During the colonial era, the Igbos in South East Nigeria did not have king. They practiced a decentralised system of administration. In other words, everyone had a say in the socio-political system of the community.
However, this system has been jettisoned. Today, Kings (Obi, Igwe or Eze) are numerous across the region. The Igbos system is almost similar with the Yoruba process of succession. It is hereditary, requires spiritual expiation of gods as well as wide consultation. The government will also contribute its own quota to the selection process.
