Obalumo
Obalúmò (or Oba'lúmò , a contraction of Oba Olúmò), is the name and title of the founder-king of the ancient Ìsèdó-Olúmọ̀ City-State of the Igbomina. A classical translation of the title Oba’lúmò is “The King, the Lord of Knowledge”, meaning “ Knowledgeable King” or “King of the Lords of Knowledge,” a description which suggests that this founder-king of the Ìsèdó city-state, who is reputed in oral history to be a veteran hunter, was also a highly skilled Herbal doctor/pharmacognosist and Babalawo (a diviner priest of the Ifa oracle).
Some oral history ascribe a personal name of Tìímò to the first King Oba'lúmò. Tìímò led one of the migrations from the Òbà kingdom perhaps as a result of the cyclic conflict with their Nupe neighbours. The orature of the Ìsèdó people refer to their recent ancestry from King Oba'lúmò (Omo Ọba’lúmọ̀ n’Ìsèdó), as well as to a more ancient lineage of King Olúnlákin of Òbà (Ọm’Ọba Olúnlákin).
Results of recent archeological research of the region's contemporary and later settlements suggest that that the Ìsèdó City-State commonly known as Ìsèdó-Olúmò (i.e. the Olúmò’s Ìsèdó), was established between the 10th and the 12th centuries by Òbà refugees displaced from the cyclic conflicts of their former kingdom with the neighbouring Nupe to the north.
Oratures of ancient origin and oral-historians ascribe the role of land-grant authority to the Oba'lúmò of Ìsèdó. These sources report that at the request of Oduduwa’s fourth son Òràngún, the region’s king Oba'lúmò gave land-grants to the later arriving Òràngún immigrants at a location sufficiently removed from Ìsèdó’s location.
An annual festival called "Imarugbo" is observed by the Òràngún, who pays a day-long visit to the Oba'lúmò in his palace in homage to his primogenitor and for hosting the Òràngún's elderly mother who could not continue with the immigrant party to the location of their allocated land. The Òràngún's mother died in the palace of the Oba'lúmò and was buried at Ìsèdó.
