This book is an attempt to bring to limelight the issues surrounding Ogiamienism in Benin history. It traces Benin history from the Owere era to Ogisos with emphasis on Ogiso Owodo’s maladministration, the interregnum of Evian as a leader (Okaevbo) and Ogiamien’s insurgency. The history of Ekaladerhan and the Benin – Ife relationships was also brought to bear on how Oba Ewedo ruthlessly put paid to Ogiamienism with the memorable battle at Ekiokpagha in about 1255 AD which ultimately eliminated all forms of republicanism in Benin Kingdom. Concerned persons (indigenes and non-indigenes) where taken aback in 2015 when Ogiamien family tried to resurface the insurgency which had been eliminated about 800 years ago. This book once again is an attempt to trace the historical facts and highlight the truths of the matter for all people of goodwill.
