Long before colonial rule and centuries before modern machinery transformed landscapes, an extraordinary monument was carved into the earth across what is now Ogun State, Nigeria. Known today as Sungbo’s Eredo, this immense network of ditches and embankments stretches for about 160 kilometres through forests, hills, farms, and ancient settlements, making it one of the largest surviving earthworks in Africa.

At the heart of this remarkable achievement is Queen Bilikisu, also known as Sungbo, a legendary Yoruba ruler remembered for her wisdom, wealth, influence, and enduring legacy. Although history has preserved only fragments of her life, her name has become inseparable from one of Nigeria’s greatest archaeological treasures. Her story combines royal leadership, cultural heritage, engineering brilliance, and centuries of tradition, making her one of the most fascinating women in Nigerian history.

Who Was Queen Bilikisu?

Queen Bilikisu, popularly called Sungbo, was a powerful ruler associated with the ancient Ijebu Kingdom in present day Ogun State. She is believed to have lived between the tenth and eleventh centuries during a period when Yoruba civilization was expanding through trade, agriculture, and political organization.

She is remembered as an influential monarch whose authority extended across numerous communities. Oral traditions describe her as a wise and respected queen who possessed enormous wealth and commanded the loyalty of thousands of people.

Her name has endured for generations because of the monumental earthwork known as Sungbo’s Eredo, a masterpiece of indigenous engineering that continues to inspire historians, archaeologists, and visitors alike.

Early Life

Birth and Origins

The exact date of Queen Bilikisu’s birth is unknown, but Yoruba traditions place her origins within the ancient settlements of present day Ogun State, particularly around Ijebu Ode and Oke Eiri.

She was born into a society where leadership was closely connected with community service, commerce, spirituality, and governance. From an early age, she would have witnessed the importance of cooperation, diplomacy, and strong leadership in maintaining prosperous communities.

These early influences helped shape the remarkable ruler she would later become.

Family Background

Very little is known about Queen Bilikisu’s immediate family, but oral traditions consistently portray her as a woman of noble heritage and exceptional influence.

She ruled over a prosperous kingdom whose economy depended on farming, local industries, long distance trade, and skilled craftsmanship. Under her leadership, communities flourished through cooperation, security, and organized administration.

Her palace became a centre for political decision making, traditional worship, commerce, and cultural development.

Traditional Education and Leadership Training

Like many rulers of ancient Yorubaland, Queen Bilikisu received her education through traditional systems rather than formal schools.

She learned governance from elders, palace advisers, and experienced rulers. She was trained in conflict resolution, diplomacy, agricultural management, religious customs, trade administration, and community leadership.

This practical education equipped her with the knowledge needed to oversee one of the greatest public works projects in African history.

Rise to Leadership

Queen Bilikisu emerged during a period of growing prosperity in the Ijebu Kingdom.

The region occupied an important position along trade routes connecting inland Yoruba settlements with coastal markets. This brought wealth, cultural exchange, and opportunities for expansion.

As her influence grew, she united surrounding communities under a strong political system that emphasized cooperation, security, and development.

Her leadership became known not only for prosperity but also for ambitious projects that demonstrated the strength of her kingdom.

Sungbo’s Eredo, Nigeria’s Greatest Ancient Earthwork

Queen Bilikisu’s greatest achievement is forever linked to the construction of Sungbo’s Eredo, one of the largest ancient earthworks ever created.

The monument consists of a vast ditch accompanied by towering earthen walls that extend for approximately 160 kilometres across forests, rivers, valleys, and ancient settlements.

In several places, the ditch reaches depths of nearly 20 metres, while the embankments rise impressively above the surrounding landscape.

The project required extraordinary planning, engineering knowledge, labour organization, and leadership. Thousands of workers would have participated over many years, moving millions of cubic metres of earth using simple tools made from wood, iron, and stone.

Far more than a defensive barrier, the earthwork defined territorial boundaries, protected settlements, regulated movement, strengthened political authority, and demonstrated the unity and strength of the kingdom.

Even after nearly one thousand years, large sections remain visible today, standing as remarkable evidence of the ingenuity of ancient Nigerian civilization.

The Ancient City of Sungbo

The communities connected by Sungbo’s Eredo formed an important centre of political and economic activity within the ancient Ijebu Kingdom.

These settlements benefited from fertile farmland, thriving trade, skilled artisans, and organized governance. Roads linked neighbouring communities, while markets attracted merchants exchanging agricultural produce, textiles, beads, pottery, iron tools, and other valuable goods.

The earthwork itself symbolized the unity of these communities and reflected the kingdom’s ability to mobilize people for projects of enormous scale.

The ancient city associated with Queen Bilikisu remains one of the most significant historical landscapes in southwestern Nigeria.

The peaceful surroundings and centuries old traditions associated with the tomb have helped preserve Queen Bilikisu’s memory across generations.

Leadership, Vision, and Challenges

Constructing an earthwork of such enormous size demanded exceptional vision and determination.

Queen Bilikisu had to coordinate thousands of labourers, ensure steady food supplies, maintain peace among participating communities, supervise long term planning, and inspire people to work toward a common purpose.

These achievements required extraordinary administrative ability and demonstrate why she remains one of the most respected female figures in Yoruba history.

Her leadership transformed ambitious ideas into lasting monuments that continue to inspire admiration today.
