The Igbo (Ibo) of the Northern Niger River Delta are one of the largest and most important tribal groups in West Africa. They are culturally highly complex, with a political system based upon a loose form of chiefdom/kingship in some areas, and a democratic panel of decision-makers in others. Social life was usually governed by a number of secret societies. Their main god is Chukwu (literally “Great Spirit”), the creator of the world, who is also linked to the sun and all that grows and lives. Social conduct is governed by Ogu-na-Ofo, spirits who defend the innocent against unjust charges. If a guilty person appeals to them for help, they will be cursed by Amadioha (the god of thunder and lightning). There are numerous other gods that deal with issues as diverse as Ahia Njoku (yams) to Ikenga (fortune and industry) and Agwu (medicine men). Each person has a god named Chi, which is essentially an embodiment of a person’s fate.
