The history of the city of Owerri, the capital of Imo State, dates back centuries. According to oral traditions, its story is a tale of family ties, migration, and the establishment of a new centre in the very heart of the Igbo lands. The city was founded in the 14th century by a man named Ekwem Oha. Legend has it that he was forced to flee his native settlement of Uratta following a dispute with his younger brother. In search of a new home, Ekwem Oha settled on a hill known as Ugwu Ekwema, which became the nucleus of the future city. The initial settlement expanded over time, and his descendants established five villages that formed the foundation of Owerri, known as "Owere Nchi Ise".
The city's establishment was facilitated by its strategic location on fertile lands between the Otamiri and Nworie rivers, creating favourable conditions for agriculture. During the colonial period, Owerri acquired significant administrative importance: on 11 May 1902, British authorities established it as a district headquarters, and it later became a provincial capital. A key moment in the city's modern history was gaining the status of the capital of Imo State in 1976, which gave a powerful impetus to its development. The region's economy historically relied on agriculture, particularly yam cultivation and palm product production, later supplemented by oil and natural gas extraction.
Early Owerri society was agrarian, and its culture was closely tied to the land and rivers. For instance, fishing was only permitted in the Otamiri River. One of the most important cultural events, the "Oru Owere" festival, is held annually to commemorate the founding of the city and is linked to the founder's first meal. Also iconic to the region is the "Mbari" cultural tradition—the creation of ritual clay sculptures in honour of the earth goddess Ala. These traditions remain deeply rooted in the life of the local community to this day.
