The Egba are a clan 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 spectacular collapse of Oyo in the first half of the 19th century. Tribal wars with the Dahomey where the Egbas 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".
The Egba nation is made up of the following sub-divisions - the Ake, Owu, Oke Ona and Gbagura, each with its own king. During colonial rule the British recognised the Alake (or King of Ake) as the paramount ruler of the whole clan and their territory, and so, his successor is referred to as the Alake of Egbaland now. The titles of the kings of the aforementioned sub-divisions are therefore Alake of Egbaland, Oshile of Oke Ona,Agura of Gbagura" and "Olowu of Owu in order of settlement and seniority in Egba nation. It is worthy of note that the original town and settlement of the Egba nation was under and around Olumo rock, which is in Itoko, in the Egba Alake. The Jagunna of Itoko, is the Chief Priest of Olumo. The areaa in Ikija, which is Oke Ona, is only an amusement park created as an entrance to the park. The entire Olumo Rock is in the territory of, and under the control of the Itokos. Another reference name for Abeokuta by the founding fathers is Oko Adagba (Adagba's Farm or Bush) in reference to the hunter that founded / discovered Olumo rock. Adagba went hunting in search of game animal / food from the Obantoko township where his fellow Itoko citizens were stationed while wandering for a settlement. Egbaland was not only where Henry Townsend lived but also boasted of being the home of the first newspaper in Nigeria ("Iwe Irohin"). Its people serve as the first of the many Nigerian nations (until recently, the only of them) to have had an anthem.
