Indigenous allies helped the Spanish gain a foothold in the Americas. What did these Indian conquistadors expect from the partnership, and what were the implications of their involvement in Spain's New World empire? Laura Matthew's study of Ciudad Vieja, Guatemala--the study first to focus on a single allied colony over the entire colonial period--places the Nahua, Zapotec, and Mixtec conquistadors of Guatemala and their descendants within a deeply Mesoamerican historical context. Drawing on archives, ethnography, and colonial Mesoamerican maps, Matthew argues that the conquest cannot be fully.
