This book investigates how the British state and reformist movements redefined the relationship between juvenile delinquency and citizenship during the first half of the twentieth century. Victor Bailey, a historian specializing in social policy and crime, utilizes archival records and institutional histories to examine the evolution of the juvenile justice system. He argues that the shift toward rehabilitative models was driven by a specific class of liberal reformers who sought to integrate young offenders into the national social fabric through state-sponsored welfare and training programs.

Experts recognize this work as a foundational text for understanding the transition from punitive to rehabilitative juvenile justice in the United Kingdom.
