The society combines a kind of freemasonry with political and law enforcing aims. For instance any member wronged in an Ekpe district, that is one dominated by the society, has only to address an Ekpe-man or beat the Ekpe drum in the Ekpe-house, or blow Ekpe as it is called, i.e., sound the Ekpe horn, before the hut of the wrong-doer, and the whole machinery of the society is put in force to see justice done.[1]
