The people of Oyo State are Yoruba with a common ancestor, Oduduwa. Within Oyo State however, there are sub-ethnic groups with distinct dialect peculiarities.
The people of Oyo State may be divided into five broad groups, namely: Ibadans, Ibarapas, Oyos, Oke-Oguns and Ogbomosos.
IBADANS
The Ibadans have their settlements in the city of Ibadan and surrounding farms and villages. They trace their roots to Lagelu, a warrior. The city grew around a legendary baobab tree from which it derived its name. It grew quickly, attracting warriors and refugees from the internecine wars that raged Yorubaland in the 18th century. Over the years, the diverse background of the early settlers has evolved into a sub-cultural mix that is unique in Yorubaland. The system of promotion from Compound Head (Mogaji) to the throne is exclusive to the Ibadans. The people are spared the unhealthy rivalry and in-fighting that attends filling of vacant stools. The people were originally warriors and farmers but are now gainfully employed in all areas of human endeavour.
OYOS
The Oyos occupy a geographic location to the north of Ibadan including Oyo town, surrounding towns and villages. In ancient times, Oyo Empire ruled over a sizeable chunk of Yorubaland and beyond. The Oyos were core people of the Oyo Empire. Today, the Empire is no more, but the people retain their proud heritage. They are engaged in all forms of modern business activities and human endeavours. Oyo State is named after the rich heritage of the people.
OGBOMOSOS
The Ogbomosos dwell in the town of that name and surrounding towns and villages. The people have their home on the strategic route linking the northern parts of Nigeria to the south. In times past, they were fearless warriors. They have many things in common with the Oyos in particular and other sub-cultural groups in Yorubaland. Today, the people are established in all areas of modern business and public service. They are renowned traders, and can be located in any part of the country conducting their businesses. They are established all over Northern Nigeria and the West African sub-region.
IBARAPAS
The Ibarapas are scattered over seven major towns and surrounding villages. The towns are: Eruwa, Tapa, Ayete, Igbo-Ora, Lanlate, Igangan and Idere. The Ibarapas have a distinct dialect that separates them from their nearest neighbours. The people have similarities with the Oyos. The people are mainly farmers. Yam and cassava flour (elubo) are major farm products in the area. They also engage in plantation farming-cultivating cocoa and palm produce.
OKE-OGUNS
The Oke-Oguns occupy the guinea savannah area of Oyo State. Many sources ascribe same origin to the Oke-Ogun people and the Oyos. The people are scattered over several towns and villages, namely Iseyin, Saki, Okeho, Igbeti and Igboho, among others. The people are hardworking and hospitable. The people of Oke-Ogun are mainly farmers. The area is tagged the “Food basket” of Oyo State. Weaving and pottery are cottage industries well developed among the people. The people are noted for their business acumen.
