Efunsetan Aniwura
Chief madam Ẹfúnṣetán Aníwúrà (c. 1820s–June 30, 1874) was the second Iyalode of Ibadan, a high-ranking female chieftain in most of the Yoruba traditional states. She is also regarded as one of the leading slave dealers in the 19th century in Ibadan.  Her influence was felt in Ibadan's political, military, economic, and religious realms. She became known as a brilliant trader and merchant. She was known for being the most wealthy and powerful Yoruba woman to have ever lived. Historians have characterized her as a powerful ruler who frequently executed disobedient slaves. This has been attributed to a psychiatric breakdown brought on by the loss of her only child and her subsequent infertility.
