"Oba" is a title used for traditional rulers in many Nigerian cultures, particularly among the Yoruba people. "Igbo" refers to the Igbo ethnic group, one of the largest in Nigeria. The combination "Oba Igbo" creates a title that merges the concepts of traditional Yoruba monarchy with the cultural heritage of the Igbo people. The monarch often has a vested interest in education because an educated populace contributes to the stability and prosperity of the kingdom. The monarch may also use skulls as a tool for indoctrination or to cultivate loyalty among the populace, ensuring their support for the monarchy's legitimacy and authority.
