This book Nomads at the Crossroads: Society, Ideology and Power in the Arid Fringes of the Southern Levant during the First Millennium BCE] comprises several studies dealing with the society, economy, ideology and power among the mainly tribal, semi pastoral communities living and moving around the southern arid margins of the southern Levant, particularly the Negev desert, southern Transjordan (ancient Edom) and northeastern Sinai during the first millennium BCE. All studies revolve around a central concept: the phenomenon of tribalism. In few words, tribalism constituted the framework around which were structured the local groups' social institutions, economy, politics and ideology. Key topics such as the manufacture and circulation of local ceramics, the exploitation and trade of copper and incense, the local sociopolitical fluctuations and emergence of local chiefdoms, and the ideology of kinship and segmentation are studied under this light."
