Book excerpt: Richard Tapper's 1997 book, which is based on three decades of ethnographic fieldwork and extensive documentary research, traces the political and social history of the Shahsevan, one of the major nomadic peoples of Iran. The story is a dramatic one, recounting the mythical origins of the tribes, their unification as a confederacy, and their decline under the Pahlavi Shahs. The book is intended as a contribution to three different debates. The first concerns the riddle of Shahsevan origins, while another considers how far changes in tribal social and political formations are a function of relations with states. The third discusses how different constructions of the identity of a particular people determine their view of the past. In this way, the book promises not only to make a major contribution to the history and anthropology of the Middle East and Central Asia, but also to theoretical debates in both disciplines.
