Oba Dr Adedapo Adewale Tejuoso, Karunwi III, stands among the notable modern royal figures of Egbaland. Known as the Osile of Oke Ona Egba, his life joins together several worlds that shaped twentieth century Nigeria, Western education, medical practice, family enterprise, civic service, Christian faith and Yoruba traditional authority.
His story is often reduced to one memorable phrase, the doctor who became a king. That description is true, but it is too narrow. Before he ascended the Osile stool, Tejuoso had already trained abroad, returned to Nigeria as a medical doctor, worked in hospital practice and participated in business through the family’s industrial interests. His later role as a traditional ruler did not erase those earlier identities. Instead, it added royal responsibility to a life already marked by public service.
Early Life and Family Background
Adedapo Adewale Tejuoso was born on 19 February 1938 into the Tejuoso family of Egbaland. His father was Joseph Shomoye Tejuoso, while his mother was Chief Esther Bisoye Tejuoso, widely remembered as Chief Bisoye Tejuoso. His mother became one of the most prominent women in Egba public life and was recognised as the third Iyalode of Egbaland.
The title of Iyalode carries deep significance in Yoruba society. It is associated with female leadership, commerce, influence and public responsibility. Through his mother, Tejuoso grew up in a family that was already connected to business, social standing and Egba communal life. That background helped shape the environment from which his own public journey later emerged.
His early years were marked by education in different parts of Nigeria. He attended school in Zaria and later continued his education in Abeokuta, including Abeokuta Grammar School. These educational experiences placed him within a generation of Nigerians who were shaped by both local identity and colonial era schooling. For many young people of that period, education was not simply a personal advantage. It was a route into professional life, public leadership and wider service.

Medical Training Abroad
In 1957, Tejuoso travelled to England. He later gained admission to Trinity College Dublin in 1958 to study medicine. His medical training placed him within a demanding professional tradition and connected him to one of the oldest university institutions in Europe.
After qualifying as a medical doctor, he returned to Nigeria in 1964. He worked at the Lagos University Teaching Hospital, LUTH, during the early years of that institution’s development. In later interviews, he recalled his time at LUTH as part of the beginning of his professional life in Nigeria.
This medical background remains one of the most important parts of his biography. It shows that his public standing did not begin only with royal inheritance. He had already pursued a serious profession, passed through formal medical education and served in a hospital environment before the palace became part of his life.
Business and Family Enterprise
Tejuoso’s life was also connected with business, especially through the Tejuoso family’s industrial interests. The family name became closely associated with Teju Foam and related enterprise. In public interviews and biographical accounts, he has been linked with the management and direction of the family business before his enthronement.
This part of his life is important because it shows another side of his preparation for leadership. Medicine gave him discipline and professional standing. Business gave him experience in administration, organisation and responsibility. By the time he became Osile, he had already moved through worlds that required decision making, public trust and practical management.
The family enterprise also placed him within the changing economic world of postcolonial Nigeria. As Nigerian families, professionals and entrepreneurs began building local industries after independence, figures like Tejuoso stood at the meeting point of education, business ambition and community expectation. His business experience became part of the wider background he carried into the palace.
The Road to the Osile Stool
Oba Adedapo Tejuoso became the Osile of Oke Ona Egba in 1989. Records identify him as the eighth Osile of Oke Ona Egba since the Oke Ona settlement in Abeokuta in the nineteenth century. His reign therefore belongs to a longer history of Oke Ona identity, Egba settlement and traditional authority.
His path to the throne was not one he described as a childhood ambition. In interviews, he said he did not grow up assuming that he would one day become king. He recalled that during the illness of a previous Osile, some people suggested that he might be called to the stool in the future. At the time, he did not see himself as ready for such a responsibility. Years later, when he was about 50, the possibility became real.
The selection process, as he has described it publicly, involved the ruling house, customary procedure and the kingmakers. He also gave his accession a strong Christian meaning, speaking of divine direction and faith. That combination became part of the public character of his reign. He entered a Yoruba traditional office while openly interpreting his journey through Christian belief.
Oke Ona Egba and the Weight of Tradition
Oke Ona Egba is one of the historic sections of Egbaland. Its identity forms part of the wider Egba story associated with Abeokuta’s growth and settlement history. The Osile stool is therefore not merely a personal honour. It is tied to community memory, lineage, authority and public responsibility.
As Osile, Tejuoso inherited an office that carries cultural and symbolic weight. Traditional rulership in Yorubaland is not limited to ceremonies. It involves identity, continuity, counsel, community representation and the preservation of inherited institutions. In modern Nigeria, such offices also exist alongside state government, religious institutions, education, media and civic organisations.
Tejuoso’s reign reflects this layered reality. He is not only remembered as a royal father. He is also known as a doctor, an industrial figure, a Christian public voice and a participant in civic life. These identities have shaped how his reign has been seen by the public.
Faith and Public Witness
Christian faith has remained a visible part of Oba Tejuoso’s public life. In interviews, he has spoken openly about his faith and about the way he understands his throne through a Christian lens. His religious identity has also appeared in public events connected with thanksgiving, worship and moral instruction.
In February 2026, reports recorded the public celebration of his 88th birthday in Abeokuta. The event was also connected with Praise Unlimited, a worship and thanksgiving programme. Traditional rulers, clerics, political figures and other dignitaries were reported among those who attended.
In May 2026, activities marking his 37th coronation anniversary were also reported. During that period, he called attention to the need for character and moral education in schools. This public message fits the wider pattern of his later life, where kingship, faith and concern for social values are repeatedly brought together.
Rotary, Civic Service and National Engagement
Beyond medicine, industry and the palace, Oba Tejuoso has also been associated with Rotary service. Reports identify him as a member of the Rotary Club of Ikeja and a Past District Governor. This connection places him within a civic tradition focused on service, leadership and community development.
His public life also reached national conversations. He was associated with the 1994 National Constitutional Conference, a major political forum in Nigeria’s history. This gives his biography a national dimension beyond his royal role in Egbaland. It shows a traditional ruler whose public service extended into one of the important constitutional discussions of Nigeria’s late twentieth century.
A Reign Preserved in Records
One striking feature of Oba Tejuoso’s public life is the effort to preserve memory through documentation. His reign has been connected with books, interviews, public reports, anniversary events and written reflections. Nigerian Tribune has reported on his three volume work, My 30 Years of Stewardship on the Throne of My Fore Fathers, which recorded activities and reflections from his years on the throne.
This matters because traditional history is often preserved through oral memory, praise names, family accounts and community narration. In Tejuoso’s case, those older forms of memory exist alongside modern documentation. His life can therefore be traced through interviews, newspaper reports, library records and published works.
The written record also helps place his reign within the wider story of Egba leadership. It gives later readers a way to follow the movement of a man who began in professional medicine, served in business and civic life, and later carried the responsibility of an inherited throne.
Legacy of a Modern Yoruba Royal Father
Oba Adedapo Tejuoso’s life is important because it shows how traditional leadership can carry modern experience without losing its historical roots. He was not only a royal figure shaped by inheritance. He was also a trained doctor, a man of business, a Rotarian, a Christian voice and a participant in public affairs.

His movement from medicine to monarchy gives his story a distinctive place in Egba history. It reflects the journey of a man who passed through professional education and civic service before assuming ancestral responsibility. It also reflects a wider Nigerian reality, where traditional rulers continue to serve as symbols of identity, memory and continuity in a changing society.
His life is remembered through several connected paths, a birth in 1938, medical training abroad, service at LUTH, involvement in family enterprise, enthronement as Osile in 1989, public recognition as the eighth Osile of Oke Ona Egba, Rotary service, national engagement and continued public visibility into his late eighties.
Author’s Note
Oba Adedapo Tejuoso’s story reminds readers that leadership can take more than one form in a single lifetime. His journey moved from the classroom to the hospital, from family enterprise to civic service, and from private conviction to the public weight of the Osile stool. The value of his life is not only in the fact that a doctor became a king, but in the way his education, faith, service and royal responsibility came together within the history of Oke Ona Egba and the wider Egba world.
