Livestock raiding among northern Kenya’s pastoralists has changed profoundly in the last decades. Fought with modern weaponry and often extreme violence, raiding is increasingly enmeshed in politicized claims over administrative boundaries, struggles for exclusive access to land, and attempts to establish or safeguard an ethnically homogeneous electoral base. These conflicts are part of Kenya’s troubled politics of decentralization and as such they must be viewed in the context of wider political developments in the country. Based on ethnographic fieldwork in East Pokot and surrounding areas in Kenya’s Central Rift Valley Province, this article demonstrates how livestock raiding emerges as a specific form of violent regulation, a well-adapted, dangerous, and powerful political weapon. THE DEADLY ATTACK ON 42 KENYAN POLICE OFFICERS in Suguta Valley, Samburu District in mid-November 2012 sadly reminds us of the ongoing violence in East Africa’s pastoralist areas. What is probably the most deadly attack on police forces in Kenya’s history is but ‘a drop in the ocean’ compared to the daily suffering of the population in these areas, as a commentator in the Nairobi-based Daily Nation points out. Indisputably, the persistent violence in the pastoral areas in north-eastern Africa has detrimental social and economic effects. *Clemens Greiner (clemens.greiner@uni-koeln.de) is a postdoctoral researcher at the Department of Cultural and Social Anthropology, University of Cologne, Germany.
