This work investigates the social structures, kinship systems, and cultural practices of the Yako people of Nigeria. Daryll Forde, a prominent anthropologist and former director of the International African Institute, utilizes extensive field research conducted in the mid-20th century to document the complex social organization of the Yako. The text presents a detailed framework for understanding how lineage, land tenure, and ritual authority intersect within this specific West African society.

Scholars of African anthropology frequently cite this text as a foundational ethnographic study of the Cross River region. Readers often note the academic density of the prose, which is intended for researchers and students of social anthropology.
