Source-derived summary

Ilaro is a town in Ogun State, Nigeria. Ilaro's population in 2008 was estimated at 33,000 people, and in 2015 it was estimated to have grown to about 60,000. Ilaro is the headquarters of the Yewa South Local government, known as Yewaland, which replaced the Egbado division of the former Western State, and later became a part of Ogun State of Nigeria. Ilaro town is about 50 km (31 mi) from Abeokuta, the Ogun State capital, and about 100 km (62 mi) from Ikeja, the capital city of Lagos State. Ilaro's area is about 9–9.5 km2 (3.5–3.7 sq mi).

Ilaro is the site of the Olu of Ilaro, who also doubles as the Paramount Ruler of Yewaland. The incumbent paramount ruler is Oba Kehinde Gbadewole Olugbenle, who ascended the throne on 14 April 2012. Oba Kehinde Gbadewole Olugbenle was selected as the Paramount Ruler of The Yewaland by Ogun State governor Ibikunle Amosun, exactly four years after the demise of Oba Samuel Adekanmbi Tella II, who ascended to the throne of Obaship in 1976 after the death of Oba Adetona Amerika. The Olu Ijana of Ijana town, The Oni Igbeji of Igbeji town, Oloja of Oja Odan, The Oni Idogo of Idogo Ipaja, Oni Iwoye of Iwoye town, Olu of Eredo, Olowode of Owode, Olu of Imasayi, Baale of Iweke and other traditional rulers in Yewa Land are some of the kings in Yewa land which the paramount ruler rules over. Close to this monument is the town hall named after the warrior Orona Hall, whose statue is nearby.

Editorial summary

Editorial reviewA strong orientation record where physical form, institutional use and historical geography need to be read together. The current lead gives the account dated anchors—2008, 2015, 2012, 1976—that can be checked directly. The selected authority fields contribute no independent date.

Editorial analysis

Why this record matters

The phrase “town in Ogun State, Nigeria” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 20, 2026. The linked authority identifier is Q5997200. VIAF identifies the subject as 145307581. Authority coordinates are 6.890, 3.017. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2008, 2015, 2012 and 1976.

Critical limits

Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
