The Igala mega state attained the height of its fame during the mid-17th century. The Idah-Benin war (1515-1516) was a war of mutual independence. The Igala state reached its political and commercial supremacy afterwards, when it became a leading exporter of choral beads, horses, medicine, skills and of course, slaves to the coastal region. Its growing economic power, nevertheless, changed the dynamics of the earlier complex relationships with several Idoma communities. The Igala people are found in villages and towns across the Nigerian state of Kogi. In each town or village where they are more than a thousand of Igala people, a chief (Oga Attah) which is a representative of the Attah Igala is crowned.
