ILOBU is the administrative headquarters of Irepodun Local Government. It has a population of about 220825 (1998 Census), (1995 census was 194,400). Ilobu is located in a sparsely forested area and is bounded in the north by Ifon-Osun, in the south by Osogbo, in the east by Oba and in the west by Erin-Osun, and is watered by Ojutu river, Elentere river, Konda river and a few other streams.

llobu society is characterised by the existence of traditional offices which played and still play definite roles in the affairs of the society. At the apex of the administrative system is the Olobu chosen in rotation from four ruling houses, which share the same blood relationship.

The Olobu rules the town through a chain of the most senior chiefs. The chiefs are known as 'llu' or 'Town Representatives'. The 'llu' is headed by Bara, who is regarded as next in rank to the Olobu. The other senior chiefs are Jagun, Balogun and Balegbobamu. Women also play an active part in the traditional and political administration of llobu and are given a voice through their political representative, Iyalode, who is assisted by her Otun Iyalode and Seriki, second and third in rank respectively.

Next to the llu, come the Bale (heads of households). The Bales represent their different households. They do not hold meetings together except when called together by the Olobu and his chiefs. The oldest man in the compound is usually elected as the Bale. It is required that all members of a household should be able to trace their descent from a common ancestor. The unit is strictly exogamous and sexual relations between members are regarded as incestuous and are punishable by the gods of the community.

Another administrative unit is the Olorisa (Priests) consisting of the Oluawo, Oluode, Mogba and Alagba. This unit helps in the administrative system of the town and is the custodian of the traditional rituals, which are believed to be necessary for the well-being of the town. The unit derives its authority from the Olobu.

Politically, the Olobu enjoyed extensive power. He had legislative and judicial powers: He almost monopolised the right to impose or commute capital punishment and also controlled appointments to senior political offices. Though the Olobu has the right to choose his own chiefs, he is himself chosen by the kingmakers. In the palace, the Olobu has some palace officials called 'Oba ni nki o'. This is hierarchically set up with ''Baba kekere" as its leader. The 'Baba kekere' is chosen by the reigning Oba or his chiefs. The palace officials also include the palace chronicler in person of the chief drummer, Are.
