[3] According to Benin tradition, the Edaiken was expected to live outside the capital among the hereditary chiefs, but Olua chose not to do so out of fear of his elder brother Okpame.

[4] He gave a cow's leg to an old woman who wanted meat, and a coral bead to a man whom he saved from drowning.

In one instance, he requested wine from the royal wine-maker, who responded that there was none and suggested that Olua should produce it himself.

[5] However, this action led to Iginuwa becoming disliked by the Binis for his advice, leading them to decide not to accept him as their Oba after Olua's death.

[5][3] Knowing his elder son Iginuwa's lack of popularity, Olua decided to create a kingdom for him by the sea.

[7] To keep the plan hidden from his chiefs, Olua asked them to send their sons with Iginuwa to perform a sacrifice for him by the sea.

[5] Olua prepared a large box filled with royal attire and other items for Iginuwa, placing sacrificial victims on top to conceal the contents.

[9] The Ijaw taught the Benin immigrants skills such as swimming, fishing, and adapting to the marine environment.

[7][6] His brother, Ozolua, succeeded him, ascending the throne after a three-year interregnum during which a republican form of governance was in place.

[2][6] Ozolua, an Oba known for his military campaigns, conquered several lands and peoples, including the Idanre, the Igala, and the Nupe.
