The Middle Horizon period (A.D. 600–1000) was a time of sweeping cultural change in the Andes. Archaeologists have long associated this period with the expansion of the Wari (Huari) and Tiwanaku (Tiahuanaco) states in the south-central Andes and the Pacific coasts of contemporary Peru and Chile.
 
Tenahaha and the Wari State contains a series of essays that challenge current beliefs about the Wari state and suggest a reassessment of this pivotal era in Andean history. In this collection, a picture emerges of Wari power projected across the region’s rugged and formidable topography less as a conquering empire than as a source of ideas, styles, and material culture voluntarily adopted by neighboring peoples.
 
Much of the previous fieldwork on Wari history took place in the Wari heartland and in Wari strongholds, not areas where Wari power and influence were equivocal. In Tenahaha and the Wari State, editors Justin Jennings and Willy Yépez Álvarez set out to test whether current theories of the Wari state as a cohesive empire were accurate or simply reflective of the bias inherent in studying Wari culture in its most concentrated centers. The essays in this collection examine instead life in the Cotahuasi Valley, an area into which Wari influence expanded during the Middle Horizon period.
 
Drawing on ten years of exhaustive field work both at the ceremonial site of Tenahaha and in the surrounding valley, Jennings and Yépez Álvarez posit that Cotahuasinos at Tenahaha had little contact with the Wari state. Their excavations and survey in the area tell the story of a region in flux rather than of a people conquered by Wari. In a time of uncertainty, they adopted Wari ideas and culture as ways to cope with change.

“This book is a very nice addition to the literature on the Middle Horizon. It is solidly researched, well documented, and balanced in its perspective on the role of Wari in the Cotahuasi Valley during this period. The collection presents detailed evidence from one valley for Wari influence in a context that is clearly not imperial. While not denying that Wari may have been an empire, it adds to a growing body of evidence that all Wari influence, in all regions of Peru, cannot be ascribed either to conquest or hegemony. As such, the volume provides evidence for the role that regional groups played, as agents, in accepting, filtering, and channeling Wari influence.”

“The contributors make a convincing argument suggesting that the site was probably not occupied on a permanent basis and probably served multiple purposes. The volume will be of great interest to scholars working in the Andes and other anthropological archaeologists who address imperialism.”
