The Onpetu of Ijeru, Oba Sunday Oladapo Oyediran Lagbami Osekun III, who doubles as the chairman of Ogbomoso South Local Government Traditional Council, clocked 25 years on the throne of his forebears on June 1, 2024, having ascended the throne on June 1, 1999. The Onpetu of Ijeru is not only an oba but also the head of the Oluoje lineage worldwide. Lineage in Yorubaland is called iran, that is, race. Bona fide Yoruba people, especially of Oyo stock, are identified by their lineages. Those who do not have oriki or orile adopted that of paternal or maternal lines for easy identification. Each lineage has a code of identification known as orile and lineage poetry called oriki. Through orile and oriki, each lineage preserves its separate identity, history, origin, culture and tradition. In the case of the Oluoje lineage, their orile is Aro, and part of their lineage poetry reads thus: “Omopaja fun lawo je, ela moko n ko gbodo je eye Ega, Omoosonu Ile o gbalo, emi ko ni se alo fun eniti ko feran mi, Omobunibuni, a bi ebu wontiwonti, Omo aroti we biojo.” As a prominent traditional ruler in Yorubaland, the Onpetu of Ijeru is unarguably one of the five obas with Oduduwa-sanctioned beaded crowns in Oyo State. Aside from these obas, namely, Alaafin, Olugbon, Aresa ,Olukoyi and Onpetu, all others wearing beaded crowns are either children, messengers or those who enjoy government’s magnanimity.
