Umunya is an Olu Town and one of the five communities that make up Oyi Local Government Area (LGA) of Anambra State Nigeria; it is bordered by six neighbors: Ifite-Dunu, Awkuzu, Nteje, Nkwelle-Ezunaka, Ogbunike, and Umudioka. In the south lies Umudioka and Ifite-Dunu, both in Dunukofia LGA. In the north, Nteje and Nkwelle-Ezunaka. In the east, Awkuzu and in the west, Ogbunike. The boundaries are naturally demarcated by streams except at the border with Nkwelle-Ezunaka where an expanse of Umunya heath namely, Oli-Omoto, Ogwugwu-Obo, Ugwueze, etc. crossed the Kpokili River. Nearly all ten villages of Umunya have their own fresh water springs. The town is blessed with fertile lands; hence, its economy is based on agriculture.
It is a town of ten villages namely Ezi-Umunya, Okpu, Ojobi, Umuebo, Amaezike, Ajakpani, Odumodu-Ani, Isioye, Odumodu-Enu and Ukunu. These villages are sub-grouped into Ezi, Ifite and Ikenga sub-divisions, the tri-partite heritage of all Gadite H/Igbos commonly referred to in anthropological history as ERI-AWKA Igbo.
The founder of Umunya is called Nya who was the son in-charge of the fleets of ERU, the progenitor of the Igbos of Guinea Forest West Africa. The story had it that River Omambala was joined by Isi-Ogwugwu, a fast flowing river that then encompassed the present Umunya area. Isi-Ogwugwu was believed to have created the rolling topography nature of the area as it is today. The scenic depression of Urunda towards Ogbunike is commonly cited by story-tellers, to credit this myth.
The story goes that on a certain Eke day as Nya was ferrying fishermen and farmers across the stupendous Isi-Ogwugwu water course, he was struck by a moving flash in the river that followed an unusual wave swirl. The remarkable nature of the 'whirl and twirl' of the flash made Nya to suspend work in reverence to a river goddess, who he believed was passing to Eke market, in the west. As he went out to rest, he was shown a vision of a stone upon which he will establish a community of farmers who will become his own people. When he woke up, he discovered that the river had receded further beyond where he tied his canoe. This he took as a confirmation of his dream. He therefore settled here at the place known as "Ilo-Umuebo". This Ilo-Umuebo is now the center-court of High Justice in Umunya, where truth must be told. He brought his kinsmen and friends and founded the community known today as Umunya (UMU NYA, i.e. “Children of Nya”).
