The Egba are a subgroup of the Yoruba people who live in western Nigeria. Many Egba live in the city of Abeokuta, capital of Ogun State.
The Egba nation originally under the Oyo empire became independent following the collapse of the Oyo empire in the first half of the 19th century. Tribal wars with the dahomey where the Egba were successful partly due to the protection afforded by the Olumo Rock led to the founding of the city of Abeokuta, which literally means "under the rock".
