Indisputably, the origins of peoples and races are controversial, and that of the Binis' and the Yorubas is no exception. Organizationally, the Benin monarchy was structured to command the respect and loyalty of the Benin people and the envy of other ethnic nationalities. This drew the Portuguese, the first trans-Atlantic foreigners, to the ancient kingdom for exploratory and commercial purposes. The loyalty of the Binis towards the sustenance of the Benin Monarchy; its precious artefacts and cultural attributes is an expression of nationalism. This singular concept explains her imperialistic actions in north-eastern Yoruba land. The controversy attached to the historical origin of the Bini people linked with the Yoruba people is worthy of note. The Yoruba's allegiance to Ile-Ife as the cradle of their race aligns with Oduduwa's stead and civilisation. This intergroup relationship has brought about cultural similarities between the people of Benin and Yoruba, noting the position of Oranmiyan. This has necessitated a review into the dialogue-dispute that exists among history scholars of both derivations as to the point of link and level of relationship that had existed among them. The study?s position is curled from the existing historical facts. Using both primary and secondary sources, the study examines the historical narrations of scholars in assessing and establishing facts as to the relationship between them.
