Archaeological data from Las Varas, Peru, that establish the importance of ritual in constructing ethnic boundaries Recent popular discourse on nationalism and ethnicity assumes that humans by nature prefer “tribalism,” as if people cannot help but divide themselves along lines of social and ethnic difference. Research from anthropology, history, and archaeology, however, shows that individuals actively construct cultural and social ideologies to fabricate the stereotypes, myths, and beliefs that separate “us” from “them.” Archaeologist Howard Tsai and his team uncovered a thousand-year-old village in northern Peru where rituals were performed to recognize and reinforce ethnic identities. This site—Las Varas—is located near the coast of Peru in a valley leading into the Andes. Excavations revealed a western entrance to Las Varas for those arriving from the coast and an eastern entryway for those coming from the highlands. Rituals were performed at both of these entrances, indicating that the community was open to exchange and interaction, yet at the same time controlled the flow of people and goods through ceremonial protocols. Using these checkpoints and associated rituals, the villagers of Las Varas were able to maintain ethnic differences between themselves and visitors from foreign lands. Las Varas: Ritual and Ethnicity in the Ancient Andes reveals a rare case of finding ethnicity relying solely on archaeological remains. In this monograph, data from the excavation of Las Varas are analyzed within a theoretical framework based on current understandings of ethnicity. Tsai’s method, approach, and inference demonstrate the potential for archaeologists to discover how ethnic identities were constructed in the past, ultimately making us question the supposed naturalness of tribal divisions in human antiquity.

From the earliest days of their empire in the New World, the Spanish sought to gain control of the native peoples and lands of what is now Sonora. While missionaries were successful in pacifying many Indians, the Seris--independent groups of hunter-gatherers who lived on the desert shores and islands of the Gulf of California--steadfastly defied Spanish efforts to subjugate them. Empire of Sand is a documentary history of Spanish attempts to convert, control, and ultimately annihilate the Seris. These papers of religious, military, and government officials attest to the Seris' resilience in the face of numerous Spanish attempts to conquer them and remove them from their lands. Most of the documents are being made available for the first time, while the few that have been published are extremely difficult to find. They include early observations of the Seris by Jesuit missionaries; the collapse of the Seri mission system in 1748; accounts of the invasion of Tibur¢n Island in 1750 and the Sonora Expedition of 1767-1771; and reports of late-eighteenth-century Seri hostilities. Thomas Sheridan's introduction puts the documents in perspective, while his notes objectively clarify their significance. In a superb analysis of contact history, Sheridan shows through these documents that Spaniards and Seris understood one another well, and it was their inability to tolerate each other's radically different societies and cultures that led to endless conflict between them. By skillfully weaving the documents into a coherent narrative of Spanish-Seri interaction, he has produced a compelling account of empire and resistance that speaks to anthropologists, historians, and all readers who take heart in stories of resistance to oppression.
