Following the historiographical character of the police practices, the essays that make up this book analyze those experiences in Mexico from the end of the viceregal period to the post-revolutionary period. From the urban territorial restructuring of the Bourbon period to the emergence of specialized bodies during the last third of the 19th century, police practices pose the challenge to the historian to understand the singularities that each period and space have left to the police power. That is, differences in neighborhood mayors, municipal gendarmes or confidential agents complement our understanding of order and police power.
