Book excerpt: The political conflict during Mexico's Reform era in the mid-nineteenth century was a visceral battle between ideologies and people from every economic and social class. As Popular Politics and Rebellion in Mexico develops the story of this struggle, the role of one key rebel, Manuel Lozada, comes into focus. The willingness of rural peasants to take up arms to defend the Catholic Church and a conservative political agenda explains the bitterness of the War of Reform and the resulting financial and political toll that led to the French Intervention. Exploring the activities of rural Jalisco's residents in this turbulent era and Lozada's unique position in the drama, Brittsan reveals the deep roots of colonial religious and landholding practices, exemplified by Lozada, that stood against the dominant political current represented by Benito Juarez and liberalism. Popular Politics and Rebellion in Mexico also explores the conditions under which a significant segment of Mexican society aligned itself with conservative interests and French interlopers, revealing this constituency to be more than a collection of reactionary traitors to the nation. To the contrary, armed rebellion--or at least the specter of force--protected local commercial interests in the short run and enhanced the long-term prospects for political autonomy. Manuel Lozada's story adds a necessary layer of complexity to our understanding of the practical and ideological priorities that informed the tumultuous conflicts of the mid-nineteenth century.
