AbstractAmong the agro-pastoral Kuria people of East Africa, whose population straddles the border between Tanzania and Kenya, many young men are engaged in an illicit, violent livestock trade in which cattle stolen in Tanzania are sold to Tanzanian or Kenyan buyers for cash. This raiding is inextricably bound up with the phenomenon of warfare between mutually antagonistic Kuria clans, which not only serves to legitimise raids on the enemy's cattle herds so long as the fighting rages but which also fosters and sustains an atmosphere of inter-clan enmity that lends support to cattle raiding, particularly on the herds of former adversaries, even after hostilities have ended. Clan warfare emerges as both a cause and an effect of raiding as well as serving as a training ground for novice raiders. On the basis of field research in the Tarime District lowlands, the article argues that although Kuria cattle raiding, oriented to the cash market, owes its existence to capitalist penetration and is driven by the rising demand for cattle, particularly in Kenya, it remains heavily dependent on inter-clan warfare, which has two main causes: animosity engendered by commercialised cattle raiding, and boundary adjustments initiated by the government, either for administrative reasons or, paradoxically, in an effort to resolve existing disputes over access to pasture, grazing and water.
