope, Warri and Bomadi river systems.
The western Delta was particularly influenced by the Itsekiri kingdom centred around Warri. The Itsekiri developed extensive trading relationships with European merchants along the coast. The Warri Kingdom became an important political and commercial centre during the Atlantic trading era.
In the northern and central areas, communities associated with Urhobo, Isoko, Ukwuani and Anioma developed their own political and cultural institutions. These societies were connected through trade, marriage, warfare, migration and shared ecological systems.
