The Ewu-born playwright, historian and poet Saintmoses Eromosele described Ewu as The Holy City in his book, The History and Chronicle of Ewu Monarchy: Since 1440. The monarchy of Ewu is believed to have been organized by Oba Ewuare, at about 1460 and was associated with Bini princes and warriors who made it their garrison in their quest to subjugate cotton and fabrics producing Esan tribes, especially the powerful Uzea kingdom. Prior to the coming of Oba Ewuare in the mid 15th century, the Ewu community was organized and governed by an ancient gerontocracy where a council of the oldest people called Edion administered the various villages that constituted Ewu, independently. But Oba Ewuare of imperial Benin Kingdom overturned the gerontocratic system of administration he met in his conquest of Esanland and enthroned some of his princes as viceroys in its place, and the Benin general Ozaine (a tradition renders his name an Oza became a viceroy of the Oba in Ewu and first Onojie of Ewu kingdom. These princes of Benin Empire checked the frequent rebellion and insubordination of the ancient, powerful Uzea and Uromi kingdoms in Esanland, and co-opted the Esan kingdoms into the then fast-expanding Benin Empire., Notwithstanding the origin of the Benin Empire occupation of Ewu in about 1460, Ewu people have various accounts of oral tradition which trace their pre-occupation existence to time immemorial. In all the accounts of origin, it is generally accepted that the people of Ehanlen were the aboriginals in the ancient land of Ewu. It is also believed that the people of Idunwele were migrant farm settlers and hunters from Emaudo in Ekpoma. It is believed that the people from Benin Kingdom were settled at Ihenmwen and Ukhiodo, especially among the families that occupy the area of Ewu known as Idumigun quarters. The people are believed to have originated from Igun in Benin City. The Ewu kingdom is ruled by the Ojeifo dynasty, which traces its roots via Ekpebua to Ozaine, the first Onoje of Ewu, who was a viceroy of the Oba Ewuare of Benin. The aboriginal peoples of Ewu are the Ehanlen people. Other settlers came from Igun and Ugbekun Quarters of Benin kingdom during the occupation of Ewu by the Benin imperialists. These settlers settled at Ihenwen at the quarters known as Idumigun. Later nomads and emigrants came from Emaudo in Ekpoma and settled in the areas known as Idunwele and Eko. Other waves of Benin emigrants fled from the tyranny of Oba Ewuare to Ewu and settled at Uzogholo, Idunwele and Ehanlen.
