Alaafin

Alaafin, or The custodian of the Palace in the Yoruba language, is the title of the king of the medieval Oyo empire and present-day Oyo town of West Africa. It is the particular title of the Oba (king) of the Oyo. It is sometimes translated as "emperor" in the context of ruler of empire. He ruled the old Oyo Empire, which extended from the present-day Benin republic to Nigeria, originating from states in the South East and West to the North. The people under him are called Yoruba people and spoke the Yoruba Language.

The Alaafin of Oyo in Yoruba mythology and history is said to be one of Oduduwa seven grandsons who later became Kings, forming the bedrock of the Yoruba Civilization.

The Alafin and the Oyo Mesi formed the central government of the Empire. Local provincial government was in the hands of oba (if crowned head) or bale (if not entitled to wear a crown). The relationship between the Alafin and the Obas was a feudal one, that is for his rule and protection, the Obas, the Bales and chiefs of vassal states owed him certain obligations. By the early 1800s, however, conflicts between the Oyo emperor (alafin) and the hereditary kings (obas) of the core city-states, who comprised an independent executive council (oyo mesi), had considerably weakened cen- tral authority-even as the Oyo Empire began to lose control over outlying kingdoms and city-states.

The title was retained after the fall of the Oyo Empire as the official title of the ceremonial ruler of the contemporary natives of Oyo, Nigeria. The Alaafin is the political head of the Yoruba people and the only monarch with the pre-requisite power to appoint a chieftain representing the entire Yorubaland. Examples of such appointments include Aare Ona Kakanfo of Yorubaland and Iyalode of Yorubaland.

the Alaafin (Emperor) of Oyo was Oba Lamidi Adeyemi III who was the 45th Alaafin, celebrated his 50th year on the throne. Oba Lamidi Olayiwola Adeyemi III, Iku Baba Yeye, Alaafin (Emperor) of Oyo was the permanent Chairman, Oyo State Council of Obas and Chiefs until his death on Friday, 22 April 2022. The style used for Alaafins is Imperial Majesty.
