"[An] eye-opening examination of the different hierarchies and ideologies employed by prison gangs around the world. . . . A revealing study with broad implications for policymakers and law enforcement."

Kirkus Reviews

"Academic criminologist Roth offers an unprecedented historical and global perspective on prison gangs. He challenges stereotypes and misconceptions—not all prison gangs are harmful; some provide a sense of order that staff cannot. Roth explores a wide range of gangs, from the Bladebaaz gangs in India to the Camorra in Italy to South Africa's Numbers gangs; he also looks at gangs in North America, Latin America, Oceania, and Europe. His scholarly, meticulous analysis of the various types of organizations and comparisons will give readers a stronger understanding of these prison subcultures—for instance, in the Philippines, the Sigue Sigue groups are considered to be of higher status than the Visayan gangs (Manilan housekeepers tend to come from the Visayan-speaking demographics). Roth illuminates the motivations, behavior, and activity of the organizations both inside and outside of prison and discusses how members function within the prison environment. Roth's well-written, deeply researched work is a must for those in the criminology and criminal justice fields, but interested general readers will find it accessible as well."

Library Journal

“Who wields power ‘inside?’ Roth's chilling and fascinating comparative history of prison gangs demonstrates how far prisons across the world can be considered micro-states, with gangs the crude and exploitative authorities that emerge to run them through violence, fear—and a rough-and-ready sense of order.”

Mark Galeotti, author of "The Vory: Russia's Super-Mafia "

“Finally, a historical analysis of prison gangs worldwide. This book by Roth sets the new standard for prison-gang scholarship. It offers a cross-cultural and cross-border factual analysis of a major international problem not yet addressed by the United Nations. The material on organized crime alone makes this required reading and a reference work for all libraries.”

George W. Knox, executive director, National Gang Crime Research Center, Chicago, IL

“This is a thoroughly researched, well-illustrated, and yet accessible account of prison gangs, which has the advantage of being both historical and global in its reach. Above all, it was a joy to read.”

David Wilson, emeritus professor of criminology at Birmingham City University, former prison governor, and well-known TV and radio presenter

"Demonstrates both the variations in and similarities of prison gangs through time and around the world. There are few books of this scope or importance."

Scott H. Decker, Foundation Professor of Criminology and Criminal Justice, Arizona State University

"An ambitious and stimulating account that draws attention to the historical and cultural contexts in which the prison gang phenomenon has emerged worldwide. Power on the Inside should be essential reading for scholars and students in the comparative prison studies field."

Sacha Darke, senior lecturer in criminology, University of Westminster

"This is a timely book that brings together research from around the world rather than focusing on North America and Europe. In doing so, Roth demonstrates the need for, and generates ideas for, research on prison gangs in other nations."

Mark Lauchs, associate professor of criminology, Queensland University of Technology
