The Afterlives of Segmentary Lineage: (Post-)Structural Theory and Postcolonial Politics in the Horn of Africa

Segmentary lineage theory fell out of favor in cultural anthropology during the 1980s. However, the core ideas of segmentary lineage have continued to shape political mobilization as well as political analysis in Africa long after the theory’s supposed death. This article analyzes how and why the framework of segmentary lineage has endured as a potent means of describing and experiencing politics in the Somali-inhabited Horn of Africa. It theorizes Somali clanship, a classic example of a “pure” segmentary lineage structure, as a framework for managing the near-term future rather than as an objective description of existing social structures. We show how segmentary lineage has been politicized during the colonial and postcolonial eras as a tool for pre-emptive action by governments. We link this broader dynamic of politicization to the functions of clanship in everyday life as a mode of anticipating other people’s likely behavior based on clan-framed narratives about the past. Based on archival research, ethnographic fieldwork, and analysis of media and social media, we argue that Somali clanship operates in politics less as a network of shared interests or mobilization based on anticipated collective gains, and more as a framework for anticipating and attempting to pre-empt other people’s likely behavior.
