Meet five longest reigning monarchs in Nigerian history

Nigeria is a country rich in culture and history, and traditional rulers play a major role in maintaining peace, customs, and identity in their kingdoms.

Over the years, some of these royal fathers have ruled for decades, becoming not just custodians of tradition but also key figures in politics, unity, and community development.

One of such highly respected monarchs was the Awujale of Ijebuland, Oba Sikiru Kayode Adetona, who passed away on Sunday, July 13, 2025, at the age of 91.

His death shocked many Nigerians, especially as it came just hours after the announcement of the passing of his close friend, former President Muhammadu Buhari.

His passing was met with deep mourning across Ijebuland and beyond. A prince of Ijebu, Prince Adedoyin Alatishe, expressed his sorrow on social media, posting in Yoruba: “Baami Ogbagba agbatewole.

Erin wo. Omo anikilaya saagbu”, a touching tribute that speaks of the fall of a great elephant, a symbol of royalty and strength.

Oba Adetona ascended the throne in 1960, making him one of Nigeria’s longest-reigning kings.

For over 65 years, he led the Ijebu people with wisdom, dignity, and a strong voice in national matters.

He belonged to the Anikinaiya royal house, and during his lifetime, he contributed greatly to the political, cultural, and economic growth of Ogun State and Nigeria at large.
