The origin of Oyi people is the same for all the "OLU" sub group of the Eri-AwkaIgbo. The Olus are the distinct river-side Igbo people of the lower Anambra plain, encompassing the entire old Anambra Division of the 1920s to the 80s, parts of today's Awka North LGA of Anambra State and the excision of the former Uzo-Uwani LGA of now Enugu State. A number of Olu people also speak Igala language. In fact, Igala kingdom is considered to have been founded by an Olu 'refugee' prince. Olu trace their origin to Eri. Onitsha and Ogbaru areas by character and dialect, are sometimes considered as Olu. It is said that the more ancient forms of Igbo Tradition and Cultural practices like music, marriage ceremony and religious worships are those still practiced by the Olu.
Lifestyle
Oyi people, like other Olu people, are usually tall, care-free and socially progressive people. Olu life used to be nature-centered until the white man upset all that with his "civilisation". Olu or riverine Igbo have very elaborate ceremonies, festivities and roles. They are quite egalitarian in belief and republican in their political pursuits. Oyi practice a Jewish-like Kabbalah system of self-actualisation which is embedded in the apical Nze-na-Ozo tradition of "Onye chizue; o bulu Mmoo, bulukwa Mmadu". Translated, this simply says that the Ozo initiation is a threshold vista of self-distinction that transforms the initiates into both man and spirit or "spirit-man". This ancient Ozo system called Ozo-Atulukpa-Okala was instituted in Umunya as far back as the late 16th Century by a war chieftain named Igboegbunammadu Onenulu. He equally bequeathed the title to his friends within the Olu sub-clans, from Ogbunike to Awkuzu and it is severally called and known as 'Ozo-Ndi-Ichie,' 'Nnekwu Ozo,' etc.
Council history
Oyi is a Local Government Area of Anambra State, southeastern Nigeria. The towns that make up the local government are Nkwelle-Ezunaka, Awkuzu, Ogbunike, Umunya and Nteje. Oyi is in the epicenter of the present Anambra State and was first created by the Civilian Administration of Chief Jim Ifeanyichukwu Nwobodo in the 1980s with Umunya as its Headquarters, with Ogbefi Jasper Nwobi as its first chairman. It took its name from the pacific and famous Oyi River that flows northwards into Omambala. When the military sacked the civilian administration of Alhaji Shehu Shagari under which Chief Jim Nwobodo was governor in 1983, Oyi and its constituent towns were drawn back into the old Anambra Local Government Area with Otuocha as headquarters. Later, under the administration of Col Nnameka Akonobi as Governor under Gen Ibrahim Badamosi Babangida, Enugu became a State and the former Uzo-Uwani Local Government Area towns of Omor, Omasi, Umueje, Umelum, Igbakwu, Umumbo, Anaku and Ifite Ogwari were merged with their more "Olu" brothers in Oyi. Nteje became the headquarters and has remained so even after the excision of the towns into now Ayamelum Local Government Area.

There are meandering brooks and streams across the area and one of them enters a hole to 'the unknown'.
