Jan Jansen has substantially advanced our understanding of the “status discourse” between polities, in Mande and far beyond, through a new approach to one of the more common types of historical evidence: genealogy. At the core of his paper is an analysis of genealogical metaphors used in status discourse, combined with an awareness of the principles of lineage segmentation; he uncovered a nexus of ideology and social structure. The quintessential observation made by Jansen is that “the status of recent immigration and the position of the youngest brother is very prestigious” and that both ultimately emanate from the “principles of patrilocal settlement and patrilineal descent.”
Once this is accepted, everything falls into line: the unexpected claim for the status of ‘younger brother,’ as well as the contradictory genealogies of ‘related’ lineages. His observation has escaped the attention of previous research (including my own) because it contravenes our expectation that younger age, factual or figurative, always signifies subordination under ‘older’ authority. Oral traditions from different ethnic groups in Senegambia confirm Jansen and attest to Kangaba's historical prestige.
Jansen's paper should be read in conjunction with his “The Younger Brother and the Stranger,” in which he studies the social basis of status discourse in more detail and also touches on the symbolism employed. He has overcome a crucial error in a long tradition of historical writing on the western Sudan: the taking of genealogy at face value, whereas genealogy reflects the recent state of relationship between persons or groups rather than factual ancestry.
